Research Interests

Aquatic Microbial Ecology, Microbial Physiology, Biogeochemical Cycling

I am interested in understanding how the behavior and physiology of microorganisms influences ecosystem function and global biogeochemical cycles. My work spans scales from single cell physiology tracking cell-specific uptake rates of environmental metabolites, to ecosystem scale analyses of microbial community composition, diversity and gene transcription, and geochemical fluxes. My research program is primarily undergraduate student research driven through the hands on courses I teach. 

Courses Taught

BIOL165— Field Studies in Tropical Biodiversity and Conservation—Penn Global Seminar in Costa Rica

BIOL375— Microbial Diversity & Pathogenesis

BIOL376— Microbial Diversity & Pathogenesis Laboratory

BIOL464— Field Studies in Aquatic Microbial Ecology
