Biographical Sketch

I am an Associate Professor in the Department of Environmental Science and Technology (ENST) within the College of Agriculture and Natural Resources (AGNR) at the University of Maryland College Park (UMCP). My professional career, beginning ~1990, has involved integrating fundamental and applied research to better understand and mitigate the sources, fate, and ecological effects of contaminants in the environment. Since starting with ENST (beginning 2008), I also incorporate teaching and mentoring of graduate and undergraduate students as essential activities for transferring core ecotoxicological ideas to succeeding generations. I teach introductory to advanced courses in Environmental Toxicology and Ecosystem Health, advise MS and PhD students, mentor undergraduate researchers (individually and within groups), and perform research within and beyond the Chesapeake Bay Watershed on a variety of contaminant issues including (but not limited to): endocrine disruptors, metals (Hg, Cd, As, etc.), organics (PCBs, PAHs, TCDDs, OC pesticides), and microplastics. I collaborate with state and federal agencies, non-profits, commercial entities, and diverse academic colleagues from four continents.
