I am interested in factors that structure wetland and coastal land-margin ecosystems. My research focuses on the roles that nitrogen and phosphorus play in organizing biological communities at the base of Great Lakes coastal food webs. I use a variety of field and laboratory techniques to measure nutrient bioavailability including, bioassays, in situ nutrient amendments, and physiological indicators of nutrient limitation.

My recent work characterizes the biogeochemical transformations and measures shifts in planktonic communities along the gradient formed as the water of the St. Louis River, rich in dissolved organic matter, enter the clear water of Lake Superior. In addition to measuring algal communities and nutrient transformations, I am also beginning to investigate the interactions between CDOM and nutrient biogeochemistry along this river-to-lake gradient and developing an understanding of how these ecosystem processes may be affected by changing climate and land use patterns.
