Welcome! My name is Lucas Pinol, I am a PhD student at the Institut d’Astrophysique de Paris (IAP), working on the physics of the early universe.

More precisely, I try to better understand the very first moment of the Universe by computing theoretical predictions of realistic models of inflation and reheating. These models can include many kinds of scalar fields (particles similar to the Higgs boson) with generic interactions, potential and kinetic, amongst them but also with Standard Model and Dark Matter particles. The theoretical predictions can then be compared to actual observations, such as the statistics of the Cosmic Microwave Background, the presence of Primordial Black Holes or a stochastic background of Gravitational Waves, etc., thus constraining the possible masses and interactions of the scalar fields.
The Universe is the most exciting laboratory for Particle Physics and Gravity, let’s study it!
