Postdoctoral Fellowship in Toxicology – University of Rochester School of Medicine
Field
Aquatic Toxicology, Water Pollution Biology
Interests
In general, my research interests are environmental and comparative toxicology and water pollution biology. Specifically, I am studying the effects of water pollution, such as acid coal mine drainage on macroinvertebrate community structure. I am particularly interested in water mite assemblages and the interactions between water mites and aquatic insects. In addition, I am studying the effects of nitrate and nitrite on the hematology of aquatic insects and the embryology of fish.
