Prof. Reuven Yosef was born in Pune, India in 1957 and immigrated to Israel in 1974. He earned a Ph.D. in Conservation Biology, Wildlife Management, Zoology and Behavioral Ecology in 1992 at The Ohio State University, and a post-doc from Cornell & Archbold Biological Station. Between 1992-1994, Reuven was a scientific advisor to the NASA Space Shuttle Program at the Kennedy Space Center, Cape Canaveral, Florida. He became Director of the International Birding and Research Center in 1993, and his dedication to his work within Israel and internationally has been recognized by the following awards: 2008, "Israel;'s Visionary." President of Israel and Council for Green Israel; 2003, Special Distinction. Ford Motor Company Conservation & Environment Award; 2000, Associate Laureate. Rolex Awards for Enterprise - Environment; 2000, Runner-up. Conde Nast Traveler Environmental Award; 1998, Environment Man-of-the-Year. Swarovski Optics; 1995, Distinguished Eco-tourist Operator. Ministry of Tourism, Eilat, Israel. In addition to his work at Eilat, he has been involved in The Global Shrike Monitoring Program, the Scientific Committee for the Ecology & conservation of steppe-land birds, Catalonia, Spain; Scientific Committee, 1st & 2nd International Eurasian Ornithology Congress, Antalya, Turkey; Organizing Committee of 1st-4th International Shrike Symposium; Imperial Eagle Working Group, Birdlife International, Hungary; Advisor to Eleonora;s Falcon Study Group, EULIFE, Greece; was vice-president of the South East European Migration Network (SEEN); was International Director of the Raptor Research Foundation.
In addition, he also lectures at Ben Gurion University of the Negev and at the Arava Institute. He was part of a team in Mongolia this summer working against the accidental electrocution of Birds of Prey. He continues his conservation work in Israel, India and Mongolia.
