RESEARCH INTERESTS

I've always found gravity and its effects fascinating. This lead me into General Relativity; Einstein's beautiful theory which holds the clue (at least in the classical regime) to fully understand gravity. The equations governing the graviational system are so involved that to decipher their message in the most interesting cases (strongly gravitating-highly dynamical regimes) one must resort to numerical simulations. I have been working in the field of Numerical Relativity (the sub-branch of General Relativity studying how to obtain these numerical implementations) since 1994. Obtaining a numerical simulation of any physical system, but in particular one described by Einstein equations is far from being a straightforward task. A large number of issues must be contemplated in this enterprise and my interests cover all of them. From analytical issues to writing implementations to be run on supercomputers.
