Dr. Williams has been a faculty member in the Department of Horticulture at the University of Kentucky since 2001 and is currently the Chair of the department. His research interests are in sustainable agriculture, with a particular focus on evaluating and developing sustainable organic horticulture production systems. Dr. Williams has conducted a range of experiments in organic farming, from optimizing the production of direct-marketed vegetables to developing control options for specific pest problems in cucurbits, peppers, tomatoes and apples. In addition to research, Dr. Williams is committed to student learning and led the development of the UK Sustainable Agriculture undergraduate program. As part of these efforts he established the 30-acre UK Organic Farming Unit, which houses a community supported agriculture (CSA) program and associated student apprenticeship. The Organic Farming Unit is used in a variety of extension and farmer training programs across all topic areas associated with diversified vegetable production.
