I'm working in the field of theoretical cosmology, studying in particular gravitational wave signals and their potential to probe the characteristics of both the early and the late-time Universe.

I'm a professor at the University of Geneva and Staff member at CERN, on leave from CNRS, France.

I'm a member of the LISA Consortium, I founded the LISA Cosmology Working Group and I'm coordinating the Science Investigation Work Package of the LISA Science Group.
