Jon Kabat-Zinn is an American professor emeritus of medicine and the creator of the Stress Reduction Clinic and the Center for Mindfulness in Medicine, Health Care, and Society at the University of Massachusetts Medical School. Kabat-Zinn was a student of Zen Buddhist teachers such as Philip Kapleau, Thich Nhat Hanh, and Seung Sahn, and a founding member of the Cambridge Zen Center. His practice of hatha yoga, Vipassanā, and appreciation of the teachings of Soto Zen and Advaita Vedanta led him to integrate their teachings with scientific findings. He teaches mindfulness, which he says can help people cope with stress, anxiety, pain, and illness. The stress reduction program created by Kabat-Zinn, mindfulness-based stress reduction (MBSR), is offered by medical centers, hospitals, and health maintenance organizations, and is described in his book Full Catastrophe Living.

Kabat-Zinn received his Ph.D. in molecular biology from MIT in 1971 in the laboratory of Nobel Laureate, Salvador Luria. He is the author of numerous scientific papers on the clinical applications of mindfulness in medicine and health care, and of a number of books for the lay public.
