Stuart Hameroff, MD, is an anesthesiologist and professor at the University of Arizona known for his promotion of the scientific study of consciousness, and his speculative theories of the mechanisms of consciousness. His early research suggested to him that part of the solution to the problem of understanding consciousness may lie in understanding the operations of microtubules in brain cells, operations at the molecular and supramolecular level.
