Education:
Ph.D., Ecology, Pennsylvania State University, 1991
M.S., Ecology, Pennsylvania State University, 1986
B.S., Wildlife Biology, University of Tennessee (Martin), 1983
Research Interests:
Research interests range from investigating the ecology of non-game stream fish, especially movement and mortality responses to physical and chemical conditions, to determining the effects of zebra mussels on a large reservoir (Lake Dardanelle). These studies have led to investigations of the effects of seasonal, stream-drying on non-game and gamefish, particularly smallmouth bass. Undergraduate students gain experience on these projects and regularly present papers at state and regional meetings.
