Temi di ricerca

My research focusses on the foundational aspects of cosmology, such as the nature of dark matter, dark energy, gravity, and inflation.  I mainly work on testing cosmological models with experiments and observational data, such as from—but not only—weak lensing and galaxy clustering surveys.  My current effort aims at finding novel observables or combinations of known observables to exploit the large-scale structure information at its best.  At the moment, I pursue three different projects with this multi-wavelength, synergistic approach:

1. The multi-tracer technique, to overcome cosmic variance and detect primordial non-Gaussianity and relativistic effects on scales near and beyond the cosmological horizon.
2. The cross-correlation between gamma-ray anisotropies and direct gravitational probes of dark matter (e.g. clustering or lensing), to detect dark matter particles.
3. The use of radio cosmic shear in combination with traditional optical/near-IR weak lensing, to mitigate systematic effects and the spurious contamination from intrinsic alignments.

I am an active member of various international collaborations. In particular, I have Builder status in the Euclid Consortium (EC), responsible for the scientific exploitation the European Space Agency's Euclid satellite, and I am the current Chair of the Cosmology Science Working Group (SWG) of the SKA Observatory (SKAO). In the EC Theory SWG, amongst other things I coordinated the 'Dark Matter & Particle Cosmology' Work Package (WP) for about ten years, besides being part of its Editorial Board, and I current Lead of the 'Photo-z Clustering' WP of the Galaxy Clustering SWG.  I am also part of: the EMU radio-continuum survey collaboration; the MeerKLASS neutral hydrogen intensity mapping survey collaboration; the LOFAR Surveys Key Project; the SuperCLASS collaboration; and the proposed Wide-field Spectroscopic Telescope.
