My research focuses on several ecological and environmental issues. I study ecology and management strategies of invasive animals and plants including zebra mussels, European frogbit, and Eurasian watermilfoil. I also investigate impacts of human activities such as urbanization and land use on water quality, specifically water pollution associated with excessive nitrogen and phosphorus, chemical waste, and heavy metals. Additionally, I am interested in biodiversity and distribution of aquatic plants and interspecific interactions in the aquatic plant communities. Currently I am an Associate Editor of Journal of Plant Ecology and Journal of Aquatic Plant Management.
