Considered one of the foremost experts on the brain, Robert Ornstein was an internationally renowned psychologist and author of more than 20 books on the nature of the human mind and brain and their relationship to thought, health, and individual and social consciousness. Perhaps best known for his pioneering research on the bilateral specialization of the brain, Ornstein continually emphasized the necessity of "conscious evolution" and the potential role of the right hemisphere in expanding our horizons to meet the challenges of the 21st century. He taught at Stanford University, Harvard University and the University of California, San Francisco. His books have sold over six million copies worldwide, have been translated into dozens of languages and used in more than 20,000 university classes. He founded the Institute for the Study of Human Knowledge (ISHK) in 1969 and served as its president until his death in December of 2018.
