The overall aim of my research is to develop effective intervention strategies for controlling foodborne pathogens by characterizing their pathophysiology and interactions with the environment and the host. Built on the principle of “farm-to-fork” food safety, my current research focuses on four broad areas, namely (I) reducing pathogen survival in poultry gut, (II) controlling the persistence of foodborne pathogens in processing environment, (III) inactivation of pathogens in food products and (IV) reducing the infection process of foodborne pathogens in humans.
