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. | |
