Prof. Waxman is one of the world’s leading theoretical astrophysicists exploring ultra-high energy cosmic rays and neutrinos, and the explosions of massive stars.

Being the Chair of the Dept. of Particle Physics & Astrophysics at the Weizmann Institute of Science and former Chief Scientist of the Israeli Atomic Energy Commission, Prof. Waxman constructed a leading theory for the origin of ultra-high energy cosmic rays, a significant driver for the construction of giant neutrino detectors. He is the leader of an Israeli-American-German space mission, ULTRASAT, that will revolutionize our ability to study explosive events in the universe and enable us to answer fundamental open questions regarding the origin of the heavy elements and the explosion mechanisms of massive stars.
