Research highlight

I study strongly correlated quantum matter by probing its dynamical properties and many-body entanglement. Recently, my work has focused on the nonlinear dynamics of quantum many-body systems, laying the theoretical foundation for new experimental protocols that can reveal hidden phases of matter.
