Biographical sketch

My research interests relate broadly to biogeochemsitry, including low-temperature geochemistry and geobiology. I am particularly interested in microbe-mineral interactions in the modern and geologic past, as well as soil biogeochemistry, stable C and N isotopes, biogeochemical cycling of nutrients during animal decomposition, and microbial ecology. Additional research interests include symbiotic associations between micro- and macro-fauna in surface and subsurface systems, and modern and fossil bone geochemistry.
