My research is focused on the open problems of particle physics and the fundamental interactions.
You can find my publications on inSpire and Google-Scholar.
Recently, I have been working at the interface between two main topics: Scattering Amplitudes and Effective Field Theories, with and without gravity.
A great challenge is to understand the origin of the four fundamental forces of nature, and possibly to unveil an underlying unifying principle. Related questions are the origin of masses, i.e. the electroweak symmetry breaking mechanism of the Higgs sector, and the hierarchy problem* of the observed scales.
*one of my favorite divulgative explanations of the hierarchy problem is provided by this quote from Cliff Cheung: "When you lift a paper clip off a table with a small magnet, you're accomplishing a remarkable feat: the tiny magnet is overcoming the gravitational pull from the entire Earth. Why does gravity seem so weak compared to electromagnetism and the other fundamental forces of nature? This vast discrepancy in scale—how a small magnet can beat out a whole planet—is related to what physicists call the hierarchy problem".
