Institution: Oregon State University
Department: CEOAS – Marine Geology

Research Theme: I enjoy studying unique microbial habitats, the microbes in those habitats, and trying to work out what controls their survival in those locations. My goal is to understand how integrated microbiological systems function. When possible, I like to work iteratively with modelers. Developing strategies for accurate estimation of in situ rates of microbial activities in the subsurface related to the carbon cycle. Microbiology of methane hydrates in deep marine sediments and beneath permafrost. Importance of biogeochemical processes in the carbon cycle.
