Assistant Professor in the Galileo Galilei Physics and Astronomy department at the University of Padova, 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 fellow in the Theoretical physics department at CERN; before that, 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. During my first postdoc I was at the California Institute of Technology and NASA JPL, working within the group of Dr. Olivier Dore.

Johns Hopkins University
For my second postdoc I was Postdoctoral Fellow at Johns Hopkins University, where I worked with Prof. Marc Kamionkowski, Prof. Alex Szalay, and Prof. Joseph Silk; I used 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 interests included redshift-space distortions, baryon acoustic oscillations, the integrated Sachs-Wolfe effect and gravitational waves, in particular in relation to the model where primordial black holes comprise the dark matter.
NASA JPL &
California Institute of Technology
During my first postdoctoral position I worked at NASA JPL and the California Institute of Technology, under the supervision of Dr. Olivier Doré, on the Large Scale Structure of the Universe. In particular I worked on how to model the galaxy correlation function on large scales, including general relativistic and geometry effects; this is going to be a fundamental part of future cosmological analyses that will be performed with forthcoming and planned galaxy surveys such as PFS, DESI, LSST, Euclid, WFIRST and the SKA. I used precise models of galaxy clustering to test cosmological models and their parameters, including models for gravity, dark matter and the primordial universe.
Institute of Cosmology & Gravitation,
University of Portsmouth
I obtained my Ph.D. from the Institute of Cosmology and Gravitation (ICG) at the University of Portsmouth, in England, working under the supervision of Prof. Will Percival on tests of cosmological structure growth. In particular, I focused on Redshift-Space Distortions on large scales: we developed and tested a formalism that allows the inclusion of galaxy pairs with wide angular separation, and then applied it to a real data analysis. At the ICG I also worked with Dr. David Bacon on how to use forthcoming radio surveys to perform cosmological studies; this granted me the participation to the cosmology working group and the planning of future radio surveys.
Istituto Nazionale di Astrofisica
Following my graduation, I had a fellowship at the Astronomical Observatory of Padova under a contract with the National Institute of Astrophysics (INAF), to work with Prof. Gianfranco De Zotti on the ISW.
M.Sc. in Astronomy
University of Padova
I completed my Master of Science in Astronomy in Italy, at the University of Padova, under the supervision of Prof. Sabino Matarrese and Prof. Giuseppe Tormen. My thesis was based on a study of the integrated Sachs-Wolfe (ISW) effect via the correlation of NVSS radio sources with CMB maps.

I am an assistant professor at the University of Padova, working on the interface between theoretical and observational cosmology; most recently, I have been working on multi-messenger cosmology, i.e., the combination of gravitational waves and photons (at different wavelengths) to study cosmological models and early universe physics. I also use observations of the clustering of structures across cosmic time to test cosmological models and theories of gravity on a wide range of scales. More recently I started being interested in the applications of machine learning to cosmology.
My main current interests include: gravitational waves, large-scale structure of the Universe, cosmology with radio surveys, and how we can use all these observations to test cosmological models and fundamental physics. I am part of the cosmology working group of several galaxy surveys, both in optical and radio, and gravitational wave experiments.
