Research

    My research focuses on primordial cosmology. Currently I am exploring new physics effects in the earliest stage of the Universe, by looking into their imprints in cosmological observables. In particular, I am interested in applying the boostrap approach to study the theoretical aspects of cosmological correlators, and the phenomenology of primordial non-Gaussianity.
