    Research Overview

  • The focus of Dr. Ovalle's research over the last 20+ years has been the areas of diabetes and energy metabolism and involves extensive experience in clinical trials concerning the pharmacologic management of diabetes mellitus and its complications, the effects of diet on insulin sensitivity and energy metabolism, and the study of novel therapies for type 1 diabetes. He is also interested in the epidemiology, classification, and pathophysiology of the less well understood sub-types of diabetes mellitus, including Latent Autoimmune Diabetes of the Adult, Monogenic Diabetes, Lipodystrophy Syndromes, and Atypical Diabetes.
