Walter Willett

WALTER WILLETT, MD, DrPH is professor of epidemiology and nutrition at Harvard T.H. Chan School of Public Health and professor of medicine at Harvard Medical School. Walter studied food science at Michigan State University and graduated from the University of Michigan Medical School before obtaining a doctorate in public health from Harvard School of Public Health. He has focused much of his work over the last 35 years on the development of methods, using both questionnaire and biochemical approaches, to study the effects of diet on the occurrence of major diseases. He has applied these methods starting in 1980 in the Nurses’ Health Studies I and II and the Health Professionals Follow-up Study. Together, these cohorts that include nearly 300,000 men and women with repeated dietary assessments are providing the most detailed information on the long-term health consequences of food choices. Walter has published over 1,700 articles, primarily on lifestyle risk factors for heart disease and cancer. In addition to the textbook, Nutritional Epidemiology (Oxford University Press), he has authored four books for the general public: Eat, Drink and Be Healthy: The Harvard Medical School Guide to Healthy Eating, which has appeared on most major bestseller lists; Eat, Drink, and Weigh Less, co-authored with Mollie Katzen; The Fertility Diet, co-authored with Jorge Chavarro and Pat Skerrett; and Thinfluence, co-authored with Malissa Wood and Dan Childs. Walter is a member of the National Academy of Medicine and the recipient of many national and international awards for his research. He is the most cited person in all areas of science.
