Ecology of Parasitic Nematodes (NEM 203)
Concepts and Systems of Plant Protection and Pest Management (IPM 201)
My research interests are in integrated pest management and ecology of nematodes in agroecosystems. The research in my laboratory is focused on plant-parasitic nematode management, especially with respect to alternative management strategies as supplements to rotations and nematicide applications for use in sustainable agricultural production systems. We also conduct research on the ecology of aging in the nematode Caenorhabditis elegans. This research involves a demographic approach to aging, including investigating the natural ecology of the nematode, and how its life history features are reflective of its ecology.
