Dr Harran holds a PhD in science and was assistant professor and researcher in physics at the University of Pau, France. For the past 14 years, he has studied mysterious phenomena that science has yet to explain (crop circles, then UFOS), using a rational approach. He has developed an interpretation different from the classic extraterrestrial hypotheses. Sources of knowledge left behind by science have served as support for his arguments. He shares his findings through his publications (eight books published so far) and via his website: https://listentotheearth.net. This site receives an average of 5,000 visits per month. Now retired from his university occupation, Dr. Harran is fully devoted to his research. He regularly gives lectures, and in addition to his website he maintains an interactive blog on these subjects.
