I was born in Buenos Aires, where I studied up to obtaining my doctoral degree in physics from the National University at La Plata, working on cosmology and astrophysics of extended gravitational theories. After several years in fellowships around the world, I moved to the Institute of Space Sciences to start a research group on high-energy astrophysics in 2006. My research focuses on compact objects and cosmic rays. I have received several scientific awards including the Chinese Academy Presidential Fellowship, its 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, the Guggenheim Fellowship, and several others. I was Director of the Institute of Space Sciences 2016-2023, and Editor-in-Chief of the Journal of High Energy Astrophysics 2013-2023.

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. I develop theoretical models for these scenarios from a multimessenger perspective, and test them with observations using ground-based telescopes and satellites. My research focuses on compact objects -especially the physical understanding of pulsars, their classes, emission, wind nebulae, progenitors, and environments-, cosmic rays and their connection with star formation, and relativistic systems in our Galaxy. My earlier research includes gravitation and cosmology; scalar dark matter, boson stars, gravitational lensing, and wormholes. I published >300 papers on all these topics. My research group hosted 50+ scientists since its foundation in 2006. My website provides further details and links.
