Biographical Sketches of Invited Speakers and Panelists
Bernd Blossey - Associate Professor, Cornell University, Department of Natural Resources and Director of the Ecology and Management of Invasive Plants Program. A native of northern Germany, Bernd attended Kiel University with an initial interest in marine biology. He became fascinated by insects, then by birds, plants and mammals. He realized that he was an ecologist with wide ranging interests. Following a summer internship at the Commonwealth Institute of Biological Control in Switzerland in the mid 1980's, he completed a Masters degree and a PhD, studying insect communities on purple loosestrife. This study was motivated by the interest of potentially using insects from the native range of purple loosestrife as biological control agents. In 1992, Bernd moved to Cornell University, initially as a post-doc and Research Associate. He and his team study impacts of invasive plants on a wide range of native organisms. Bernd also continues to develop and implement biological weed control programs. Among his target plants are purple loosestrife, garlic mustard, Phragmites, Japanese knotweed and water chestnut.
Cynthia Boettner - Biologist with the Silvio O. Conte National Fish and Wildlife Refuge of the U.S. Fish and Wildlife Service. She coordinates the New England Invasive Plant Group and the Massachusetts Invasive Plant Advisory Group, working with numerous partners to address invasive plant issues.

Biographical Sketches of Invited Speakers and Panelists, continued
Robin Harrington -Associate Professor with the Department of Natural Resources Conservation at the University of Massachusetts at Amherst. Much of her research over the past 20 years has focused on the ecology of invasive plant species in wetland and forest habitats. Recently she has focused on the response of Oriental bittersweet (Celastrus orbiculatus) and Japanese barberry (Berberis thunbergii) to resource availability, and the effect of Phragmites (Phragmites australis) on native swale vegetation and the subsequent response of the native plant community to Phragmites removal.
Bob Heffernan - Executive Director, Connecticut Green Industries Council. The Connecticut Green Industries Council includes the Connecticut Florists Association, Connecticut Greenhouse Growers
Association, and Connecticut Nursery & Landscape Association. Bob has been instrumental in
delivering the green industry views about invasive plants, and in drawing up invasive legislation for the CT state legislature.
