Research interests

I am interested in the theory and phenomenology of gravitation. In recent years, my research activity has focused on the study of gravitational wave sources, such as black holes and neutron stars, as probes to study fundamental interactions: from gravity itself (testing general relativity against possible modifications), to nuclear physics (e.g. the elusive equation of state of neutron stars), to new fundamental fields and possible dark matter candidates. These studies involve different fields - from general relativity to gravitational phenomenology and data analysis, from astrophysics to cosmology, from nuclear physics to high-energy physics - employing different approaches (perturbation theory, post-Newtonian expansions, numerical relativity).
