| Research Goals: Nematodes are omnipresent. They occupy almost every conceivable niche that is capable of supporting life, and are purported to be the most numerous animals in the world. Plant parasitic species that attack cultivated crops in the USA are responsible for damage exceeding $9,000,000,000 annually. I am interested in the interactions of nematodes with their host plants at the organismic, cellular, and molecular level. Currently my research is focused on the nematode surface coat, the outermost boundary between the nematode and its environment. Nematode survival is dependent upon exchange of materials across this boundary and through the body wall. The surface coat may also mediate host-parasite recognition systems, and is involved in the attachment of bacteria and fungi that parasitize nematodes. Immunological, biochemical, and ultrastructural methods are being utilized to characterize the surface coat and determine its origin. On the more practical side, my research interests include nematode population management by biological, cultural, and chemical methods. Experimental approaches include laboratory, greenhouse, and field experiments with a broad spectrum of biological and chemical agents, as well as cultural methods, to reduce nematode populations and sustain crop yields. |
