Brief synopsis of current research:
My work focuses on identifying the consequences of anthropogenic stressors on natural systems. The main emphasis is on the sources, pathways and fate of persistent pollutants such as organochlorine pesticides, polychlorinated biphenyls (PCBs) and trace metals in aquatic environments. I am presently looking at the potential for ecosystems in cold climates to retain and biomagnify semi-volatile organochlorine compounds like PCBs and pesticides. Another component has involved an examination of trace metal release from terrestrial environments to surface waters in response to logging and smelting practices. Methods include a combination of field analysis and modeling approaches. My work encompasses a range of biological and chemical limnology, land-water interactions, biogeochemical cycles, and water quality issues.
