Pierre Boccard

PhD candidate in cosmology — CPPM / CNRS, Aix-Marseille Université. Voids, photometric redshifts, and the Vera C. Rubin Observatory (LSST).

I build the theory and the tools needed to turn cosmic voids — the giant empty regions between galaxy filaments — into a precision cosmological probe for the Vera C. Rubin Observatory.
