Research Overview

Dr. Shankar is an Investigator at the Arkansas Children’s Nutrition Center and an Associate Professor in the Department of Pediatrics, Division of Gastroenterology, Hepatology and Nutrition at UAMS. Research in his laboratory is focused on two central themes. The first area of investigation is to understand the developmental origins of childhood and adult obesity, specifically the long-term consequences of maternal obesity on the offspring. The research projects involve a wide range of experimental approaches including animal models, cell culture, molecular biology and genomics. The overall objectives of these studies are aimed at gaining a better mechanistic understanding of the physiological basis of fetal programming and through translational studies, provide novel opportunities for effective intervention. Studies examining facets of adipocyte biology and development are also in progress. The second area of investigation relates to health consequences of chronic alcohol consumption, specifically metabolic and endocrine derangements in liver, bone, and adipose tissues.

Dr. Shankar received his PhD in Toxicology from the University of Louisiana at Monroe and is a Diplomate of the American Board of Toxicology.
