Randall S. Hewes Randall S. Hewes Professor of Biology & Dean of the Graduate CollegeRobertson Hall 213 Office phone: 405-325-3811; Lab phone: 405-325-2540 Ph.D., Zoology - University of Washington, 1993


The research in my lab is focused on the plasticity of neuroendocrine signaling, with special attention to neuropeptide and peptide hormone (peptidergic) systems and their roles in animal behavior.
