Biography

Key words: environmental pollutants, contaminant monitoring, biodegradation, bioaccumulation, bioremediation, stable isotopes, sedimentary biomarkers

I study distribution, fate, and transport of environmental pollutants in different aquatic environments from small freshwater tributaries to coastal marine ecosystems.  I evaluate removal of pollutants from aquatic systems via adsorption onto sediment and microbial degradation.  Moreover, I study bioaccumulation of these pollutants in ecosystem food web structure.  My research investigates how environmental parameters affect the fate and transport processes of contaminants in aquatic systems and utlizes stable isotopes as a tool.  I am interested in extending current research to explore cost-effective bioremediation strategies for widespread pollutants in the environment.  In addition to the research in environmental pollutants, I also study human-induced changes in natural biogeochemical cycles using sedimentary biomarkers.
