Research in my laboratory is focussed on the exposure and effects of chemicals in aquatic ecosystems. Research is in both the field and the laboratory. For field research, we have a 21' boat for open lake research, and a 16' boat for nearshore studies. Research currently addresses the coupling of the benthic and pelagic food webs as measured by using persistent organic chemicals and stable isotopes.
Much of this information is utilized to develop exposure models. For instance, we are in the process of developing both benthic and pelagic system models, that will eventually be integrated to a form a comprehensive ecosystem model of both energy/carbon and contaminant dynamics.
Laboratory research utilizes both in vitro and in vivo studies. The former is based on human, fish and rat cell lines for the study of cyto and gentotoxicity. The latter is primarily studies of chemical uptake and effects in fish and benthic invertebrates. Research is often performed in collaboration with other universities or government agencies, thus students get to work within a broad research environment. Although current studies emphasize PCBs and PAHs, future research will consider modern pesticides and effects on amphibean populations.
