| Biography: | Dr. John D. Madsen is Associate Extension/Research Professor in the Geosystems Research Institute and the Department of Plant and Soil Sciences, Mississippi State University. Previously, he was an Assistant Professor of Biology at the Minnesota State University, Mankato from 2000 to 2003; and a Research Biologist in the Environmental Laboratory, U.S. Army Engineer Research and Development Center, Vicksburg, MS from 1991 to 2000.
Dr. Madsen has a Bachelor of Science (1980) degree from Wheaton College, Wheaton, IL, and Master of Science (1982) and Doctor of Philosophy (1986) degrees in Botany from the University of Wisconsin-Madison.
He was editor of the Journal of Aquatic Plant Management from 1997 to 2002. He is currently an Associate Editor for the new WSSA journal, Invasive Plant Science and Management. Dr. Madsen is currently the President of the MidSouth Aquatic Plant Management Society (2008-2009), a board member of the Council for Agricultural Science and Technology (2008-2011) representing the Aquatic Plant Management Society, and chairs the Federal and Noxious Weed Committee (E4) for the Weed Science Society of America.

| Research Interest: | Dr. Madsen has been studying the biology, ecology, and management of aquatic plants since 1980, and has authored over 70 peer-reviewed articles on this topic. His primary research has been on the ecology and life history of invasive aquatic plants such as Eurasian watermilfoil, curlyleaf pondweed, waterchestnut, and waterhyacinth. Research on management of these species has included optimizing biological, chemical, mechanical and physical control techniques by targetting the timing of control to life history characteristics of the plants. He has also worked on the restoration of native aquatic plant communities.
Dr. Madsen has also worked on other invasive species issues as part of a multi-disciplinary team. These projects have included invasive terrestrial plants and invasive insects.
