My dissertation research broadly focuses on understanding how community level factors affect the transmission and persistence of the fungal pathogen, Batrachochytrium salamandrivorans (Bsal), in terrestrial and aquatic environments. Previous research focused on ecotoxicology and biogeochemistry studies pertaining to radioactive and heavy metal contaminants.
