Sandro Tacchella

Assistant Professor in Astrophysics, Kavli Institute for Cosmology, Cambridge, Department of Physics, University of Cambridge
Sandro Tacchella is an astrophysicist working at the Department of Physics (Cavendish Laboratory) and at the Kavli Institute for Cosmology of the University of Cambridge. Before joining the University of Cambridge in 2022, he was Assistant Professor at the Physics Department of UNIST in Ulsan, Korea. From 2017-2021, he was a CfA Fellow at the Harvard-Smithsonian Center for Astrophysics in Cambridge, USA. He has received his Ph.D. from ETH Zurich (Switzerland) in 2017.

Sandro's long-range scientific goal is to understand the physics of the formation and evolution of galaxies and black holes across cosmic time. Specifically, he investigates the physical mechanisms that govern the formation of the first galaxies in the early universe, the buildup of the bulge and disk components in galaxies, and the cessation of star formation in massive galaxies. He exploits cutting-edge multi-wavelength observational data obtained with some of the most advanced telescopes on ground and in space. He uses and develops analytical and cosmological numerical models to shed light on the physical properties of galaxies. Sandro is also heavily involved in the new James Webb Space Telescope, playing a key role both in the data processing of the NIRCam instrument and in projects aimed at detecting galaxies formed in the early Universe and at characterising their primeval properties.
