I am working on theoretical Cosmology, with a focus on understanding how large-scale cosmological structures arose from quantum fluctuations in the primordial universe. By doing so, the hope is to learn more about the physical conditions that prevailed in the early universe, and to test physics at energy scales that are much larger than what can be probed in particle-physics experiments, questioning both the foundations of quantum mechanics and the nature of gravity.
