Research Specialty:

Conducts research on the systematics and morphology of plant-parasitic nematodes. Identifies nematodes from federal, state, and foreign agencies and scientists for research, control and regulatory purposes. Curates and expands the USDA Nematode Collection. Develops data on nematode hosts, occurrence and distribution.

Current Research Interests:

Plant-parasitic nematodes of order Tylenchida and some forms of Dorylaimida group; morphometric data and SEMobservations for the description of economically important cyst, root-knot, lesion, needle, seed gall and other nematodes; develop key and compendium to species of the stunt nematodes (Merlinius spp.) and other plant-parasitic nematode genera; provide nematode identifications and taxonomic expertise urgently required by ARS scientists, other federal and state researchers, and regulatory agencies for research, regulatory and control purposes; develop new methods for identifying nematodes quickly and accurately; curate and expand the USDA Nematode Collection and use the resources of the Collection to better understand nematode systematics.
