We are a genetics/microbiology lab studying disease ecology, microbial ecology, and immunogenetics of amphibians and reptiles  We are based at Dominican University of California in San Rafael, CA. Our research explores the microbial diversity and genetics of North American amphibians, reptiles and their pathogens.
