Michael Paul Masters, is an author and professor of biological anthropology at Montana Tech in Butte, Montana. He received a Ph.D. in Anthropology from The Ohio State University in 2009, where he specialized in hominin evolutionary anatomy, archaeology, and biomedicine. In his recent book The Extratempestrial Model, Dr. Masters uses an abductive approach to logically infer the best explanation for extra-terrestrial activity and encounters. He examines well-documented abductee experiences in the context of a time travel model, and considers other theories put forth to elucidate this complex and mysterious phenomenon.
