José Martin-Garcia External Research Affiliate

José's background is Theoretical Physics, and his PhD thesis studied the fascinating properties of the process of formation of the smallest possible black holes, in the framework of Classical General Relativity. This work required the manipulation of nontrivial tensor equations, which José did with Mathematica, starting what would become two major interests of his since then: the development of computer algebra tools to manipulate large tensor expressions, and the Wolfram Language. José's work in relativity evolved towards the study of formulations of Einstein's equations, looking for appropriate formulations for numerical evolutions of black-hole binary spacetimes. This was of vital importance to the study of generation of gravitational wave signals in black hole collisions, and him and his collaborators succeeded in 2004 identifying a technique that would allow the first stable evolutions of black hole binaries. With the powerful tensor tools José had developed by then, he also studied high-order perturbations of spacetimes and developed large collections of identities for the Riemann tensor, now frequently used when developing alternative theories of GR. In 2010, he started working for Wolfram Research, and since then, has been fortunate to work on a variety of exciting projects, including Geography, the framework for dates and time, the language for units, quantities and their uncertainty, and many other projects. José also regularly participates in discussions on the design of the Wolfram Language itself, one of the most interesting parts of working at Wolfram.
