About

Guillermo Lara

I am a postdoc at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) in Potsdam, Germany, in the Astrophysical and Cosmological Relativity department.

I am interested in using the tools of numerical relativity to study the phenomenology of the strong field regime of gravity in theories beyond General Relativity (GR). These may arise from high-energy completions of GR or be motivated by a dynamical explanation of the Universe’s self-accelerated expansion.

I did my PhD in Astroparticle Physics at SISSA (Trieste, Italy), supervised by Prof. Enrico Barausse. I am a member of the SXS Collaboration (Simulating eXtreme Spacetimes).
