In his 35+ year career, he has defined the relaxation response and continues to lead teaching and research into its efficacy in counteracting the harmful effects of stress. The recipient of numerous national and international awards, Dr. Benson lectures widely about mind/body medicine and the BHI's work. His expertise is frequently sought by national and international news media, and he appears in scores of newspapers, magazines, and television programs each year. Dr. Benson's research extends from the laboratory to the clinic to Asian field expeditions. His work serves as a bridge between medicine and religion, East and West, mind and body, and belief and science.
