Research

Research Areas: Global cycles of carbon, nitrogen, and water; carbon cycle-climate change feedbacks; energy production and greenhouse gas emissions; stable isotopes and radiocarbon dating

My current research explores the sources and fluxes of methane, a very powerful greenhouse gas. My group is investigating whether the transition from oil and coal to natural gas as an energy resource will result in increased emissions of methane, with ongoing research in Ohio, Texas, and Colorado, as well as whether climate warming and changing hydrology could enhance methane emissions from lakes, with ongoing research in Lake Erie and the Arctic. My approach includes measurement of carbon and hydrogen stable isotopes as methane source indicators. Explore my publications.
