About

I specialize in quantum many-body phenomena, using numerical simulations to study complex quantum systems. My research focuses on superfluidity, non-equilibrium dynamics, and coherent light-matter interactions. I am modelling quantum behaviours within the driven Bose-Hubbard framework and developing efficient quantum circuits for simulating complex many-body Hamiltonians on NISQ systems.
