Marina E. De León

Dsoralia_7I am a doctoral candidate in the Microbiology Graduate Group focusing on chytridiomycosis in amphibians. I received a B.S. in Wildlife Conservation Biology from UC Davis and an M.S. in Biological Sciences from Cal Poly, Pomona.

The amphibian pathogen Batrachochytrium dendrobatidis (Bd) continues to destroy amphibian populations throughout the world. Understanding Bd epidemiology and treatment options are imperative to ameliorating the pathogen’s destructive effects. In the Eisen lab, I incorporate field and bench techniques to explore microbial and molecular Bd treatments in vitro, and I use bioinformatics techniques to analyze Bd dissemination over large scale regions. My current region of study is Central America, but I have also conducted field work on Northern California Cascades frogs and Southern California Western toads.

Research is funded by the National Science Foundation Graduate Research Fellowship Program (NSF-GRFP), the Smithsonian Tropical Research Institute, Panama (STRI) Short Term Fellowship, and the UC Davis Center for Population Biology research award.
