Since the early 1980s his main research interest has been particle astrophysics and cosmology, particularly astrophysical and cosmological tests of the standard particle-physics model, the standard Big Bang model, and general relativity. These included studies of cosmic puzzles such as the solar neutrino puzzle, the origin of cosmic rays and gamma-ray bursts, dark matter and dark energy. The research was done at the Technion, the University of Pennsylvania, the Institute of Advanced Study in Princeton, NASA’s Goddard Space Flight Center, the Institute of Astronomy, Cambridge, UK, and the European research centre, CERN in Geneva. In collaboration with various authors, he suggested the existence of cosmic backgrounds of energetic neutrinos from stellar evolution, supernova explosions, and cosmic ray interactions in external galaxies, the day-dight Effect in solar neutrinos, tests of neutrino oscillations with atmospheric neutrinos, gravitational lensing tests of general relativity at very large distances and the supernova-gamma ray burst-cosmic rays-mass extinction connection. His most recent work has been on a unified theory of cosmic accelerators, gamma-ray bursts, and cosmic rays. He published more than 150 scientific papers in these various fields in professional journals and gave more than 100 invited talks, published in the proceedings of international conferences. He won several scientific awards and served the Technion, Israel Defense Ministry, Israel Atomic Energy Committee, and numerous national and international scientific committees and advisory boards.

Edwin Dennis Kilbourne has spent his professional lifetime in the study of infectious diseases, with particular reference to virus infections. His early studies of coxsackieviruses and herpes simplex preceded intensive study of influenza in all of its manifestations. His primary contributions have been to the understanding of influenza virus structure and genetics and the practical application of these studies to the development of influenza vaccines and to the understanding of the molecular epidemiology and pathogenesis of influenza. His studies of influenza virus genetics resulted in the first genetically engineered vaccine of any kind for the prevention of human disease. The approach was not patented, and recombinant viruses from his laboratory have been used by all influenza vaccine manufacturers since 1971. A novel strategy for infection permissive influenza immunization has received two US Patents. Following his graduation from Cornell University Medical College in 1944, and an internship and residency in medicine at the New York Hospital, he served 2 years in the Army of the United States.
