I am a CERN fellow, in the Theoretical physics department, working on various aspects of theoretical cosmology, mainly focusing on the use of the large-scale structure of the Universe to test fundamental physics, theories of gravity, models of dark matter and other cosmological models. I am also interested in studying how we can use forthcoming radio surveys for cosmology.

At the moment I am particularly interested in gravitational waves. I am working on trying to understand if Primordial Black Holes can make up all or a part of the Dark Matter, and if GW from BH-BH mergers are in fact signatures of PBH Dark Matter. I am also interested in investigating the indirect detection of gravitational waves by using observations of the large-scale structure of the Universe.

I use observations of the clustering of structures across cosmic time to test cosmological models and theories of gravity on a wide range of scales. My main current interests include redshift-space distortions, baryon acoustic oscillations and the integrated Sachs-Wolfe effect. In particular, at the moment I am interested in how to model the n-point galaxy correlation function on very large scales, including geometrical and General Relativistic effects, and how to use galaxy clustering to test a variety of cosmological models and parameters.

Before my current position, I was a Marie Skłodowska-Curie fellow at the University of Barcelona, in the group of Prof. Licia Verde, and before that, a Postdoctoral Fellow at Johns Hopkins University, working with Prof. Marc Kamionkowski, Prof. Alex Szalay and Prof. Joe Silk on several aspects of theoretical and observational cosmology, in particular on primordial black holes, the early universe and redshift-space distortions analyses.

My collaborators network


I am the co-founder of the Spin-Foundation, an initiative that aims to fund scientific and technological companies owned and directed by scientists. The profits generated by companies started within the Spin Foundation will be invested in fundamental research and grants for researchers.

Within the Spin Foundation, 

I am the director of the Island Institute, a project of the Spin Foundation, a virtual new institute for cosmology.

The mission of the institute is to advance astrophysical research by building a strong international group of researchers who can collaborate in a flexible and creative environment, well funded and free from bureaucratic obligations, so that they can focus on innovative and visionary scientific projects.
