Dr Khan’s research targets certain aspects of food safety and poultry production through the application of molecular tools for understanding host-pathogen interactions. Dr Khan works as a postdoctoral fellow in Prof Kapil Chousalkar Research Lab at the School of Animal and Veterinary Sciences, The University of Adelaide. Dr Khan uses molecular microbiology tools to understand the role of zoonotic pathogens in food safety.
