Christopher received a BA in English and American literature in 1984 and an MA and Ph.D. in psychology from Saybrook University, in San Francisco, CA twenty years later. He spent the intervening decades traveling around the world, living in unexpected places working at very odd jobs (e.g., gutting salmon in Alaska, teaching English to prostitutes in Bangkok and self-defense to land-reform activists in Mexico, managing commercial real-estate in New York’s Diamond District, helping Spanish physicians publish their research). Somewhere along the way, he decided to pursue doctoral studies in psychology. Drawing upon his multi-cultural experience, Christopher’s research focused on trying to distinguish the human from the cultural. His doctoral dissertation analyzes the prehistoric roots of human sexuality, and was guided by the world-renowned

psychologist, Stanley Krippner.Based in Barcelona since the mid-1990s, Christopher has lectured at the University of Barcelona Medical School and consulted at various local hospitals. He speaks about human sexuality to audiences around the world (in both English and Spanish). His work has appeared in major newspapers and magazines in many languages, scholarly journals, and a text book used in medical schools and teaching hospitals throughout Spain and Latin America.Christopher contributes to both Psychology Today and Huffington Post.
