MD, Professor of Anesthesiology and Psychology. Currently a full time clinical anesthesiologist and Director of the Center for Consciousness Studies at the University of Arizona in Tucson.  Hameroff became interested in intelligent behavior of microtubules, protein lattices which organize activities within living cells, with colleagues developed theories of microtubules as self-organizing molecular computers. In the 1990s, Hameroff teamed with Sir Roger Penrose on the controversial Penrose-Hameroff “Orch OR” model of consciousness based on quantum computing in brain neuronal microtubules, a notion bolstered by recent evidence. In Orch OR, Penrose physics connects brain microtubules to the most basic level of the universe – fundamental spacetime geometry at the Planck scale. The Penrose-Hameroff ‘Orch OR’ model listed as one of six theories of consciousness, World Book of Science 2000 Penrose-Hameroff ‘Orch OR’ model featured in ‘The Scientist’: “Consciousness Studies – an Emerging Discipline?” Related to consciousness research Dr. Hameroff has appeared in numerous shows including two BBC TV shows, a PBS TV segment, a Discovery Channel and several documentary films as well as numerous radio interviews and popular magazine articles (Discover, Scientific American etc.) published 6 books and over 100 research articles.  Hameroff’s writings include: Consciousness: Integrating Eastern and Western Perspectives, Toward a Science of Consciousness The Tucson Discussions and Debates 1, II, III; From Nanobiology to Nanotechnology; Ultimate Computing: Biomolecular Consciousness and Nano Technology; Consciousness in the Universe: An Updated Review of the ‘Orch OR’ Theory.
