I am a stable isotope biogeochemist who focuses on the sources and fates of methane in marine and freshwater environments. At the USGS I am using analytical chemistry methods (e.g., laser spectroscopy, mass spectrometry, and gas chromatography) and fieldwork to better understand the transformation of methane-derived organic matter.
