Dr. Bennett is also President of the Society of Behavioral Medicine. Dr. Bennett’s research program designs, tests, and disseminates digital obesity treatments. He is especially interested in integrating digital health treatments into the primary care setting. Dr. Bennett developed the interactive obesity treatment approach (iOTA); his recent work demonstrates the effectiveness of coach-led, digital obesity treatments. He has authored more than 125 scientific papers and his research program has been continuously supported by the National Institutes of Health. Dr. Bennett’s research has been featured in the New York Times, NPR, Time, CBS, ABC, NBC, Fox News, and many other media outlets. Dr. Bennett is a member of the American Psychological Association’s obesity treatment guidelines panel and works with committees at Girl Trek, the Institute of Medicine, American Heart Association, and American Council on Exercise to reduce Americans’ high rates of physical inactivity and obesity. He also co-founded two digital health startups: Crimson Health Solutions (acquired by Health Dialog in 2007) and Scale Down. Prior to joining Duke in 2009, Dr. Bennett served on the faculties of the Harvard School of Public Health and the Dana-Farber Cancer Institute.
