David Fields, PhD

David Fields, PhD

Dr. Fields is an Associate Professor and the CMRI Chickasaw Nation Endowed Chair in Pediatric Diabetes.  He completed his PhD in Exercise Physiology from Auburn University while receiving pre-doctoral training at the University of Alabama at Birmingham. Upon graduating, he went on for post-doctoral training in physiology and nutrition at Washington University in St. Louis. 

The overarching focus of his research program is to understand how perinatal body composition affects future health with ≈450 mother/infant dyads currently enrolled in his research programs (i.e.
Baby Peas) with greater than 60% of subjects having multiple year follow-up visits. Specifically, the emphasis is to understand the role of modifiable gravid maternal factors (e.g. diet, physical activity, diabetes, obesity and mode of feeding) on the development of their offspring’s fat and lean mass in the first month of life and the subsequent influence on future disease risk in childhood, adolescence and adulthood. His current NIH study (“Maternal Obesity, Breast Milk Composition, and Infant Growth” $3.6 million; in collaboration with Dr. Ellen Demerath at the University of Minnesota) characterizes human breast milk in a diverse group of mothers with a focus in better understanding how it impacts early body composition.

Kevin Short, PhD

Kevin Short, PhD 

Dr. Short is an Associate Professor and the CMRI Choctaw Nation Endowed Chair in Pediatric Endocrinology.   He earned graduate degrees in exercise physiology (MS, Purdue University) and human bioenergetics (PhD, Ball State University) and completed post-doctoral training in endocrinology and metabolism (Mayo Clinic).  Since 2006 when he joined OUHSC, his research has examined the impact of exercise on insulin sensitivity and vascular health.  The goal is to identify the most effective lifestyle approaches to prevent or reverse the cardiometabolic risk in children and young adults, thereby limiting a potential lifetime of pathology and medical burden.

Ann Louise Olson, PhD

Dr. Olson is the Edith Kinney Gaylord Foundation Presidential Professor in the Department of Biochemistry and Molecular Biology.  She completed her PhD in Biochemistry & Molecular Biology from the University of Iowa in 1986.  Her research interests include the intracellular signals that underlie substrate utilization between the fed and fasted state and how this process breaks down during insulin resistance.
