Dr. Robert Waldinger is Clinical Professor of Psychiatry at Harvard Medical School, and Director of the Harvard Study of Adult Development, the longest longitudinal studies of adult life ever done. His research focuses on what predicts healthy adult development. For 80 years, the Study has followed 2 groups of men recruited as teenagers from Harvard College and from Boston inner city neighborhoods. Funded by the National Institute on Aging, he is now studying more than 1300 of the baby-boomer children of these men to track the influence of childhood experiences on midlife health. His 2015 TED talk about the Study has been viewed by over 20 million people and is one of the most popular TED talks of all time.
