Research:
Basic signal transduction pathways. My laboratory studies basic signal transduction pathways. We are particularly interested in mapping pathways that regulate proliferation of cells of ion transport. We use state of the art molecular and cellular biology methods, physiological methods, and novel biophysical instrumentation. In one example of this approach, we have been characterizing urea transporters in stingrays. These studies involved determining urea clearances in living anesthetized animals, as well as efforts to clone the cDNA's for a family of urea transporters from these animals.
