Bio: Dr. Gallandt received his B.S. (1986) from Michigan State and M.S. (1988) from Montana State University.  He received his Ph.D. from the University of Wisconson in 1994.  He joined the faculty in 2000 and is an Associate Professor of Weed Ecology.

Teaching:  PSE105 Principles of Sustainable Agriculture; PSE203 Weed Biology and Identification; PSE403 Weed Ecology and Management

Current Research:  My research program focuses on the dynamics and management of annual weeds in organic farming systems.  We continue to study weed seed predators, with current projects investigating the effects of agroecosystem landscape on predators and predation, and hyperpredation and behavior of Harpalus rufipes.  Fall weed management to maximize seed losses is another focus, including recent work on no-till cover cropping to encourage seed predation, preemption of seed rain, and fall flaming effects on weed seed viability.  We are also working on a large interdisciplinary project in which we have characterized Mental Models for weeds and weed management by both experts and organic farmers, aiming to identify important areas of incongruity.
