After completing a medical internship at Mt. Zion Hospital in San Francisco, he worked a year with the National Institute of Mental Health, then wrote his first book, The Natural Mind. From 1971-75, as a Fellow of the Institute of Current World Affairs, Dr. Weil traveled widely in North and South America and Africa collecting information on drug use in other cultures, medicinal plants, and alternative methods of treating disease. From 1971-84 he was on the research staff of the Harvard Botanical Museum and conducted investigations of medicinal and psychoactive plants. At present, Dr. Weil is Director of the Program in Integrative Medicine of the College of Medicine, University of Arizona, where he also holds the Lovell-Jones Endowed Chair in Integrative Rheumatology and is Clinical Professor of Medicine and Professor of Public Health. The Program is the leading effort in the world to develop a comprehensive curriculum in integrative medicine. Graduates serve as directors of integrative medicine programs around the United States, and through its Associate Fellowship, the Program is now training doctors and nurse practitioners around the world.
