Catfish farmers continue to identify disease as the main problem for their industry. My research focuses on Microbial diagnosis of bacterial catfish pathogens: detection and molecular epidemiology Identification and characterization of genes associated with virulence in catfish pathogens. Analysis of microbial communities in aquaculture setting.
A second area of research is related to food safety in oysters.

We are currently working on:

1. Vibrio vulnificus coldshock response under refrigeration conditions
2. Evaluating the efficiency of postharvest treatments in oysters
