He did his national military service in the Israel Defense Forces as the commander of an anti-aircraft battery in the Israeli Air Force, and completed his service with the rank of lieutenant colonel. He earned a bachelor's degree in civil engineering and a master's degree with specialization in planning systems from the Technion – Israel Institute of Technology. He studied for a doctorate from the Hebrew University of Jerusalem for three years, but did not complete it.[1]
