Dr. Austin Graybeal

Dr. Austin Graybeal is an Assistant Professor at the University of Southern Mississippi School of Kinesiology and Nutrition and is a certified strength and conditioning specialist (CSCS). His research explores the utility of machine learning in body composition estimation from remote settings using common devices not subjected to geographical or monetary restrictions. Further, Dr. Graybeal's research focuses on a variety of dietary interventions with the primary goal of obtaining a healthy body composition through nutrition and physical activity. His research is driven by his desire to reduce the global obesity burden and offer accessible and affordable services to underserved populations who suffer from obesity to a greater degree. Dr. Graybeal has managed projects that have produced the first comprehensive characterizations of fat-free tissue in individuals with abnormal body compositions and has validated several body composition devices for individuals outside of "normal" body compositions. He has also overseen several projects focused on acute and chronic dietary interventions, specifically, high-fat or low-carbohydrate interventions and their influence on metabolism, appetite, and cardiometabolic health markers. He is currently managing a project funded by Mississippi INBRE, which examines how machine learning from high-quality smartphone cameras can accurately estimate body composition through three-dimensional optical scanning for use in remote healthcare settings.
