About Me

I am a Staff Scientist in the Observational Cosmology Group at Caltech as of August 2016. I am an experimental cosmologist and an observational extragalactic astronomer. My main research interests are: the physics of the early Universe, Inflation, the primordial gravitational wave background, and reionization, as probed by Cosmic Microwave Background (CMB) polarization measurements; the origin of the Cosmic Infrared Background (CIB); the evolution of distant massive galaxies, both star-forming and quiescent; the physical processes responsible for active galactic nucleus (AGN) emission and their interplay with the star-forming activity of host galaxies. These science goals have been driving and complementing my interests in astronomical instrumentation over the past decade (Rome -> Cardiff -> Pasadena).

SPIDER is a balloon-borne experiment designed to search for the primordial gravitational waves predicted by inflationary theories by means of measuring their imprint on the CMB as an extremely faint curl-mode of polarization.

BLAST is a balloon-borne experiment designed to study star formation in our Galaxy and in distant galaxies. BLASTPol studies magnetic fields in galactic molecular clouds through the polarized submillimeter emission from aligned dust.
