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 in 2014/15, the Friedrich Wilhelm Bessel Award of the Humboldt Foundation of Germany in 2012, the Shakti Duggal Award on Cosmic Ray Physics of the International Union of Pure and Applied Physics in 2007, and the Guggenheim Fellowship in 2006). I have published 220+ papers, which have 10700+ citations. These papers can be accessed from ADS (http://bit.ly/1f9pno4) I edited 5 books.
