Alexandre Roulin is 55 and a full professor of biology at the University of Lausanne, Switzerland. He took an atypical career path by doing an apprenticeship of civil engineering. He then did a night school to get his “maturity degree” before going at the university. Always interested in birds since the age of 7, his main scientific interests are the adaptive function of melanin-based coloration and negotiation processes taking place in animal societies using the barn owl as a model organism. Since 2009, he actively participates in the project of promoting cooperation between the Israeli, Palestinian and Jordanian communities using nature conservation as a tool. His ambition is to reconcile human with nature and to use this inter-disciplinary approach to promote peace and respect to our environment.
