Dr. Stuart Hameroff was born in Buffalo, New York and grew up in Cleveland, Ohio where he worked at Republic Steel and Cleveland Stadium. He earned his undergraduate degree at the University of Pittsburgh, and received his MD at Hahnemann in Philadelphia in 1973. He then moved to Tucson, where in 1975 he became the sixth resident in the Department of Anesthesiology at the University of Arizona. Joining the faculty in 1977, Dr. Hameroff has stayed ever since. Dr. Hameroff's research for 35 years has involved consciousness (how the pinkish gray meat between our ears produces the richness of experiential awareness). Studying anesthetic gas mechanisms, he focused on how quantum effects control protein conformational dynamics. Following an interest which began in medical school in the computational capacity of microtubules inside neurons, Dr. Hameroff teamed up with the eminent British physicist Sir Roger Penrose in the early 90's to develop a highly controversial theory of consciousness called ‘orchestrated objective reduction’ (Orch OR). Dr. Hameroff began the international, interdisciplinary biennial conferences on consciousness (Toward a Science of Consciousness) in 1994, becoming Director of the Center for Consciousness Studies at the University of Arizona. He has published five books and well over 100 research articles, and appeared in the film ‘What the Bleep do We Know?’ and numerous TV documentaries on the problem of consciousness.

Research Interests:
