Dr. Covadonga (Cova) Arias
Dr Covadonga Cova) Arias (photo. right) and Brandon Hockema
(photo, left) headed to Alabama, where Cova has accepted a
position at Auburn University as Assistant Professor of Microbial
Genomics in the Department ol'Fisheries and A lied Aquacultures.
Cova's assignment will be 95% research and 5% teaching. Her
research will focus on fish pathogens, particularly pathogens of
catfish and tilapia.
Cova, a native of Spain, came to CREC in January 1999 to work
with Dr. Jackie Burns. She has a bachelor's and Ph D from the
University of Valencia, Spain. Her Ph.D. research involved the
study offish pathogens She also worked at an agricultural research
center in Spain on potato pathogens prior to coming to CREC
In Dr. Burns' laboratory, Cova worked on abscission studies to
facilitate the development of mechanical harvesting technologies.
Areas included the evaluation of abscission, or "fruit-loosening"
agents, to aid in mechanical harvesting and investigations into the
cellular and molecular changes that occur in citrus during the
abscission process. Cova was also involved in molecular studies
ofpeciinesterase, an enzyme in citrus juice that causes such effects
as juice clarification and gelation of concentrates. In addition, she
and Dr. Burns have worked with Dr. Mickey Parish on identifying
spoilage yeasts in orange juice.
Cova's will have a lab in the USDA Aquatic Animal Health
Research Laboratory on the Auburn campus, where she started
work on April I.
