Our research group combines data from several cosmological probes, such as the Cosmic Microwave Background, galaxy clustering and weak gravitational lensing, to test and constrain our cosmological model and the physics of galaxy formation. We are involved in several on-going and future cosmological surveys with a particular focus on ACT, LSST, and SO, and use these data to probe the key ingredients of our cosmological model such as Dark Energy, Dark Matter, and Inflation. To optimally benefit from these exciting, high-precision experiments, we are also developing novel analysis techniques for cosmological data, making use of methods such as machine learning.
