Andreas J. Bäumler  Andreas J. Bäumler, Ph.D. is a professor in the Department of Medical Microbiology and Immunology at the University of California, Davis School of Medicine, in Davis, California. Bäumler studies the molecular mechanisms of "Salmonella" interaction with the intestinal mucosa. He is one of the leading researchers in the field of "Salmonella" research and has several highly cited publications on the topic of Salmonella infection, immunity to Salmonella, and the interactions between the host, pathogen and the intestinal microbiota during infection. Bäumler has a B.S. and a Ph.D. in Microbiology from University of Tübingen, Germany. Bäumler is a fellow of the American Academy of Microbiology  and Editor in Chief of the scientific journal "Infection and Immunity." The Bäumler lab studies the human disease manifestations associated with "Salmonella" serotypes such as typhoid fever caused by "Salmonella" typhi and gastroenteritis caused by non-typhoidal "Salmonella" serotypes (e.g. "S". Typhimurium). One focus of Dr. Bäumler's research is to understand why typhoid fever and gastroenteritis differ in the host response elicited at the site where both infections originate, the intestinal mucosa. The Bäumler lab aims to understand what "Salmonella" virulence factors and host factors contribute to the different disease manifestations caused by different serotypes of "Salmonella".
