Dr. Srikumar’s research focuses on understanding how pathogenic bacteria survive and proliferate in poultry meat and environment. Studying the pathogen-food interactions at a molecular level will allow deep insights into how pathogenic bacteria alters its metabolic and regulatory profiles during adaptation to the different poultry environments. To this end, we will use different nucleic acid sequencing-based and other molecular microbiological assays on Salmonella Typhimurium (and other select serotypes) as model organism (s). Our goal is to develop data that will futuristically aid development of novel technologies aimed at making food safer.
