Through the research program, Dwelle will spend June through September at Sandia National Laboratories in California. Dwelle will work with Khachik Sargsyan (a U-M alum with a doctoral degree in applied mathematics) on Dwelle’s project titled, “Uncertainty quantification in seasonal flooding and methane emissions of the Amazon basin.”

“The overall problem from an environmental perspective is that methane emissions from wetlands make up a large amount of all natural methane emissions. The Amazon basin has seasonally-flooded wetlands (due to the wet/dry seasons) which contribute a significant proportion of global wetland emissions,” Dwelle says of his project. “However, estimates of the amount of methane emitted in the Amazon are hugely variable – from 7 to 142 teragrams per year — and my work will be towards quantifying just how much uncertainty there is in these estimates using computer models. The approaches being used also allow us to infer which physical processes have the greatest impact on methane generation for this highly complex natural system.”

The SCGSR program provides supplemental awards to outstanding U.S. graduate students to pursue part of their graduate thesis research at a DOE laboratory in areas that address scientific challenges central to the Office of Science mission. The research opportunity is expected to advance the graduate students’ overall doctoral thesis while providing access to the expertise, resources, and capabilities available at the DOE laboratories.
