11.11.2025 PhD student – experimental astroparticle Physics at the University of Zurich The group of Professor Soares-Santos, at the University of Zurich (UZH), invites applications for a PhD student position. The group is engaged in data analysis, instrumentation, software development, and operations in state-of-the-art experiments in the field of cosmology with cosmic surveys and gravitational waves. In addition to carrying out some of the most precise cosmological measurements from galaxy clustering and weak lensing, we have led the most comprehensive searches for the electromagnetic (EM) counterparts of gravitational-wave (GW) events and contributed to the first GW-EM multi-messenger discovery. We are currently leading a multi-messenger cosmology effort, combining GW standard sirens…
