A monthly virtual encounter to reckon whence and whither humanity. Pim van Lommel, M.D., born in 1943, graduated in 1971 at the University of Utrecht, and finished his specialization in cardiology in 1976. He worked from 1977-2003 as a cardiologist in Hospital Rijnstate, a 800-bed Teaching Hospital in Arnhem, the Netherlands, and is now doing full-time research on the mind-brain relation. He published several articles on cardiology, but since he started his research on near-death experiences (NDE) in survivors of cardiac arrest in 1986 he is the author of over 20 articles (most of them in Dutch), one book and many chapters about NDE. He was co-founder of the Dutch IANDS in 1988.
