Dr. Gerich received his B.A. from Cornell University and his M.D. from Georgetown University. Dr. Gerich has been productive as both a clinical investigator (over 500 publications) and as a teacher (nearly 50 clinical research fellows) for nearly 35 years. His research examines hormone-substrate control of glucose homeostasis and of hypoglycemia counter regulation by evaluating the role of the kidney. Dr Gerich has also served as Program Director of the NIH funded Clinical Research Center (CRC). He is also an active faculty member of the University's Clinical and Translational Science Institute (CTSI).
