Joe von Fischer, a climate change scientist, is a professor in the Department of Biology who studies how processes on the land surface affect the atmosphere's greenhouse gas composition.  Joe’s lab maintains two primary research areas.  One is the study of how natural ecosystems exchange methane, nitrous oxide and carbon dioxide with the atmosphere.  These studies use biogeochemistry, microbial ecology, soil physics and stable isotopes, among other approaches.  The other area is in collaboration with the Environmental Defense Fund to find natural gas leaks in urban distribution systems around the country.  Work in this area is a collaborative effort with the natural gas industry, attorneys, scientific instrument manufacturers, NGO's, state and federal policymakers and other scientists.  Current funding in the von Fischer lab is strongest for this urban work, but students are invited to apply to advance their studies in either area.
