Mechanical Technology
New Methods Geared Toward Profits, Longevity

tractors and tillers. Now Dr.

ability to build, develop,
discover and change lives using engineering.
Agricultural engineering was the only
(college) major that allowed me to learn
cutting edge engineering skills and apply
them to agriculture," Ehsani said.
Ehsani said his goal is to bring new and
advanced technology to Florida citrus
production and agriculture. As the assistant
professor of agricultural and biological
engineering, focusing his research on
mechanical harvesting and precision
technology, Ehsani works to acquire the
abilities to do just that by helping growers
optimize their resources and make better
management decisions.
"My overall goal is to make citrus
production profitable and sustainable,"
Ehsani said. "Currently, labor costs account
for a significant part of citrus production.
Mechanical harvesting and automation can
potentially reduce a grove that cost.
Additionally, new precision technologies can

help grove owners make better and
more informed decisions."
His main area of research is related
to mechanical harvesting and
application of precision technology for
citrus production. He has four projects
in citrus mechanical harvesting
including developing a yield monitoring
system for citrus mechanical
harvesters, increasing the efficiency of
the catching frame on citrus
mechanical harvesting equipment,
developing methods for expediting the
canker decontamination process for
citrus mechanical harvesting
equipment. The last is a project on
improvements of machines that pick up
citrus off the ground.

Browning Marks Tenth Year as CREC Director

Browning examines a citrus

In 1996, Dr. Harold Browning
packed up his office in the entomol-
ogy lab housed in Building 7135 and
moved across the street to begin his
new job as CREC Center Director.
His goals for the Center were clear:
Improve communication between
the Center and the citrus industry
by working closely with them in or-
der to better understand their
needs; Increase the effectiveness of

the Center concerning operations by
reorganizing and creating positions
that were needed; Strengthen the
link with Gainesville to make our
needs better known. As Director of
CREC, Dr. Browning has the respon-
sibility for the largest collection of
scientists focused on citrus research
in the world. He is also the state-

Ten years later, he said we've made pro-
gress but there is still work to be done on all fronts.
In his own words:
Q: Looking back over the past 10 years, what ac-
complishments are you most proud of? A: The Center
has accumulated many accomplishments that I am very
proud to be part of. Among these are the recruitment of a
very fine group of faculty and staff that have joined the
Center in the past 10 years. These faculty and staff are
continuing the tradition of outstanding contributions to
their disciplines and to the Florida citrus industry. We
have been striving to keep pace with many changes within
our parent organization, within the
CREC, and within the Florida citrus
industry. Continued communication be- We have b

through retirement and relocation has
impacted our core capabilities and dra- tionshis tha
matically reduced the experience base
upon which we build our problem-
solving approaches. Our challenge has
been to minimize the affects of this reduction in faculty on
our ability to meet our mission. Hiring strong new faculty
and staff are among the ways to offset these losses. An ad-
ditional challenge is keeping pace with the dynamics of the
citrus industry and being able to respond to predictable
and unpredictable directions that the industry has taken.
Q: What is your favorite part of the job? A:I have en-
joyed the opportunity to become familiar with a broad
cross-section of science, engineering and economics that is
associated with our faculty programs. This has been a
stretch well beyond my previous experience and training.
Another of my favorites has been the opportunity to be-

Q: What's next? A: Long-term goals include helping to
chart a future course for the CREC which will extend the
long and strong tradition of the Center. A short-term goal
is to enable the faculty and staff to make progress against
serious new challenges that our clients

Browning graduated from Willamette University
with a bachelor's degree in biology and met his wife,
Nancy, there during freshman orientation. He

Although his goals have changed over the past 10

of wireless sensor networks for citrus production,
the application of electromagnetic induction
sensors for canopy measurement, a system for
detecting and mapping HLB in the grove, and a

available GPS receivers in citrus groves. The
outcome will assist growers to choose the right
GPS receiver and be able to use them more effectively.
Ehsani and his wife, Elizabeth, have two sons, Arman and Nick. Nick, the
younger of the two, likes to play on a small mowing tractor. Ehsani said he
pretends to fix the tractor with a wrench from his Dad's toolbox. Could there be
another agriculture engineer in the making? Stay tuned.
