My research interests are in molecular microbiology, foodborne illness and biodefense, and I have experience working in phylogenetics, quantitative genetics and biodefense research. While working in a biodefense research laboratory, I was involved in the development of rapid detection methods (real time PCR) and using molecular typing (ribotyping and pulsed field gel electrophoresis) for foodborne outbreaks. These methods are useful in foodborne outbreak and bioterrorism investigations because there is a need to identify pathogens and track them quickly. I am also interested in the differences in the pandemic and non-pandemic strains of Vibrio parahaemolyticus. These are areas of research that I have continued while at Kean. My students have researched the use of newer molecular methods (loop-amplified isothermal amplification) for detecting bacteria in food, historical diseases and bacterial transmission in bathrooms.
