David Wark earned an Environmental Science B.S. degree (2019) with additional coursework in organic and analytical chemistry. He has five years of experience with the study of emerging contaminants in surface water, fish, and mussels encompassing sample collection, extraction, and analysis by LCMS instrumentation using targeted and non-targeted methods. He has four years of experience analyzing LCMS data for the detection and confident identification of emerging contaminants using tandem mass spectrometry and modern online spectral databases.
