My primary research interests are in the area of nematode management and ecology. The program addreses basic and applied aspects of nematode management in cotton and soybean. On-farm research is conducted in the eastern part of North Carolina and serves as demonstration sites for extension. Host plant resistance, cover crops, rotation and other cultural practices are evaluated in field scale experiments. Cooperative studies are conducted with faculty in the crop and soil sciences departments.

Extension & Outreach
My current appointment is 60% Extension for most field crops grown in North Carolina, including soybean, corn, cotton, and small grains. Diagnosis of diseases of these crops is a large but enjoyable portion of my work. The format is principally a “research and extension on wheels program” conducted across the eastern portion of the State of North Carolina.
