Research focus:

Emergent phenomena in strongly correlated electron systems, including unconventional superconductivity, topological phases, and novel light-matter interactions. Development of experimental tools to investigate these systems: high-precision ARPES, on-chip THz spectroscopy, and nanofabrication techniques for 2D materials.
