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.

Much of my work has 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, and the ecology of propagules such as seeds and turions. We are particularly interested in approaches to enhance native macrophytes after carp removal, alum treatments 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. 

Finally, I have an interest in coastal marine ecology and am investigating ways to map seagrass and other coastal lagoon features using sonar and photographs.  I do not anticipate taking on new graduate students but have several undergraduate projects available.
