Guilhem Lavaux, Ph.D.

Guilhem Lavaux is a permanent CNRS scientist at the Institut d’Astrophysique de Paris. Before this, he was a CITA National Fellow at the University of Waterloo and Associate postdoctoral researcher at the Perimeter Institute for Theoretical Physics. He was also a Postdoctoral researcher at the University of Illinois at Urbana-Champaign, which included two long visiting researcher positions at Caltech and at Johns Hopkins University. He was a recipient of a 4-year fellowship for the bachelor program. He earned his Master in theoretical physics from the Ecole Normale Supérieure and received his doctoral degree from the Université Paris-Sud (now Paris-Saclay) for his work conducted at the Institut d’Astrophysique de Paris. He works on modeling of the dynamics of the Universe, the exploration of new statistical tools to constrain cosmological parameters. He stimulated, for cosmology, the use of cosmic voids, the development of forward modeling techniques and new machine learning formulations. He was granted an early career research award by the ANR to stimulate the scaling of Bayesian inference technique in cosmology.
