Professional StatementAs a pediatric endocrinologist, I am well trained in the medical management of obesity and type 2 diabetes. Although I have observed vastly different clinical phenotypes of obesity, I am unable as a clinician to effectively treat these patients with the current medical therapies. Thus, I am highly motivated to increase medical knowledge on the pathogenesis of obesity and diabetes and translate it into more clinically effective therapies, specifically for the pediatric population. During my clinical endocrinology fellowship, I was mentored by Drs. Randy Seeley and Darleen Sandoval, experts in the brain’s control of weight and glucose. I used the knowledge from their expertise to investigate the mechanism behind a common clinical correlation: vitamin D deficiency and different components of the metabolic syndrome (including obesity and type 2 diabetes). I chose to defer accepting a faculty position as a pediatric endocrinologist to invest additional time into research training. My research has shown an important effect of the brain in the weight-lowering properties of a commonly used adult diabetic medication, liraglutide. My current research projects stem from my interest in the role of vitamin D signaling in the brain to control weight and glucose. I am clinically involved in the Program for Healthy Bodies Clinic and the Endocrinology Clinic at Texas Children's Hospital.

- Central Vitamin D in Weight and Glucose Regulation
- We are investigating the role of the vitamin D receptor in weight and glucose regulation. This includes the use of genetic mouse models as well as investigations of the interaction of diet with vitamin D receptor action.
