Get to know Dr. Singh


Dr. Singh is a food safety microbiologist by training, and his core area of research focus is the development of rapid methods for the detection of foodborne pathogens. His laboratory focuses explicitly on developing methods for the specific detection of virulent strains of Shiga toxin-producing non-O157 Escherichia coli and Salmonella. His second area of research interest is the development of rapid methods for seafood species identification.
