Research statement

Building new devices to measure electron transfer from living cells, isolating cool organisms from deep underground, and working carefully through electron transfer pathways one gene at a time. Whatever microbial physiology, anaerobic microbiology, bioelectrochemistry, and geochemistry have in common, that's usually what we're doing.
