研究领域

I am interested in studying the sublethal effects of contaminants in aquatic ecosystems. Currently, I am focusing on two contaminants of interest in Iowa: phosphorus and atrazine. My students and I, along with Dr. Ed Brown and Dr. Mohammad Iqbal, are studying phosphorus in local lakes, as well as potential methods to reduce phosphorus bioavailability. We have also investigated the production of microcystin-LR by cyanobacteria in local lakes. We are also examining the effects of atrazine, an endocrine disruptor, on human cell proliferation in collaboration with Dr. Kavita Dhanwada and on fish reproductive physiology in collaboration with Dr. Pete Berendzen.
