Description of Research
Summary Statement of Research Interests
The general focus of my research group is environmental biogeochemistry. We are trying to elucidate how bioactive substances influence specific biological processes (e.g., carbon and nitrogen fixation) as well as phytoplankton dynamics (species composition and abundance) in different aquatic systems. To accomplish those research objectives, we study the cycling (e.g., sources, transport, fate, bioavailability) of various trace metals, B-vitamins and mineral nutrients in ecosystems. Another objective of my research group is to establish the impact of anthropogenic processes on environmental quality. We try to apply our results to environmental policy analysis, including issues related to public health.
Research Specialties
Trace metals, organic carbon and nitrogen cycling in aquatic systems
Cycling of vitamins in aquatic systems
Impact of phytoplankton blooms on metal geochemistry
Impact of trace metals and nutrients on nitrogen fixation
Impact of colloids on metals and organic carbon cycling in coastal environments
Impact of groundwater seepage on coastal waters
Isotope geochemistry (stable lead isotopes as tracers of anthropogenic sources)
