Prof. Dr. Alejandro Ibarra



Academic Career and Research Areas

Prof. Ibarra’s (b. 1974) scientific research centers on theoretical elementary particle physics, in particular physics beyond the standard model, neutrino physics, super symmetry and astroparticle physics. He has worked on models of neutrino masses, rare leptonic decay, the indirect detection of dark matter and leptogenesis as a model for the origin of the universe’s matter/antimatter asymmetry.

Prof. Ibarra studied Physics at Universidad Complutense de Madrid and obtained his doctorate at Universidad Autonoma de Madrid in 2000. He did postdoctoral research at Oxford University and CERN in Geneva. Prior to joining DESY, the particle research center in Hamburg, he held a Ramon y Cajal postdoc position at the Institute for Theoretical Physics (IFT) in Madrid. In 2008, he became professor of theoretical elementary particle physics at TUM.
