I am a relativistic astrophysicist, i.e., a physicist who uses Einstein’s theory of general relativity to describe and explain high-energy astronomical observations of black holes and neutron stars. To do this I combine analytical perturbative tools with numerical nonlinear simulations in which I solve the Einstein equations together with those of relativistic hydrodynamics or magnetohydrodynamics. I do this in the endless process of comparing theoretical results and predictions with astronomical observations. I am presently the Chair of Theoretical (Relativistic) Astrophysics at the Institute for Theoretical Physics (ITP) of the Goethe University of Frankfurt, Germany. I am also Senior Fellow at the Frankfurt Institute of Advanced Studies (FIAS).
Starting from October 2014 a team composed by Heino Falcke, Radboud University Nijmegen, Michael Kramer, Max-Planck-Institut für Radioastronomie, and myself has been awarded a Synergy Grant from the European Research Council (ERC). These grants represent the most prestigious and substantial form of funding in Europe and for the first time they have been awarded for an astrophysics proposal. More information can be found here.
Since November 2013 I am the Chair of (New)CompStar, a COST Action that brings together the leading experts in astrophysics, nuclear physics and gravitational physics to address this fascinating but challenging research area through an interdisciplinary approach.In addition to an innovative and well-defined research agenda, the network will provide a dedicated training program for a new generation of scientists with wide-ranging expertise and multiple skills oriented also towards knowledge transfer and innovation.
