Major Professional Activities since joining UGA in 1974


2004-2007. Development of Spring Valley organic farm as a research, educational, and outreach center.

2000- 2004. Co- PI on a multi-million grant from USDA to establish a “Center for Sub-Tropical Agroforestry. Research sites include several stations in Florida, and the “Spring Valley Farm” (see below) in Georgia.

1993-present. In 1993, I purchased a 100 acre farm (Spring Valley Farm) near Athens for use as a facility for research and teaching in agroecology and organic agriculture. Over the years, the intensity of use by graduate and undergraduate students has increased. By 2006, over 2000 undergraduates visited the farm for field exercises (ECOL 1000, 2 semesters/yr, ECOL 3500 3 semesters/yr). Undergraduates from Gainesville State College and Gwinnet College also visit the farm every year. I have used the farm for graduate courses in agroecology (ECOL 8440), and every May since 2004, I have given a Maymester course in organic agriculture (ECOL 3700). In 2006, an intensive graduate course in landscape design was given at the farm. I currently teach part of the curriculum for the “Certificate in Organic Agriculture” Program (AESC 3126) at the farm. Two Ph.D. students and one M.S. student have received their degrees from research on the farm. Two other Ph.D. students are currently using the farm for their Ph.D. research. The farm also hosts University groups from the State Botanical Garden, International Education, Environmental Ethics, as well as outside groups interested in sustainable agriculture.
