I'm manager of the Special Projects Team in the Wolfram R&D deparment. We develop very interesting areas such as Geography, Astronomy or the languages of physical quantities and dates. I'm a physicist by training, specializing in General Relativity, and I've always enjoyed combining mathematical, numerical and computer algebra tools to study any problem. In particular, I've worked on topics such as Criticality in Gravitational Collapse, Perturbation Theory, Gravitational Radiation, or the formulations of the Einstein equations. I also started the xAct suite of Tensor Computer Algebra packages in Wolfram Language to perform all those computations, and now regularly used by many other authors.
