I am currently director of the UW Aquatic Sciences Center, which houses the UW Sea Grant Institute and the UW Water Resources Institute. Both programs are federal-state partnerships which support research, outreach and education in support of sustainable uses of our state's natural resources.
My recent research has centered on cycling of mercury in the aquatic environment. I plan to continue to conduct research on low-level trace metal cycling, especially with regard to factors affecting bioaccumulation in plankton and fish. I plan to utilize stable isotopic techniques to study transport and transformations of trace metals in the environment.
My past research has also focused on natural organic compounds in lakes and rivers. I am particularly interested in developing research projects that build on our experiences studying natural aquatic pigments (chlorophyll, carotenoids and other accessory pigments) and gaining better insight into processes responsible for production of key algal toxins in Wisconsin waters.
