Most of my publications focus on the environmental fate and management of harmful chemicals in aquatic systems. These include identification of bioactive transformation products, characterizing roadway runoff and tire rubber compositions, mass spectrometry of organic contaminants at trace levels, and using high resolution mass spectrometry in environmental systems.   Links to select papers that best represent our research efforts can be found below.
