Personal Biography

My research explores principles of light-matter interaction in the quantum optical and semiclassical regimes. In this context, I develop protocols for quantum control and quantum sensing. My research has predicted topological effects in Bosonic systems, explained the structure of disordered exciton-polaritons, and developed novel quantum control methods of Floquet many-body systems. In my most recent line of research, I have developed the Photon-resolved Floquet theory, an extension of the common Floquet theory that can track the photon exchange with an external driving field, and showcased its benefit for spectroscopic quantum sensing.
