Valle received his PhD at Syracuse University, New York, in 1982. He worked as a Research Associate at the Rutherford Appleton Laboratory, Oxfordshire, UK and as a visiting Professor at the Autonomous University of Barcelona, Spain. In 1987 he joined the University of Valencia where he is leading the Astroparticle and High Energy (AHEP) Group of IFIC (Instituto de Física Corpuscular) .
Valle has contributed significantly to the modern theory of neutrino mass. In a groundbreaking work with Joseph Schechter he has provided the first exhaustive discussion of the various mechanisms of neutrino mass generation (including the variants of the seesaw mechanism). The same authors also formulated the Schechter-Valle theorem demonstrating that an observation of neutrinoless double beta decay will necessarily imply neutrinos to be Majorana fermions and vice versa. He also contributed to the correct interpretation of the oscillations of solar and atmospheric neutrinos which led to the physics Nobel Prize 2015 awarded to Arthur B. McDonald and Takaaki Kajita. The discovery of neutrino masses and oscillations can be considered as the only firm indication of the incompleteness of the Standard Model of particle physics with important consequences also for astrophysics and cosmology.
