Dr. Townsend-Small has a BA from Skidmore College and a PhD from the University of Texas at Austin and is currently an Associate Professor at the University of Cincinnati. In addition to her work on using stable isotopes to assess sources of methane in groundwater, she also has ongoing research assessing methane emissions from the natural gas supply chain as well as determining whether climate warming and changing hydrology will result in increasing emissions of methane from Arctic ecosystems and lakes and reservoirs.
