I am an assistant professor at the University of Maryland.
I have a joint appointment between the Physics Department and the Center for Scientific Computation and Mathematical Modeling.

I am currently supervising three postdocs: Chad Galley, Frank Herrmann and Anil Zenginoglu; one graduate student (Physics): Enrique Pazos (moving to Georgia Tech as a postdoc in the fall of 2009) and one undergraduate honors student (Computer Science and Math): John Silberholz.

We have a rather broad spectrum of research interests. Some topics we work on are: numerical modeling of sources of gravitational waves (black holes and neutron stars), perturbation theory for black holes, effective-field theory methods for Post-Newtonian expansions, high order and spectral methods in complex geometries, scientific and parallel computing, general purpose graphics processing units.

Our work is possible due to the generous support of the National Science Foundation (Gravity Program, Physics at the Information Frontier, and the TeraGrid), NASA (Small Business Technology Transfer), NVIDIA Corporation (Professor Partnership Award) and the University of Maryland.

About myself:

I got my Ph D from my home country (Argentina) in 2000, year in which I moved to the States. Before joining UMD I spent time at Penn State, LSU and Cornell. Now I live in Washington, DC. Besides the beauty of DC, UMD is a very good university to be in, the Physics Dept. at UMD is currently ranked # 13 in the country, CSCAMM is a top center, and other depts I work with are equally or better ranked. The whole campus is vibrant with extremely talented people.

I previously supervised Nils Dorband, who is currently a postdoc at the Albert Einstein Max Planck Institute in Golm, Germany. Nils' Ph D thesis is available here.

I am a referee of Physical Review Letters, Physical Review D, Classical and Quantum Gravity, Living Reviews in Relativity, Journal of Computational Physics, Journal of Scientific Computing, Journal of Hyperbolic Differential Equations, Astronomy and Astrophysics Journal, American Journal of Physics, Modern Physics Letters A, and a reviewer for Mathematical Reviews.

I have reviewed/served in panels for the National Science Foundation and the Department of Energy.

Papers that I have co-authored have been chosen by the Editorial Board of Classical and Quantum Gravity among the "highlights of years 2006-2007"; 2005-2006, 2004-2005 and 2003-2004.

At UMD I am a member of the campus High Performance Computing Committee.
