PROFESSIONAL EXPERIENCE 

1995-present Associate Professor, Ohio State University

AREAS OF RESPONSIBILITY IN EXTENSION, RESEARCH, TEACHING

Current research interests are the biology and ecology of seeds of weedy and invasive species as related to mechanisms of spread and persistence and targets for improved weed management strategies. Recent efforts have addressed the impact of vertebrate and invertebrate organisms on seed dispersal, seed predation, and seed survival in giant ragweed (Ambrosia trifida), a major annual weed in grain crops. An additional interest is the development of weed control methods for organic vegetable and grain crop production. Regular teaching responsibilities are HCS 422 (Principles of Weed Science, responsible for lab) and HCS 414 (Crop Science Lab). Additional courses offered on an ad-hoc basis are HCS 694 and 830 (Current Topics in Weed Biology/Ecology).
