Nonequilibrium Dynamics
How do photoexcited carriers and collective excitations form, relax, and transport energy following ultrafast excitation?
Research
We bring together frontier physics, ultrafast spectroscopy,
precision instrumentation, and device engineering to investigate
light–matter interactions and quantum dynamics.
Research Vision
Exploring light–matter interactions and quantum physics through advanced spectroscopy
We investigate how charge carriers, excitations, and correlated quantum states emerge and evolve across ultrafast and low-energy scales. Our interests include nonequilibrium dynamics, many-body interactions, and low-energy electrodynamics in quantum and low-dimensional materials.
To address these questions, we develop and optimize complementary spectroscopic platforms that connect optical excitation, terahertz electrodynamics, cryogenic transport, and chip-integrated devices.
