Dr. Sapolsky is a MacArthur “Genius” Fellow, a professor of biology, neurology, and neurosurgery at Stanford University, and a research associate at the National Museum of Kenya. His 2008 National Geographic special on stress, and his online lectures about human behavioral biology, have been watched tens of millions of times. The humor and humanity he brings to sometimes-sobering subject matter make Dr. Sapolsky a fascinating speaker. He lectures widely on topics as diverse as stress and stress-related diseases, biology and the free will debate, the biology of our individuality, the biology of religious belief, depression, memory, schizophrenia, and Alzheimer’s disease.
