Dan Colman received his Ph.D. from the University of New Mexico in studies of extremophile microorganisms and is a postdoctoral researcher in the Microbiology and Immunology Department at Montana State University in Bozeman, Montana. He is a member of the Biological Electron Transfer and Catalysis (BETCy), an Energy Frontier Research Center. His current research includes using bioinformatics approaches to understand the mechanistic basis for electron bifurcation, an enigmatic energy-harnessing process performed by microorganisms. Dan also has a range of other projects focused on understanding the microbial-geochemical interactions that occur within extreme environments, such as hot springs in Yellowstone National Park, Wyoming.
