Stuart Hameroff’s research pursued microtubule information processing and anesthetic action. In the mid-1990s he teamed with eminent British physicist and Nobel Laureate Sir Roger Penrose to develop a controversial quantum theory of consciousness (‘orchestrated objective reduction’, ‘Orch OR’) based on microtubule quantum computing. Harshly criticized initially, Orch OR is now supported by experimental results including anesthetic action. In 2017, with Sir Roger Penrose, James Tagg, Ivette Fuentes and Erik Viierre, Hameroff co-founded the Penrose Institute, intended to support research based on the various works of Sir Roger (cosmology, quantum mechanics, general relativity, black holes, geometry and consciousness).
