UC Davis social psychologist Al Harrison has been studying the psychology of space exploration for 20 years, including the search for life beyond Earth. Author of the 2001 book, "Spacefaring: The Human Dimension," Harrison can talk about life support, habitability, crew selection and training, coping with stress, group dynamics, accidents, off-duty activities, space tourism, space settlements and interstellar travel. He can also discuss the organizational and political contexts that shape human progress in space. His earlier books include "From Antarctica to Outer Space: Life in Isolation and Confinement" (1991) and "After Contact: The Human Response to Extraterrestrial Life" (1997).
