From nuclear explosions to social-
network-time siphons, the emerging
generation must consider how much
technology is affecting their lives. Au-
thor and social critic Tom Wolfe, and
electrical engineer and Dean Pramod
Khargonekar offer their opinions on
society's technology infatuation.

A wilting healthcare system is in
desperate need of a super-charged
injection of... something. Engineering,
perhaps? Yes, we think that's just what
the doctor ordered.

It wasn't easy for women to earn their
engineering chops So years ago. Heck,
even 20 years ago women still faced
discrimination based on everything but
their ability. It's 2009, things are
a lot better, but women engineers are
still in search of equality


Dean Pramod Khargonekar writes his last letter from 300
Weil Hall before he steps down as dean this summer.
Get engaged by research endeavors, robots, Oompa-Loompa
inspired clean suits, and everyday Gator-Engineered brilliance.
All the alumni news that's fit to print.
There's a lot happening in the College, but there's also a lot
that still needs to done. See how you can help.

It seems like yesterday
when I wrote excitedly on this page
about our return to Gainesville after 17
years in the Midwest and being amazed
by all the changes that had taken place,
such as the demise of our favorite res-
taurant Brown Derby (We learned later
it had burned down.) Sadly, Alachua

education, research, and outreach de-
voted to serving the people of the State of
Florida, the nation, and the world. While
only history can be the judge, I hope we
made major strides toward this goal.
There were many challenges: fierce
worldwide competition for talented fac-
ulty and students, budgets, rapid changes
in engineering, and economic globaliza-
tion to name just a few Among all
these, our central focus was on attracting
and retaining the most talented faculty
and students and providing them with an
exciting environment for research and
education, state-of-the-art infrastructure,
and support to excel. I hope we did this
well as it is the single most important
determinant of our future.
The University of Florida, one of the
largest public research universities in
the world, is the best exemplar of the
challenges and opportunities in higher
education. I aimed to balance competing
missions of undergraduate education,
graduate education, advanced research,
and public service. In a cross weave, I
strove to align the long-term interests of
students, with ambitious aspirations of
faculty and stiff demands placed on staff
These exercises in striking the right bal-
ance, finding deep interconnections, and
fostering the synergies between educa-
tion and research taught me a lot about
how to lead in a major public research
university I hope the College community
will continue to explore these synergies
and interconnections so we continue to
improve all aspects of engineering educa-
tion and research for serving humanity
During this exhilarating journey, my
wife, Seema, and I made many friends.
We will cherish these relationships and
bonds. We are so grateful for the affec-
tion and love we received during these
last eight years. While I will no longer
be the Dean of Gator Engineering, we
will remain the biggest boosters for
successes of our students, faculty, staff,
alumni and friends.

Students from the Machine
Intelligence Laboratory
showed off their creative
sides while strutting their
engineering prowess during
this year's robot demo day.

C oin Frog, the coin-collecting
robot that works underwa-
ter and collects treasure at
the bottom of money-in-
fested fountains, along with
21 other student-produced robots, was
presented to the media and guests at the
annual robot demonstration this spring.
Eric Schwartz, associate direc-
tor of the UF Machine Intelligence
Laboratory and a master lecturer in the
Department of Electrical & Computer
Engineering, said he started the dem-
onstration day in order for people to
see all the hard work his students had
done throughout the semester.
The class, called "Intelligent Machines
Design Laboratory," is made up of half
graduate students and half undergradu-
ates. It includes mechanical, electrical
and computer engineers, Schwartz said.
He said a class like this allows
students to apply the theory they've
learned in other classes in a hands-on,
practical way, and allows students to see
the results of their education.
"This is real engineering," he said.
"This is real stuff."
He also said creating a robot takes a lot
of dedication to not only building the ma-
chine but also researching and finding the
least expensive parts to build the robot,
which could appeal to future employers.
"This is a class that gets people jobs,"
he said. "[Employers] are going to ask
you about your robot."
He said some of the most impressive
robots this year includedJohn Kurien's
Tim TeBOT, a robot that could play
paper football; Timothy Martin's Woody,
which uses a Nintendo Wii remote to
detect fire and then extinguishes it while
playing music; and the Gator Aider Park-
ing Attendant, created byJared Bevis. o



New research findings could lead to faster, smaller
and more versatile computer chips. BY AARON HOOVER

F irst isolated in 2004, graphene a i-atom-thick material has spurred
great excitement in the chip research community because of its promis-
ing electrical properties and bare-minimum atomic size.
Scientists and engineers believe after decades of development, silicon is
fast reaching the upper limits of its physical performance. If the rapid evolu-
tion of ever-shrinking, ever-more-powerful, ever-cheaper semiconductors is to con-
tinue, they say, new materials must be found to complement or even replace silicon.
Graphene is among the leading candidates for these nanoelectronics of the future.
A team of scientists and engineers from Stanford, the University of Florida and
Lawrence Livermore National Laboratory is the first to create one of two basic types of
semiconductors using graphene, the exotic new material. The findings could help open
the door to computer chips that are not only smaller and hold more memory but are

also more adept at uploading large files,
downloading movies, and other data- and
communication-intensive tasks.
A paper about the findings, co-
authored by eight researchers, was pub-
lished this May in the journal Science.
"There are still enormous challenges
to really put it into products, but I think
this really could play an important role,"
said Jing Guo, a UF assistant professor of
electrical and computer engineering and
one of two UF authors who contributed.
The team made, modeled and tested
what is known in the industry as an
"n-type" transistor out ofgraphene na-
noribbon. Graphene is a form of carbon
that has been called "atomic chicken
wire," thanks to its honeycomb-like
structure of interconnected hexagons.
A graphene nanoribbon is a nanometer-
wide strip cut from a graphene layer.
The team's feat is significant because
basic transistors come in only two forms -
"p-type" and n-type referring to the
presence of holes and electrons, respective-
ly P-type graphene semiconductors had
already been achieved, so the manufacture
of an n-type graphene semiconductor com-
pletes the fundamental building blocks.
"This work is essentially finding a new
way to modify a graphene nanoribbon
to make it able to conduct electrons,"
Guo said. "This addresses a very funda-
mental requirement for graphene to be
useful in the production of electronics."
Researchers at a number of institu-
tions have reported using graphene to
create a variety of simple transistor de-
vices recently, with the Massachusetts
Institute ofTechnology reporting in
March the successful test of a graphene
chip that can multiply electrical signals.
Guo said the team built and modeled
the first-ever graphene nanoribbon n-type
"field-effect transistor" using a new and
novel method that involves affixing nitro-
gen atoms to the edge of the nanoribbon.
The method also has the potential to
make the edges of the nanometer-wide
ribbon smoother, which is a key factor to
make the transistor faster.
"This uses chemistry to really ad-
dress the major challenges of electrical
engineering when you get into such these
small nanoscale dimensionalities," he said.
"It is very unusual for electrical engineers,
who are used to dealing with bulk struc-
tures of at least millions of atoms." o

Building a Career in Academia BY MEGAN E. GALES

no time card to punch, no priorities imposed and the freedom to explore.
Even if the post-college career path led far away from noble gothic walls
and lovely vine-clad halls, with a little strategic planning in three pri-
mary areas the Savvy Engineer can make the jump back into academia.

RESEARCH: Will you add to
the knowledge base?
At research institutions, research will
determine your success or failure. You'll
do a lot of research through your stu-
dents. They'll need help. They'll break
stuff. But they'll learn, and that can be

extremely rewarding. Entrepreneurial
talent will serve you well, because lead-
ing a research group is a lot like running
a small business. You'll fund most of
your expenses equipment, supplies,
Ph.D. students, and even your summer
paychecks from grants.

"Fundamental DON'TWAIT Build a strong
research is no publication record now. You won't
longer done in land the job without one. Get to know
companies. If funding agents, too. Network through
ouil w.,ant to rl technical conferences.

true research, it
has to be done
at a university."
Professor of
Electrical &
Engineering who
came to UF after
12 years at Intel

TEACHING: Do you like students?
Students bring college campuses
to life. At a major research
university, like UF, you'll teach one
or two classes each semester and
mentor Ph.D. students. At a small
teaching college, you'll teach a
diverse array of about four classes
each semester.

"If I explain something to the students
and they don't understand, it's my
fault. I haven't explained it well
enough. So I continuously evaluate
my delivery. I try to get them excited
about the topic. The more students
ask questions, the happier I am."
Byron D Spangler Professor of Civil & Coastal
Engineering and Director of the University
Center for Excellence in Teaching

PRACTICE NOW. Volunteer to mentor
interns who spend the summer with
your company. Serve as an adjunct in-
structor or mentor at a university. Offer
to give a seminar at a local college or
even your alma mater.

SERVICE: Are you willing to help
your colleagues?
It takes more time to run academia
than many people realize. You'll be ex-
pected to serve on various committees,
mentor junior colleagues, and generally
share in the governance of your insti-
tution. There's also an obligation to
maintain and nurture your discipline.
External service will help you build
a reputation within your field, which
you'll need when it comes
time for tenure.

"It's critical to keep your eye on future
directions. Make sure that you identify
and seize new opportunities."
Distinguished Professor of Materials Science
& Engineering and 2008-2009 UF Teacher/
Scholar of the Year

START TODAY. Involve yourself in
professional societies. When you apply
for a job, you'll already have a record of
service to reference. o

Glenn Sjoden's research on detect-
ing special nuclear materials enables
him to analyze and optimize
neutron and gamma ray transport
for detection, nuclear power or
forensics in almost any scenario.
Most of his research deals with
three-dimensional transport theory,
which uses parallel codes and high-
performance parallel computers to
estimate the levels of radiation and
its effects as it transports and scat-
ters in a system.
"Knowing where the radiation
goes is priceless," said Sjoden,
UF associate professor of nuclear
With co-author and nuclear engi-
neering chair Alireza Haghighat, he
has written some of the codes used
in transport theory applications,
including one code called PEN-
TRAN recently shown to solve a
system Of 5 billion unknowns on
thousands of processors.
"Right now, it's the only code in the
world tested to that level he said.
Sjoden and the UF Transport
Theory Group worked with IBM
and Tanguy Conran, a visiting sci-
entist from Electricite'de France
the past year to analyze a whole
reactor core with PENTRAN.
Sjoden said he and his graduate
assistants at the time Kevin
Manalo, Tom Plower and Mireille
Rowe adapted PENTRAN to
analyze fuel burn-up in a nuclear
reactor with a post processing code
called PENBURN. They used
because the code solves unknowns
in angle, energy and space over a
three-dimensional mesh.

The Big Stretch



Robots. Satellites, Muscles, Oh My!

Warren Dixon could help stroke pa-
tients gain more precise control of their
muscles and motion during rehabilita-
tion while experiencing less fatigue.
He's also using the same technology to
improve satellite and robot function.
Dixon, an associate professor of me-
chanical and aerospace engineering, is
developing new mathematical formulas
to predict the behavior of nonlinear
systems,which can lead to better con-
trol. Since nonlinear systems include
anything from robots to satellites to
the human body, Dixon's research has
numerous applications, all falling under
the same mathematical umbrella. "We
have this philosophy that the more
information you have about the way
a system is going to behave, the more
sense you have to be able to do what you
want to do," he said.
The common theme all of these ap-
plications is Lyapunov theory, which

is based on "if a function is lower
bounded and always decreasing, then
the function will remain bounded and
converge to the lower limit," Dixon
explained. He said his research group
is building on Lyapunov methods to
construct new control designs and
stability analyses.
One of Dixon's most intriguing
projects deals with muscle stimulation
and could help stroke patients
in rehabilitation.
Muscle activity is one of the most
nonlinear and uncertain systems
because it varies depending on the
person and the circumstance, Dixon
said. Nonetheless, his group tries to de-
velop a Lyapunov-based mathematical
formula that takes into account factors
such as muscle fatigue, muscle fiber
type and pH levels and tries to predict
the best level of stimulation required to
move the muscle a certain amount.



Using a vehicle that records data such as how a driver
changes lanes and how much distance a person keeps be-
tween him and other cars, allows researchers to catego-
rize drivers as aggressive or conservative, explained civil
and coastal engineering professor Lily Elefteriadou.
The researchers then incorporate driver behavior into
the algorithms at the core of traffic simulation software.
So if a city knows which types of drivers are most com-
mon in its population, then it can create a more realistic
simulation to figure out the optimal highway design.
"The presence of very aggressive or very conservative
drivers has an impact," said Elefteriadou, director of
the Center for Multimodal Solutions for Congestion
Mitigation. For example, cities might want to adjust
the number of lanes on a highway because aggressive
drivers tend to quickly move over to the left lane after
entering the freeway, thus causing all of the surround-
ing cars to accelerate, she said.
The CMS was established in May 2007 and is feder-
ally funded. It is one of only a handful of such centers
in the U.S. and is affiliated with the Transportation
Research Center, which has been at UF since 1972.
Elefteriadou is also the director of the TRC.
The traffic simulation software developed at the
CMS is distributed through McTrans, another
affiliate of the TRC.
Elefteriadou said that although several universities
develop and use their own simulation software,
UF's software is the most widely distributed for
commercial purposes.

Disrupting Cancer

After a tumor is
removed from a
cancer patient's
esophagus, the
patient would
likely receive a
stent to keep the
esophagus walls
from collapsing.
But a common
problem with an
esophagus stent is
cancer cells adhere
to the stent surface
and then multiply
on it, causing more
blockages, said
chemical engineer
Tanmay Lele.

This process
requires the
generation of
mechanical forces
that are exerted on
the stent surface.
To keep the cells
from adhering to
the stents, Lele
tries to stop the
cells from exerting
those forces in the
first place by creat-
ing nanostructures
that disrupt the
processes happen-
ing on the cell's

The nanostruc-
tures specifi-
cally disrupt the
clustering of
receptors called
integrins, which
recognize and
bind to adsorbed
proteins on
the stents. The
integrins need to
cluster to transmit
force from the
intracellular acto-
myosin cytoskel-
eton to the
stent surface.
Lele hopes to
disrupt tumor-cell
attachment to the
stent surface by
spacing out the

nanostructures to
prevent integrin
clustering. Initial
experiments show
strong potential
for this approach,
he said.
The American
Heart Associa-
tion has funded
a great deal of
Lele's research
because altered
mechanical forces
are also respon-
sible for artery
blockages, so un-
derstanding how
cells respond to
mechanical forces
is key to under-
standing heart

An integrated circuits design group is developing low-
power microsystems to sense and process brain signals
using various steps of algorithms. The microsystems
then wirelessly transmit those processed signals to an
external device that controls movement, explained
electrical and computer engineering assistant professor
Rizwan Bashirullah.
Since these microsystems would be implantable
electronic devices, they must be small and low-power
but highly functional; they have to be able to sense the
low-noise and highly parallel brain signals while using a
minimum amount of power so the device does not over-
heat, said Bashirullah, an assistant professor of electrical
and computer engineering.
As a self-described "hardware guy," Bashirullah said
he focuses on developing algorithms that can work
within these constraints.
"Not every algorithm is hardware- or energy-efficient,
so one of the things that we're trying to do is basically
create algorithms that are very hardware-efficient in
terms of the amount of space [and] the amount of compu-
tational energy required," he said.
He's also working on a separate low-power micro-
system that could save the pharmaceutical industry
billions of dollars each year, which could translate into
lower health care and drug costs.
Bashirullah is developing a biocompatible electronic
microchip that can be placed on a pill capsule and moni-
tored from outside the body to track the pill's trajectory.
"It's an electronic tag or time stamp associated with
the patient ingesting the pill," he said.
As of now, it's difficult to track whether patients in a
clinical trial are actually taking the prescribed drug, which
makes it hard to infer the accuracy of the results, he said.
Like the microsystems that process brain signals, this
device is small, wireless and low-power, he said.

An idea that began more than five years ago to construct
a building to encourage interdisciplinary research
between engineering and medicine will open its doors
late this summer. BY STEVE MILLER

it's not a coffee shop or a lounge,
although the tables, chairs, multi-
level layout and floor-to-ceiling
windows may imply such.
Instead, it's the atrium of the UF
Biomedical Sciences Building, which
will open for business in August.
The idea of the airy setting is to
encourage socializing, which can
sometimes be an awkward gesture
in the intense world of biotech,
medicine and engineering, all of
which will be holding hands in the
new building.

wood paneling and metal detailing
befitting a modern loft, is a mingling

Rarely do concrete slabs, fiberglass beams
and hyper-active air-filtration systems
become necessary research tools, yet these
are integral to the success UF's Nanoscale
Research Facility. BY KIM WILMATH

It's tough to see what goes on behind the wide-windows of U F's
Nanoscience Institute for Medical and Engineering Technology It's
not that the scientists who work there are secretive about their work.
Heck, they'll even let you zip on a protective suit and wander around
the facility's clean room. It's just the stuff they tinker with is smaller than
the diameter of a human hair, smaller than single cells or bacteria.
The facility was built about a year ago with $35 million in state
funding, said center director Bill Appleton. Researchers and stu-
dents in the Colleges of Engineering, Medicine and Liberal
Arts and Sciences get access to the complex tools needed for
nano-scale research, in addition to other universities, industries
and national labs being welcome to use the facility.

Walk through the front doors of the NRF building and look down.
In the middle of an expansive blue-and-green mosaic is a tiny
piece of gold, about the size of a dime. Artist Robert Stout cre-
ated the work to illustrate the relative size of a nanometer, which
is a billion times smaller than a meter stick. Appleton explained
if a nanometer was blown up to the size of a dime, a meter stick
would be the size of the earth's diameter in comparison.

When it comes to
working with nano-
meter-sized objects,
even the smallest
particles can cause
a big disruption.
NIMET's state-of-
the-art clean room
helps cut down on
such interference.
Anyone who enters
must wear a hairnet,
shoe booties, a
thick white suit, a
hood, another pair
of boots and rubber
gloves. The actual
laboratories are sep-
arated from the rest
of the building by
two chambers and a
long hallway The air
inside is completely
filtered five times
every minute to
remove particles,
and all equipment
is cleaned at least
twice before it's
placed inside. Scien-
tists can't even bring
in regular paper "It's
like an operating
room in a sense,
Appleton said.

The building's design also cuts down on the
shock from the earth's natural movement and
changes in its electromagnetic field. Fluctua-
tions, caused by things like busses driving by
or metal elevators, could make it impossible
to accurately look at nanometer-sized objects
with atomic-resolution microscopes. A thick,
extraordinarily wide concrete slab was built
underneath the first floor's imaging suites,
separate from the rest of the building's founda-
tions and big enough to temper outside vibra-
tions. To avoid electro-magnetic interference
metal is not used in the room's construction,
and even the slab's interior supports are made
of fiberglass. In addition, the lab closest to an
elevator is shielded with metal to divert away
any additional magnetic interference.

NIMET research involves using ion beams to
pattern nanoscale devices, like airbag sensors,
semiconductor circuits, or cell phone compo-
nents. The UF lab is the first in the U.S. to have
this particular ion-beam lithography tool. Most
labs use electron-beams, which are effective,
but not as efficient. The ion technology can
create intricate circuit components onto silicon
by exposing resists or sputtering patterns
directly into the sample and can be more
versatile than electron beams, Appleton said.

Upstairs interactive
workstations and labs
house the Center for
Nano-Bio Sensors
where scientists from
UF's medical and en-
gineering colleges are
developing breath-
sensors to detect
human diseases or
drugs. Similar to an
alcohol breathalyzer, a
hand-held sensor with
nanoscale materials
and components
detect proteins or
molecules in human
breath that point to
various conditions,
such as low blood-
sugar, internal trauma
or anthrax-poisoning.
At least 15 different
industries are in-
volved in the project,
Appleton said. The
Center is a $4 million
Center of Excellence
funded by the State
of Florida.

With use of the NIMET facilities, chemical engineering distinguished
professor Fan Ren helped create an extra-sensitive, more accurate
chemical sensor It's used for things like early detection of cancer and dia-
betes patients' glucose monitoring. The sensor has a highly specialized
electron transistor on its surface, yielding faster, more reliable medical
test results. For instance, instead of women undergoing mammograms
and waiting weeks for results, a simple saliva test on one of Ren's sensors
could provide results almost instantly The device can also be used to
detect kidney failure, prostate cancer, pH levels in the blood and toxins
in the body with saliva or breath tests. Ren said a few companies have
approached UF with an interest in marketing the technology

Six centuries ago a mere eyebrow twitch in the grand
scheme of history information existed in hand-copied
books owned only by the wealthy and the clergy. Today, a
buffet of information is a couple clicks away from a 6-year-old
with his mother's laptop.
It's all happened so fast, in that figurative twitch. A century
ago, people still had to go to libraries or bookstores to find
out stuff. Today's students have advantages even their parents
didn't have 20 years ago. Unlike
mom and pop, these kids can copy- "
and-paste from aWeb site and com-
mit plagiarism without cracking a KA
book. And they don't need to go to REA LLY M
Barnes & Noble to actually buy a
book. They're set up for one-click UJ W I ER
shopping on Amazon. I
Nobody (least of all an engineer) A
wants to turn back this Tsunami of A N D TRU L
advancing information. With its
focus on improving the world and
making life better, engineering has
made this truly incredible informa-
tion technology possible.
But that doesn't mean there's
anything wrong with raising a W HOL E N(
hand, asking a few questions, and N
suggesting maybe we should pause
and consider what's going on. O F N FO R
The hand belongs to Pramod
Khargonekar, outgoing dean of the \ / E RLO A
University of Florida College of En- V L
gineering. As he contemplates life
post-deanship, he'll be returning to
the classroom. He sees himself stand-
ing in front of 18- and 19-year-olds,
helping them deal with the growing A
information overload this generation ,
faces. It's a problem their parents and -PRA
grandparents didn't have.
"It's clear that of all the technological developments in the
last half century, information technology has truly revolu-
tionized the waywe live," Khargonekar says. "And I don't use
the word 'revolutionized' casually."
The information explosion changed the world on a scale
equal to the transformations wrought by automobiles and air
travel, he says, because all of them profoundly affected the
way people live.
In 2006, Khargonekar taught a freshman course called In-
formation Technology and Society, and that class might serve

as the dress rehearsal for what he does in his post-deanyears.
Talking to young people about this technology he watched
develop which was as integral to the students' childhoods
as SpongeBob SquarePants was eye-opening.
"I wanted to tell students that technology doesn't live
by itself," Khargonekar says. "Technology creates change
and change creates new societal issues. I wanted us to look
at the interplay between technological developments and
societal developments. I wanted
students to see technology and
not view it as magical, as this
thing that just happens."
A K N G But what is still new and magical
for the professor is old stuff to the
D E E students. Information overload is a
I E P LE way of life to them. Today's college
Y freshmen were born in the early
199os and they can't remember a
world without the Internet.
To this generation, technol-
ogy is life. It has, among other
things, redefined the basic hu-
FH E man concept of friendship. With
the online social-networking site
T |ON Facebook, students can friend
I (note verb) people they don't
SAT KI N really know, and they become
M AT I N Facebook Friends, something
very different, with different
D AN Dresponsibilities and obligations,
from real friendship. A Facebook
Friend, for example, doesn't have
to help you move out of your
apartment. A real friend doesn't
get off the hook so easy.
Facebook, of course, is so 20oo8.
The new social-network kid on the
MOD KHARGONEKAR block is Twitter, which demands
brevity (140 characters per post)
and reduces life to a series of trivialized updates called "Tweets"
by participants: "In line at the grocery and I forgot the panty-
hose!" "I am so over this lecture." "Running late no coffee for
me." (If you have second thoughts and want to erase your post,
the program asks,"Delete this Tweet?" a sentence thatwould
have meant nothing outside a birdcage mere months ago.)
Khargonekar does not have a Twitter account, though he
muses about the possibility. Still, he sees it as a tool with
great potential, both for transmitting information and also
for the trivialization of human life.

With four
out of five teens (17
million) carrying a
wireless device, 47
percent of teens
saying their social life
would end without
their cell phone and 57
percent believing their
mobile devices have
improved their lives, it
really makes one want
to stop and smell
those roses.

The plethora of technological devices developed to save
time also ends up consuming much of it and, as Ernest Hem-
ingway said, "Time is the thing we have the least of."
Novelist and social critic Tom Wolfe is among those who
arch eyebrows over the time and labor-saving devices grant-
ed us by technology. Such things as iPhones and Twitter
"waste more time than anything else in American life," he
says. "The computer and the Internet are the contemporary
versions of knitting and badminton in the backyard, except
that they have nothing to show for it afterward, the way
knitting does, and lead to atrocious sedentary posture and
sloth, unlike badminton."
Wolfe's social criticism has marked his journalism and
his fiction, most notably in his satirical novel The Bonfire of
the Vanities. As the man responsible for tagging those who
achieved adulthood in the 1970s as "the Me Generation,"
Wolfe's antennae are alert to any new examples of silliness
and narcissism. Tweeting one's most mundane activities is
high goofiness indeed.
Khargonekar agrees with Wolfe. What's most important,
he says, is howwe use technology. It's easy to fall in love with
each new device and development. "There is euphoria with
any new technology," he says. "Of course, there are excesses
that happen, but in time these things will take their place in
the scheme of things."
But critics such as Wolfe worry "these things" that are
supposed to make life better could make things worse. He
uses ThomasJefferson as an example. He had at least eight
careers in addition to his job of creating American democ-
racy. "Today," Wolfe laments, "two-thirds of his life would
be consumed answering inane e-mails." If Jefferson had a

Twitter account, we might all still be foreigners.
By all accounts,Jefferson answered every letter he ever re-
ceived and, Wolfe points out, he used the "outmoded tech-
nology" of pen and ink. Wolfe's favorite writers and here
he ticks off Dickens, Balzac, Zola also wrote in longhand.
Wolfe himself logs onto a computer only at gunpoint and still
writes in a flourishing script that looks remarkably like John
Hancock's signature.
Again Khargonekar finds himself agreeing with Wolfe,
especially in noting that technology gives us the freedom to
trivialize our precious time on Earth.
"I hope thoughtful people will consider Wolfe's criticism
and find ways of using technology in a responsible manner,
instead of being less wise and less productive," he says.
Khargonekar recognizes that anyone who suggests a pause
in the overwhelming advance of information technology risks
being cast aside as a Luddite, even for the most warm-milk
criticism. (In i9th century England, a group of artisans
known in history as the Luddites protested the industrial
revolution by destroying machines. Today, anyone who whis-
pers any qualms about technology is immediately spat upon
as a Luddite.)
Wolfe has built his half-century writing career on a founda-
tion of infuriating the status quo and so he doesn't mind the
occasional "Luddite" or "mossback" tossed his way. "The Lud-
dites showed their ignorance by destroying the new machines,"
Wolfe says. "Modern man, in his wisdom, has only to increase
his production and speed up his life by ignoring them."
As an engineer, not a social critic in vanilla ice-cream suit,
it's not Khargonekar's nature to ignore technology, but he
does nod at the concerns voiced by Wolfe and others.

"What Wolfe is saying is deeper than that," Khargonekar
says. "Is technology really making us wiser people and truly
productive people? The whole notion of information over-
load and connectivity are significant issues. Technologies
are neither good nor evil. It depends on how we use them.
Consider nuclear technology. We bombedJapan, but France
is getting 80 percent of its energy from nuclear power. Auto-
mobiles come with a cost to the environment, but they made
people free. It all depends on how we use it."
In a world in which a few keystrokes and a search engine can
help us find exactlywhat we are looking for, we may miss finding
the things we didn't knowwe were looking for. The serendipity
of turning a newspaper page and falling into a fascinating abyss
of information might be lost in the newworld order.
As the newspaper goes the way of the dodo and the Edsel,
readers construct facsimiles by plugging a list of interests
into a search engine. They then get all the news they want of
celebrity sightings and the victories of their favorite sports
teams. Few people put "starvation," "injustice" and "bigotry"
into their search engines, and so this technology that can
bring us closer together can also end up distancing us from

one another. Itwill be possible for someone to consider them-
selves well informed after all, they "read a lot" and go
through life without ever encountering anything to upset or
outrage them. One of the functions of journalism is to "com-
fort the afflicted and afflict the comforted." If the comforted
choose to cocoon themselves only in comfort, will there ever
be change or outrage or cries for social justice?
And this is one of the things that most worries Khar-
gonekar about the next generation, which is suckling at the
bosom of new and overwhelming information technology.
Will the next generation become a society that bows before
technology, allowing it to lead? Or will it take the lead?
Technology can be used to help construct productive and
useful lives. Beyond that, there might be ways to unlock tech-
nology's potential to make us more human, to help us become
more compassionate and social. Technology can help us em-
brace the flesh and blood rather than celebrate and perpetu-
ate the synthetic humanity online.
"I do see an optimistic side of the coin," Khargonekar says.
"When you enter a search term and get a thousand results,
you will see things that you never expected. There is still the

20 www.thefloridaengineer.eng.ufl.edu



possibility of serendipity there." The link structure of the
Internet also allows readers scientists and engineers, in
particular to find citations instantly, instead of trolling
library stacks, looking for orphaned, dusty volumes.
But the pessimistic side of the coin has to do with trust.
"The concern that I have is that young people have lost the
ability to tell good information from bad," Khargonekar says.
"I ask librarians,'How are you going to teach students what's
reliable and what's not?' The great thing about books is that
what you are reading is most likely true. But in the age of the
Internet, everybody's a publisher."
Indeed. The Internet has democratized the media to a
large extent, allowing all sorts of geniuses-with-ideas to have
a forum. Not since the days of the colonial press has there
been such an even playing field. To stand up to media mo-
nopolies a decade ago was a futile mission on par with tilting
at windmills. Today, a Web address and an idea are all you
need to become a publisher.
But of course there is a downside. Even a moron can till 40
acres of cyberspace and fill readers' heads with lies and igno-
rance. Yet to many students, a blog carries the weight of a ma-












jor news organization's Web site. "When the New York Times
publishes something, I know that great thought has gone into
that article before I saw it," he says. "A blogger can do and say
whatever he wants and some students may believe him."
Time, that thing we have the least of, will help us sort it
all out. "There is real balance over time between the wisdom
of crowds and wisdom that arises from long, deep expertise,"
Khargonekar says. "Eventually I anticipate we will achieve
some sort of balance. The wisdom of crowds will never re-
place Einstein. The wisdom of crowds has something to tell
us about total human experience and the total human view.
And that brings these questions into sharper focus."
Of course there's no one "right answer" because there
are so many questions. We haven't even thought of all the
questions yet.
And that's what invigorates Khargonekar as he prepares
for re-entry into his teaching orbit. "I want students to be
deeply aware of this connection between technology and so-
ciety," he says.
When he walks into the classroom that first day, the sky
will be full of questions.

It's unpredictable. No two patients are guaranteed the same
quality of care on any given day. A clinic waiting room can be-
come packed at any moment, overwhelming an already stressed-
out health care staff. A seemingly minor error can be deadly.

(ALL THE FACTS And that's exactly where engineering can help health care.

HEALTHCARE) ity, safety and productivity of health care delivery by bring-

ing these fields and disciplines together," said Proctor Reid,
director of programs for the National Academy of Engineer-
ing and study director for the committee that authored the
Building a Better Delivery System report.
Reid can list countless areas where engineering approach-
es could improve health care. For example, hospitals might
be making strides in adopting information technology for
things like electronic patient records, but how about using IT
and systems techniques to improve clinical operations?
"Progress has been very slow, and, I think it's fair to say,
disappointing," Reid said. Yet he pointed to "islands of prog-
ress" like Vanderbilt University's health system.
During a 2008 workshop on using systems engineering to
improve traumatic brain injury care in the military health sys-
tem, Vanderbilt professor Dr. William W. Stead, who also is
the Vanderbilt University Medical Center associate vice chan-
cellor for strategy and transformation, presented a case study
that should have hospital administrators taking notice.
Stead proposed hospitals shift from "expert-based prac-
tice" to "system-supported practice," which, of course, uses




engineering to improve patient care. In this case, patients on
ventilators need complex, specialized care and are prone to
many life-threatening complications. A systems approach,
Stead theorized, could tackle the problem.
"The idea behind system-supported practice focuses on the
system's performance; teams of people, a well-defined process,
and information technology tools work in concert to produce
desired results consistently," Stead wrote in his case study. The
experiment focused on intensive care units and was based on a
design that could be implemented in 45 days or less.
Stead said a major breakthrough in the development of the
system-supported practicewas the "process-control dashboard."
This shows a patient's status as a set of red, yellow or green lights,
using a line for each patient and a column for each element of
the standardized practice. A green light means everything is as
expected, yellow light means action must be taken but there is
still time to do so, and a red light means take immediate action.
One reason the Vanderbilt system ended upworkingwell, Stead
said, was that it operated as a "closed-loop control," meaning the
output of the system feeds back directly to change the inputs.
He likened the system to the interaction between a ther-
mostat and a furnace. When the thermostat senses room
temperature is falling below the set limit, it calls for heat,
the temperature rises, and the thermostat approaches the up-
per control limit and turns off the heat. If someone opens a
window and changes the inputs to the system, the thermostat
adapts to that change without reprogramming.
"The desired performance is achieved without program-
ming complex interactions among inputs or modifying the
program as inputs change," Stead wrote. "This is what is
needed in health care."

For that to happen, though, hospitals and clinics need to
agree on an end-to-end plan of action and have real-time
measurement to show what is happening and display a pa-
tient's status and how that fits into the plan.
Because, as the report cautions, a run-of-the-mill applica-
tion of engineering just won't do. Hospitals are more compli-
cated than giant retail super-centers, and the human body is
more complex than an airplane.
UF engineers and medical researchers are constantly look-
ing at creative ways to improve health care. The contributions
they are making are patient game-changers that will build on
the work programs like Vanderbilt have done to make the in-
ternal workings flow more efficiently.
Dr. Paul Carney, director of the UF Epilepsy Research
Laboratory, is himself both a neurologist and biomedical en-
gineer and teaches in the medical school and College of En-
gineering. He sees endless opportunities to meld engineering
with medicine to improve health care.
Epilepsy is a seizure disorder that affects o5 million people
worldwide. An estimated 25 percent of people with the dis-
ease aren't helped by drug therapy. In five to io years, Carney
hopes to be able to offer them a tiny device that will be im-
planted in their brain and deliver signals to prevent seizures.
In working on that neural prosthetic idea, Carney recognized
it needed a specialized, engineering/medical approach.
"I realized we were really doing systems biology," Carney said.
"We do strive to combine experimentation with computation
around the system, in this case the epilepsy system. We con-
stantly bump into having to understand the brain as a system."
"Systems thinking allows us to at least ponder how we can
do things better," said Hartman of the Industrial & Systems
Engineering Department. "I think the more people you bring
into this arena to ask these questions is a healthy thing."
Or consider associate professor Benjamin Lok's Virtual Pa-
tients Project. In a twist on video game technology, it allows
medical students to examine and relate to life-size patients
and learn everything from bedside manner to better diagnos-
tic techniques. Aside from appearing a little wild-eyed, the

virtual patients are surprisingly realistic, and they can actu-
ally be more effective than human actors when it comes to
stimulating patient/doctor interaction. A virtual patient, for
example, could show symptoms an actor couldn't fake, such
as different pupil sizes.
Carney said UF is particularly well-positioned to foster the
engineering/health care partnership because the College of En-
gineering and medical school are physically close, and faculty are
willing to work across disciplines. One course, BME 6oio, links
engineering students with a preceptor in the medical school, and
the student comes up with a solution to a problem. That course
has spawned real-life medical innovations such as a device that
could detect air in a premature baby's abdomen before deadly in-
fection set in. Another student came up with a hand-held brain
monitoring system for intensive care patients that could tell a
nurse whether a patient was asleep, awake or having a seizure.
"There are a lot of problems out there, and I think the solu-
tions are within reach," Carney said. "A systems approach is
great because it forces people to interact. We have to meet in
the middle and try to leverage each other's expertise."
National Academy of Engineering member William Pier-
skalla said a systems approach is most useful on the operations
side, helping countries like the United Kingdom deliver effec-
tive and efficient dialysis treatment.
"Basically, what systems engineering is pretty good at is
handling waste or inefficiency," said Pierskalla, a retired engi-
neering professor from the University of California Los An-
geles and Wharton School at the University of Pennsylvania
who's still active in engineering research. "But health care has
been slow to adopt it, as well as a lot of IT in general."
With a 2009 economic stimulus package that earmarked $19
billion for health information technology and a spirited national
health reform debate brewing, timing could be perfect for more
systems engineering to be woven into the health care fabric.
"We just have been disappointed that we haven't been able to
move this further along," Reid of the National Academy of Engi-
neering said about incorporating more of a systems approach to
health care. "But I'm optimistic." o

Van Leer Peck (M.S.

first woman to earn
a Gator Engineering

1962, Life magazine
featured her as one
of the promising

on to a successful
career in both industry
and academia. Today
she serves on the

goals. Hemp also recruited female undergraduates majoring
in math and chemistry.
The success of the College's effort was demonstrable: In two
years, the number of female students in the College rose from 26
to 87. By 1980, 13 percent of undergraduate engineering students
were female. The first female faculty member came onboard in
1967, followed by the first female tenure-track professor in 1975.
In 2004, 94years after the College was established, Dean Pramod
Khargonekar appointed Cammy Abernathy as associate dean for
academic affairs, the firstwoman to hold any type of dean position
within the College. He then appointed Jennifer Curtis as chair of
the Department of Chemical Engineering in 2005 and Angela
Lindner as associate dean of student affairs in 2008.
Female enrollment, however, hasn't skyrocketed: With stu-
dents in most disciplines ranging from 13 to 35 percent female
nationally, engineering is a long way from parity.
"When I was at MIT, we had 17 or 18 percent women stu-
dents. It's not much better nationally now," Abernathy said.
"The numbers across the country have hit a plateau."

To explain the plateau, experts point to variety of factors, from
the structure of high school science and math classes to the low
number of tenured female professors. Among the theories:

classes don't always suit girls'learning styles, which may cause
girls to lose interest. "Bad teaching drives a lot of high school
girls away from careers in science and engineering," said Bar-
bara Hughey, an MIT alumna who is now associate director
of the Institute's Women's Technology Program. The pro-
gram brings high school girls to MIT over the summer for an
intensive introduction to engineering.
National solutions: "In middle school and high school, we

age, sometimes treat them more like daughters than equals.
"I'm just going to take it head-on," Peterson said. "Part of the
reason I wanted to be an engineer is because it's a challenge."
Peterson came to UF with a scholarship from SWE, a na-
tional organization founded in 1950, when women had to fight
for a seat in all-male engineering colleges. She's now president
of UF's chapter, founded in 1959 and revived when UF began a
concerted effort to recruit women to engineering in 1972.
Former associate dean Gene Hemp directed the push to en-
roll more women.
"We just felt it was the right thing to do," Hemp said. "I
started by getting all of the female students together in a con-
ference room to talk about what could be done. The bad news
was, we all fit in avery small conference room."
One of the first problems Hemp identified was that women
were being discouraged from careers in engineering not by their
parents, boyfriends or male professors, but by female teachers.
"We had manywomenwho said their female chemistry or math
teachers told them engineeringwas a man's field," said Hemp,who
is alsoUF vice provost emeritus.
He encouraged those students to reach out to female high
school students, telling them not to be dissuaded from their

as the ninth chapter
in the country, it
initially represented
seven women in en-

gineering, according
to a 2003 history by
Vice Provost Emeri-
tus Gene Hemp.
The first female
engineering gradu-
ate earned a bach-
elor's degree in 1948.
The first woman to
receive an engineer-
ing graduate degree
at UF, Maryly Van
Leer Peck, earned
a master's in 1955
and a Ph.D. in 1963.
She gave birth to
four children during
the course of her
studies, and she
was featured in Life

magazine in 1962 as
one of the promising
young women of
her generation. Peck
worked as a senior
research engineer
for Rocketdyne
before working in
academia in Guam,
Arizona, Maryland
and Florida.
In 1972, SWE was
revived as part of a
concerted effort to
recruit more women
to UF's program.
The organization
now offers mentor-
ing, social activities
and networking to

women, along with a
few male members.
At the jubilee,
SWE members will
have a chance to
meet the alumnae
who started it all.
"We want every-
body to know about
the women who went
before them," Hemp
says. "They should
understand they
are standing on the
shoulders of giants."

For SWE Jubilee

need to grab their attention so they see the relevance of sci-
ence and math to what they want to do," said Hughey, whose
daughter is a high school sophomore. Programs like WTP
help by giving girls the hands-on experience their high school
curriculum may lack.
Gator Engineering solutions: SWE reaches out to middle
school and high school girls with two annual programs. In
the first, engineering students visit local schools to give girls
a better picture of the dynamic, collaborative nature of engi-
neering careers. In the second, high schoolgirls come to cam-
pus for hands-on lab experience.

2. A LACK OF FEMALE PROFESSORS as mentors and role
models may discourage female students. In 2008, just 12.3
percent of engineering faculty were female, according to the
American Society for Engineering Education. The shortage of
female mentors might make a young woman's college experi-
ence more difficult, and it may discourage those women from
pursuing careers in academia. Abernathy says her experiences

at Stanford and MIT made her doubtful she would ever teach.
"When I looked at the faculty, it didn't look like an envi-
ronment where I could fit inverywell," she said.
National solutions: Hemp suggests the economic downturn
may also come to the rescue: When job offers for engineers
with bachelor's degrees aren't as plentiful or lucrative, more
students opt to further their education with master's degrees
and Ph.D.s. It's possible this could lead to more talented fe-
male students going into academia.
Gator Engineering solutions: Since 20oo, Khargonekar has
increased the number of female faculty in the College by So
percent. And the Florida Institute for the Development of
Engineering Faculty prepares graduate students for careers in
academia by giving them an inside look. Students learn about
academic job searches, create resumes and craft research and
teaching statements.

may try to protect bright young students from the same ex-
perience. That's what happened to Sabrina Parra, a civil en-
gineering senior from Miami, whose high school teacher
tried unsuccessfully to steer her away from engineering.
"She said it was probably not going to be a good field for

me," Parra said. "I found out later she had been in engineering
and had switched to teaching."
National solutions: Outreach programs such as the Web site
EngineerGirl.org, launched by The National Academy of En-
gineers in 2000, lets teenage girls explore career options and
connect with women in the field.
Gator Engineering solutions: When female engineering stu-
dents arrive at UF, SWE matches each of them with an upper-
division mentor in her field. The mentors coach new students
through the program with study groups, test review sessions,
social support and networking.

4. ENGINEERING MAY SUFFER from an image problem.
A 2003 study from the University of Michigan showed that
girls who excelled in science tended to choose careers in bio-
logical sciences because of their perception that engineering
and math-based sciences were "less people-oriented." Girls in
the 17-year study cited wanting to help people as a reason for
choosing the so-called "soft sciences" over engineering.
National solutions: From biomedical to environmental
engineering and everything in between, the perception that
engineers don't help people just doesn't stand up to scrutiny.
But engineers need to do a better job spreading the word,
Abernathy says.
"A young person's perception of what we do doesn't take
into account the collaborative nature of engineering today,"
she said. "You're not working in a lab all by yourself trying to
figure out how to make widgets. A lot of engineering is about
making people's lives better."
The Gator Engineering solution: The awed expressions of
the kids at UF's annual Engineering Fair offer ample proof of
UF's contribution. When elementary and middle schoolers
see the submarines, satellites, robots and electronic games
that UF students create, engineering's reputation as a cold,
theoretical discipline is dealt a death blow.

How will we know when we've succeeded in paving the way
for women in engineering?
"The only way to tell if our job is done is if the percentage
of women in the student body goes up, when we get to some-
thing that looks like parity," Hemp said.
The good news, says Abernathy, is that diversity in one
area, be it race or gender, helps diversity in all areas. As one of
a few female students in her department at Stanford, an experi-
ence she likens to "being in a men's locker room or a fraternity
house," Abernathy found camaraderie with a male African-
American professor who could relate to feeling like an outsider.
"If he hadn't been there, I don't know how I would have
made it through," she said.
While the female students of today are highly unlikely to be
singled out for ridicule as Lindner was, the associate dean still
hears tales of internships punctuated by daily catcalls from male
co-workers. When young women do encounter sexism, however,
they have a wider support network than in years past. And that
network isn't exclusively made up ofwomen. It's important to re-
member, Lindner says, that for every male engineer or professor
who makes a female engineer's life harder, there are more who
have genuine commitment to diversityin the field.
"I could have walked out of college with the message that
white males were my enemy, but that's not fair. We can't ste-
reotype them back," she said. "You have to give everyone the
opportunity to do the right thing."

Geeky confessions, milk cartons and a corporate dream

Even now, with a little hindsight and maturity in her personal rearview,
she laughs at her own precocious coed moxie an audacious proclamation
to the Dean of the College that he tells her he has not yet forgotten.
"I told him I wanted to be CEO of Procter & Gamble," laughs Silva,
25, a native of Brazil and a 2007 industrial and systems engineering graduate. "He
tells me he still remembers that. I'm going to work hard so I don't let him down."
Today, through the power of her own determination and some forceful goal-
setting, Silva is well on her way to making that dream a reality, even as she says she's
backed off a tad on her own definition of success. Now in her second year at the
Cincinnati-based corporate giant, she's traveled as far away as China andJapan where
she's conducted market research interviews with foreign mothers on the right kind of

Pampers-brand diapers best suited for
their babies and their culture.
It's not engineering, says the
perpetually upbeat Silva, but she's
using concrete skills she learned in the
College the problem-solving, critical
thinking and analysis to put her own
imprint on marketing P&G products.
"It's the little things," she says with
a believable sass. "If the flavor of your
toothpaste changes, that sucks. It's very
personal. At P&G we put a lot of thought
in you getting the best quality. I get to
touch the lives of millions of people.
"Some people like to do community
service, some people like to join civic
groups. Props to them, I think that's
great work," she adds. "To me this is one
way I find to help others by giving
them products that help. P&G was the
first company to ever put fluoride in
toothpaste... and it improves smiles and
lives in small but meaningful ways. I
thought'That's amazing.'"
Silva also became a cheerleader in her
own right of the P&G brand, ticking
through a litany of well-known groom-
ing and household tools like a spokes-
woman badly in need of some airtime.
"I'm Hispanic and we love scents,"
she confides, noting at age 15, the family
moved to Miami. "Like the way I mea-
sure clean is through smell. Other people
look for more visual cues the brighter
the white. It's very dorky."
She is loyal to Crest toothpaste and
her Olay face cream "I use the low end
stuff because I'm not that old. I don't
need wrinkle protection yet."
And don't forget the Febreeze
candle, the Swiffer and her yummy
Olay Ribbons (body wash). "It's a little
pricey but it's totally worth it. I'm lazy
and I forget to put on moisturizer, so
this really helps with that."
Spoken like a true girlygirl but one
who is driven enough to have already
crafted her own glamorous bucket list that
takes her to the far corners of the conti-
nents and back she's crossed off"climb
Great Wall of China" but still hopes to
"sled down the Olympic luge track in Lake
Placid, N.Y. at 90 mph." Then there's
"pet a kangaroo," and stroll the Taj Mahal
barefoot, along with attending the Cannes
Film Festival and a real masked ball.
She lives her life surrounded by small
motivational tools keeping her focused
as she crafts some creativity into her
consumerism. She dreams in practicality.
Driving to work, Silva favors silence
over music so she can ponder the day
ahead. The background screen on her
cell phone reads "Push Yourself" and
she's an avid reader of both Psychology
Today and Scientific American. Every
Sunday, she reads postsecret.com, and
honors her homeland with indulgences



of Haagen-Dazs' Passion Fruit and
Rum Raisin ice creams "because they
remind me of Brazil."
At her ioo-year-old apartment, her
bathroom holds a cheeky secret: "I have
three plastic bracelets I hang from my
shower head I wore at a nudist resort.
I keep them to remind me of how free
spirited I felt. It's not something I had
ever done or will do again, but they
remind me I need to always push myself
outside of my day today comfort zone."
But it's her family and a road trip with
the Silva crew to a Parmalat milk factory
in Paraguaywhen she was ii that seeded
her fascination for product packaging. It's
a geeked-out confession, her wonderment
at something so benign as a manufactur-
ing assembly line for milk that leads her
to spill the details of her career path.
"I was just fascinated by all those little
boxes getting folded by robot machines,
all put into packages and trucked without
humans ever touching it," she recalls.
"That's what makes me so excited by con-
sumer goods. You look at a tube of tooth-
paste and you never think about what goes
into making that. At Parmalat, I realized
there is a lot of magic that happens behind
everyday products and that to me is so
beautiful, so seamless to the end user."
She's been accused of drinking the
P&G Kool-aid, but says the company's
management philosophy of investing in
people, cultivating their potential and pro-
moting fromwithin is in line with her own
social consciousness view of the world.
"I love what it stands for, what it does,
the people leadership, ownership, pas-
sion for wining, integrity. Their values
and my values are very much in line,"
she says, adding that adjustment to life
in the Midwest has been easy, even for
someone who grew up in South America.
She allows she's a long way from home,
but she's finding comfort in creating
things that are used across the globe.
"I want to have an impact there," she
says of her goals at P&G, which include
making good on what she told the Dean,
though she sees herself a little wiser now.
"It's not about being CEO," Silva
says. "I look at this like dropping a
pebble in a lake you get ripples. The
higher you drop the pebble the farther
away the ripples are going to go. The
higher up I go in a company, the more
ripples I can make every day." o

complete,He led the borescope inspection
efforts which found Thermal Control System
(TCS) blankets out of configuration and
capable of blocking the FRCS vent ports.
Finding the cause for the over-pressurization
event prevented the need to remove the FRCS
to perform a more invasive investigation. With
the FRCS still in place, the TCS blankets were
capable of being correctly re-installed. If the
FRCS had been removed from Discovery, USA
would have missed the vehicle rollout milestone
from the Orbiter Processing Facility (OPF) to the
Vehicle Assembly Building (VAB) and possibly
delay the scheduled launch date.
Currently he is performing Systems Engineer-
ing work for NASA at the Kennedy Space Center
for the NASA Constellation Program.
His second son, Gabriel, was born on July 4th,
2008. Michael, his first, son was born in 2006.

began an engineering practice in Orlando, Fl.
with colleague, Jamie T Poulos. After work-
ing together at both the South Florida Water
Management District and a local planning and
engineering firm, the two became LEED Accred-
ited Professionals and started Poulos Brown, LLC
to provide civil engineering and land develop-
ment services in the area. Prior to this, she spent
six months volunteering in Esparta, Atlantida,
Honduras designing a sanitary sewer collection
and treatment system for the community. Poulos
Brown was established as a woman-owned
business with a strong emphasis on community
service and involvement on local boards, includ-
ing the provision of pro bono services to the City
of Orlando for small scale projects.

< Lisa Armbruster, M.S. CCE
was awarded the 2009 UF Foundation Outstand-
ing Young Alumni Award. She is assistant director
of governmental affairs for the Florida Shore and
Beach Preservation Assoc. She worked on a year
long beach renourishment project for the coastline
of Panama City Beach. After Hurricane Ivan and
other storms, Panama City beach lost about 4
million cubic yards of sand. The project required
dredging offshore sand to restore the beach. This
provided a barrier between the damaging waves
and properties on the shore. Maintenance on the
renourishment of the coastline will continue to pro-
vide protection from future hurricanes and storms.

is an engineering department project manager
at Engenuity Group Inc. He was appointed
to Palm Beach County Water Resources Task
Force. The PBCWRTF was enacted by the

missioners under Resolution No. R-2008-1810,
adopted on October 7, 2008, with the mission
of tackling regional water resource issues such
as future water supply, conservation, wastewater
treatment, and water reuse.

Marlin Scott Clark, B.S. MAE
graduated high school early at the end of his
junior year. He attended Hillsborough Com-
munity College for two years to attain his
associate in arts degree. He says he's always had
an affinity for creating things and understanding
how everything worked and how he could make
it work better. When he was six, his parents
bought an above ground pool and the family
was leveling sand to assemble the pool on. He
says he knew there was an easier way to get the
job done so he went to the shed and built a drag
by him self using a hammer and nails with short
2x4's, cut plywood and rope.

As Dean Khargonekar steps down, he leaves a legacy of dedication, passion and excellence

I n this issue of The Florida Engineer, we pay tribute to the
many contributions Dean Pramod Khargonekar made in
his tenure as dean. The support and partnerships formed
mirror the vision set forth by Dean Khargonekar begin-
ning with the establishment of the J. Crayton Pruitt Fam-
ily Department of Biomedical Engineering. The endowed
department provided by Dr. Pruitt and his family provided
a spring board for a number professorships and chairs to be
provided by alumni and industry partners such as Bellsouth
and Intel Corp. We are fortunate to have a leader with a
firm vision for the College's future. Friends and alumni
have responded with numerous scholarships, fellowships
and research support, making his vision a reality. Increased
graduate student enrollment, stellar faculty hires, centers and
institutes and innovative research are the result trust and be-
lief in Dean Khargonekar's mission.Jumping io spots in the
US. News and WorldReport rankings from 35th to 25th overall
is just one illustration of his dedication and hard work.
The College has established two funds to honor Dean
Khargonekar's leadership and passion for excellence.
Through the generosity of alumni, faculty and students the
College has established the KhargonekarJunior Faculty
Award and the Dean's Excellence Fund. The Khargonekar

Junior Faculty
Award reflects
his belief that
investing in faculty
will enhance the
College's ability to
respond to greater
educational and
research opportu-
nities. The Dean's
Excellence Fund
is an endowment
that will generate
resources in perpe-
tuity allowing future deans the ability to respond to the many
emergent needs and opportunities sure to arise. We hope you
will take a moment to look online at the Khargonekar award
and Dean's Excellence Fund brochure at www.development.
ufl.edu and make a gift honoring his many accomplishments.
We are grateful for Dean Khargonkear's vision and leadership
and to the manywho have already invested so we can pay tribute
to his passion and desire to succeed. We look forward to reaping
the rewards of his leadership for many generations to come. o
