Our lab is interested in alternative forms of micobial respiration, especially those involving sulfur and iron, with a focus on discovering novel modes of respiration in "extreme" environments such as acid hot springs, hot mud volcanos, and subsurface petroleum resevoirs, as well as in more conventional environments such as deep sea sediments. We use techniques from mechanistic enzymology, microbiology and molecular community analysis to understand both the way that anaerobic respiration works and the way that it affects the geology of the earth.
