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.

EXPERIENCE
2018-2020

CERN Fellow

CERN

CERN fellow in the Theoretical Physics department.

Focusing on Cosmology, Astroparticle Physics and Gravity.

2016-2018

Marie-Skłodowska-Curie fellow

University of Barcelona

I received a grant in the H2020 program of the European Commission to work as a Marie Skłodowska-Curie fellow at the University of Barcelona.

Working in the group of Prof. Licia Verde 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.

2014-2016

Postdoctoral fellow

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.

2014-2016

Postdoctoral Scholar

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.

 
EDUCATION
2008-2011

PhD

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.

2007-2008

INAF fellow

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.

2007

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.

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.
