T.O. Powers' Research

Dr. Powers’ primary interest is in the evolutionary biology of plant parasitic nematodes. Most of the research in his lab focuses on questions of systematics or evolutionary genetics. Since so many nematodes are agricultural pests, developing diagnostic methods is also part of the business. Our lab favors molecular methods, particularly in light of their versatility and the nature of nematodes. One ongoing project is the characterization of all the nematodes in a single location, using a standard set of molecular characters.
