- Fundamental aspects of General Relativity
- Alternative theories of gravity
My research focuses on the strong field regime of classical gravity, within the framework of Einstein’s theory of General Relativity, and alternative theories of gravity. Part of my interests involves fundamental aspects of the theoretical framework, whereas other part incorporates applications to high-energy astrophysics. For my purposes, I usually combine analytical techniques such as perturbation theory, energy estimates, and analysis of dynamical systems, for instance, with numerical techniques such as finite differences, finite volumes, and shock capturing methods. I am involved in a number of collaborations with a diverse group of researchers. In particular, I am part of the Computational Relativity Collaboration, where I contribute to the development of novel numerical relativity tools and methods.
