Mark Skidmore is an assistant professor of geology at Montana State University. Dr. Skidmore’s field research takes him to glaciers in Antarctica, the Swiss Alps, Alaska, the Yukon, Iceland, and Washington. He also conducts low temperature laboratory studies of microbial activity at near freezing temperatures. His current research focuses on the biogeochemical cycling and geomicrobiology of glacier systems and biogeochemical processes associated with geologic carbon dioxide (CO2) sequestration.
