Education

Service

I am active in several Nematology Organizations

Courses Taught

Plant Nematology (PLPA 6303)

Research Emphasis

Nematode Taxonomy using both Morphology and Molecular methods, Determining Reproduction of the Reniform nematode on new Soybean Lines and Cultivars, Rotation of Soybean Cyst Resistant Reaction to Control SCN.

Program Area

My interests are in basic and applied research in plant parasitic nematodes. My applied interests include screening for resistance to the reniform nematode (Rotylenchulus reniformis) in soybean (Glycines max) cultivars and breeding lines and the investigation of possible sources of reniform nematode resistance in upland cotton (Gossypium hirsutum). I have also worked extensively with the soybean cyst nematode rotations (Heterodera glycines).

My basic research is on the taxonomy of plant parasitic nematodes, with recent emphasis on the virus vectoring Longidoridae of the genera Xiphinema and Longidorus and presently on the family Hoplolaimidae. I use a combination of morphometric analyses, statistical comparisons, and biotechniques such as RFLP's and DNA sequencing.
