Education:
M.S. 1991 in Biology University of Wisconsin - La Crosse
B.S. 1988 in Biology University of Wisconsin - La Crosse

Primary Responsibilities/Activities:
My research focuses on the use of molecular tracers, such as fatty acids, to determine foodweb linkages and as indicators of habitat quality;  the quantification of limiting factors that control biogeochemical cycling of nitrogen in small and large rivers; and the affect of anthropogenic nutrient enrichment on the productivity and species assemblages in large rivers.
