Program Statement |
I strive to improve agronomic production systems via the discovery, integration, and implementation of better crop and soil management practices that benefit agriculture and our society at large. |
Education: |
|
Ph.D. in Agronomy, Texas A&M University, 1993. M.S. in Crop Science, North Carolina State University, 1987. B.S. in Agronomy, North Carolina State University, 1985.
|
Professional Background: |
|
2002-2009: Associate Professor and Extension Agronomist, Virginia Polytechnic Institute & State University. 1997-2002: Assistant Professor and Extension Soybean Specialist, Virginia Polytechnic Institute & State University. 1993-1996: Assistant Professor and Integrated Weed Management Specialist, University of Nebraska. 1987-1993: Research Associate, Texas Agricultural Experiment Station. 1985-1987: Graduate Research Assistant, North Carolina State University. |
Research & Educational Interests and Repsonsibilities |
My research and educational interests include cropping systems, precision agriculture, pest management, Palmer amaranth control, yield enhancement with strobilurin fungicides, and optimal soybean seeding rates. I conduct the official soybean variety test in five regions throughout the Commonwealth and serve as educational adviser to the Virginia Soybean Association and Virginia Soybean Board. |
