My research interests are in applied and basic aquatic ecology with an emphasis on trophic relations, littoral zones, and invasive species. I have a wide range of research interests in fisheries ecology and believe a mix of descriptive and manipulative research is essential. Much of my work is interdisciplinary and has involved collaboration with other researchers.

I am interested in basic and applied aspects of herbivory on freshwater macrophytes by invertebrates. This work includes applied research on potential biological control agents of nuisance weeds such as Eurasian watermilfoil and more basic research on the role of deterrents and attractants in the use of macrophytes by aquatic invertebrates. More recently we have been examining the ecology of invasive aquatic plants such as Eurasian watermilfoil and curlyleaf pondweed. This includes work on effects of large scale treatments to control invasive plants, models to predict invasion and the ecology of propagules such as seeds and turions.

We are particularly interested in approaches to enhance native macrophytes after carp and invasive plant control. Our most recent work is investigating the distribution of hybrid watermilfoil in Minnesota, factors that favor hybrids and identifying hybrid genotypes that may be more invasive or resistant to management. 

I still maintain an interest in stream ecology, but currently have no active projects.
