Scientifically, Dr. Buchanan conducts research into the etiology, pathogenesis, genetics and prevention of gestational and type 2 diabetes with a focus on diabetes in Hispanic Americans. Buchanan and colleagues have conducted longitudinal studies of high risk individuals to define patterns of change in insulin resistance and insulin secretion that lead to type 2 diabetes. Based on their findings, they then conducted the first successful type 2 diabetes prevention study in the United States. The biological information gained from that study points to a specific pancreatic beta cell defect that is heritable. The group is conducting a large family based study designed to identify the genetic basis for the beta cell defect. Buchanan’s work has garnered him many awards, including the Norbert Freinkel Award and Distinguished Clinical Science Award from the American Diabetes Association and the Mayo Soley Award from the Western Society for Clinical Investigation.
