I develop targeted and non-targeted analytical chemistry methods — and the data-processing tools and workflows behind them — to detect chemicals of emerging concern in the environment. My work pairs high-resolution mass spectrometry with non-targeted analysis to tackle problems ranging from PFAS in drinking water to rapid emergency response.
I’m a Physical Scientist (GS-14) at the U.S. EPA’s Office of Applied Science and Environmental Solutions (OASES), where I lead research that turns complex mass-spectrometry data into actionable identifications of unknown compounds in environmental media.
