Biography
Dr. Hwang is an endocrinologist and Assistant Professor in the Division of Endocrinology at the Yale School of Medicine. She graduated magna cum laude from Princeton University in 2001 with a major in molecular biology followed by Harvard Medical School in 2006. She completed her residency training in Internal Medicine at the Beth Israel Deaconess Medical Center in Boston, MA and also served as a Chief Medical Resident. Dr. Hwang received her fellowship training in Endocrinology and Metabolism at Massachusetts General Hospital and moved to Yale in 2012 to continue her research training with Dr. Robert Sherwin. Her academic interests are at the intersection of metabolism, neuroscience and imaging. Her research focuses on using advanced brain imaging modalities such as functional MRI and magnetic resonance spectroscopy coupled with classic investigative techniques in metabolism to understand the effects of diabetes and obesity on the brain. Her research has been supported by the National Institutes of Health, the Yale Diabetes Research Center, the Endocrine Fellows Foundation, and the American Diabetes Association. She is the recipient of several awards for her research including the Marilyn Fishman Award for Diabetes Research, the Metabolism Junior Investigator award as well as a Yale Center for Clinical Investigation Junior Faculty Scholars Award.
