I was born in Argentina, where I studied up to obtaining a PhD from the National University at La Plata. After several fellowships (Sussex University, Inst. for Radioastronomy, Princeton University, Lawrence Livermore Natl. Lab.) and long stays in Italy, I started a new group on high-energy astrophysics in Barcelona. I have received several scientific awards (among them, the Chinese Academy of Science Senior Visiting Professorship, the Friedrich Wilhelm Bessel Award of the Humboldt Foundation of Germany, the Shakti Duggal Award on Cosmic Ray Physics of the International Union of Pure and Applied Physics, and the Guggenheim Fellowship). I have published 220+ papers, which have  12000+ citations. These papers can be accessed from ADS (http://bit.ly/1f9pno4). I edited 7 books. I became Director of the Institute of Space Sciences in March, 2016.

Research interests

The familiar sights of peacefully shining stars would be replaced by something extreme and variable should you look with gamma-ray eyes. You would be glancing at the most energetic phenomena known in astrophysics: accreting masses around black holes, pulsars, close binaries, regions of stellar formation, explosions of supernovae, and others. I develop theoretical models for these scenarios, and test them with observations using ground-based telescopes and satellites. My research group hosted about 30 scientists and published more than 250 papers since its foundation in 2006. My research focuses on compact objects and cosmic rays. My earlier research includes gravitation and cosmology; particularly, scalar-tensor theories and non-minimal couplings, scalar dark matter, boson stars, gravitational lensing, and wormholes. I published several papers on all these topics.
