Robert Waldinger

Robert Waldinger is a world-renowned psychiatrist and Professor at Harvard Medical School, celebrated for his pioneering work in the fields of mental health and human wellbeing. As Director of the Harvard Study of Adult Development—the longest-running scientific study of happiness—Robert has become one of the most respected voices on what it means to live a fulfilling life. With decades of experience researching the human mind and behaviour, he blends scientific expertise with lived insight, offering audiences transformative guidance on mental wellness, emotional intelligence, and meaningful relationships.

Since taking the helm of the Harvard Study in 2005, Robert has led the research into its second generation, studying the children of the original 724 male participants. Under his stewardship, the project has evolved into a cornerstone of psychological research, providing critical data on how lifelong happiness is shaped by relationships, not material success. A summa cum laude graduate of Harvard College, Robert’s academic credentials are matched by his deep commitment to applying research in practical, accessible ways—particularly through his teaching, public speaking, and writing.

One of Robert’s most powerful contributions to the conversation around wellbeing came in 2015, when he delivered the TED Talk “What Makes a Good Life? Lessons from the Longest Study on Happiness”. The talk, now with over 20 million views, captivated global audiences with its compelling message: that strong, supportive relationships are the most significant predictor of long-term happiness and health. Robert’s ability to distil complex psychological insights into relatable life lessons makes him a sought-after speaker for corporate events, where his expertise helps organisations support employee wellbeing and navigate change with empathy and foresight.

In addition to his academic work, Robert is a Zen priest and the Executive Director of the Lifespan Research Foundation, further enhancing his holistic approach to mental wellness. His dual perspectives—from science and spirituality—allow him to speak with a rare depth and authenticity. Whether addressing the power of connection or the inevitability of change, Robert’s insights inspire real, lasting impact.
