George A. Bray


I am the Principal Investigator for 3 NIH-funded clinical trials (Diabetes Prevention Program Outcomes Study; Look AHEAD; Vitamin D and Type 2 Diabetes). Central to my work is why do we get fat? Is it nature, nurture or both? This questions has been addressed in studies of human beings and in animals that eat high fat diets or are born to be fat.
