I am an experimental physicist specialised in neutrino physics and detector technology. I graduated at the Univ. of Sevilla and I got my PhD at the Universitat Autònoma de Barcelona working at an experiment at CERN (Switzerland). I worked as researcher at the Deutsches Elektronen Synchroton (DESY) in Hamburg (Germany) and at the Max Planck Institute fur Kernphysik in Heidelberg. I have worked at several particle physics experiments like ALEPH at CERN or HERA-B at DESY. In 2002 I joined the K2K experiment in Japan and since then I am working on neutrino physics as the leader of the group at IFAE. I participate in the T2K experiment in Japan where I made major contributions to the experiment construction and main results, mainly the first explicit appearance result in neutrino oscillations. I was awarded with the Breakthrough prize on fundamental physics in 2016, together with the K2K and T2K collaborations for the discovery of neutrino oscillations.
I am interested in fundamental physics research to unveil the inner secrets of nature. This is my main research line. But, at the same time, I am also interested in the development of new particle detection technologies. I believe that breakthroughs in research comes both from the ingenuity of researchers and the invention of new technologies. I have been keeping these two interests during my research career contributing with hardware development and physics analysis to all experiments I participated. I am also very interested in outreach. Together with members of my group, we have promoted several initiatives: talks at secondary schools, cloud chamber detector for science ferias, participation BIYSC and Bojos per la física programs.
