Academic Degrees:
- Ph.D. Oregon State University, 1989
- B.S. Northeast Louisiana University, 1984
Specialization:
- His research focuses on understanding the biochemical factors that influence susceptibility to environmental and natural chemicals. Four specific projects involve the use of bioassays in the identification of environmental estrogens and other endocrine disrupting compounds in reclaimed water, wastewater and sediments; mechanistic investigations of the effects of salinity on pesticide and selenium toxicity in fish; the role of biotransformation as a mechanism of tolerance to natural and man-made toxic agents; and applied aquaculture research.
