Assistant Professor

Research Interests:

Dynamical Materials Control with Light

I work on experimental condensed matter physics. My previous research focused on light-induced far-from-equilibrium phenomena, steady-state electrodynamics of strongly correlated materials, and the discovery of unconventional superconductors. My future research plans include coherent phonon control in unconventional superconductors, ultrafast imaging of optically stabilized quantum phases, and high precision optical spectroscopy and dynamical materials control in low dimensions.
