Research

My lab is interested in the zoonotic pathogen Salmonella enterica. Salmonella is an important pathogen of large animals and is a leading cause of bacterial foodborne gastroenteritis in humans. Our studies aim to determine how Salmonella colonizes the intestine of susceptible hosts and how it is transmitted between individuals. Please see our website for more information.
