Biography

Dr. Zigman grew up in New Jersey and performed undergraduate studies at Cornell University. He obtained a dual M.D.-Ph.D. degree from the University of Chicago and remained in Chicago to complete an Internal Medicine residency. Dr. Zigman next moved to Beth Israel Deaconess Medical Center in Boston, where he completed a fellowship in Endocrinology, Diabetes and Metabolism. It was in Boston, while working under the mentorship of Drs. Joel Elmquist and Jeffrey Garber, where Dr. Zigman’s research interests in the hormone ghrelin and the CNS control of eating, body weight, and blood glucose and where his clinical interests in thyroid nodular disease and thyroid cancer first arose.

Dr. Zigman is a Professor of Internal Medicine at UT Southwestern, where he is affiliated with the Division of Hypothalamic Research and the Division of Endocrinology & Metabolism. He holds a secondary appointment in the Department of Psychiatry and also is affiliated with the Integrative Molecular and Biomedical Sciences Graduate Program and the Neuroscience Graduate Program.

Dr. Zigman’s clinic primarily focuses on the treatment of individuals with thyroid nodules and thyroid cancer.

Dr. Zigman’s research is geared toward understanding the neuro-hormonal framework underlying metabolism. In particular, the Zigman lab focuses on how gastrointestinal hormones such as ghrelin interact with the brain, peripheral nervous system, and various peripheral organs to control eating, body weight, blood glucose, responses to exercise, and mood. Conditions studied by the lab include obesity, diabetes, hypoglycemia, cachexia, Prader-Willi Syndrome, and depression.
