My field of research lies at the interface between numerical and mathematical relativity. Related to the hyperboloidal problem, which I approach with conformal compactification methods, I am interested in hyperbolic gauge conditions for 3+1 formulations of General Relativity and the description of black hole geometries using trumpet slices.

As founding member of the Hyperboloidal Research Network I aim to make the use of hyperboloidal foliations available to the numerical relativity community, while making progress in its application to simulations of compact binary coalescences.

I did my PhD at the University of the Balearic Islands (Mallorca, Spain). Then I held a postdoctoral position at Cardiff University (United Kingdom), and currently I am postdoc and invited professor at Instituto Superior Técnico, University of Lisbon (Portugal).
