Claude-André Faucher-Giguère Assistant Professor

Prof. Claude-André Faucher-Giguère has broad interests in theoretical astrophysics and cosmology, with particular emphasis on galaxy formation and evolution. Faucher-Giguère's research focuses on understanding the multi-scale physical processes that govern galaxy formation in the cosmological context, including star formation, galaxy-black hole co-evolution, galactic dynamics, and connections with the intergalactic medium and cosmology. He uses a multi-pronged approach including: large-scale numerical simulations, analytic modeling, and comparison with observational data.
