Research Topics

Photoexcited materials are found in every corner of our daily life, from optical sensors in cell phones to solar panels on rooftops... What decide the functionality of these materials are the behaviors of interacting electrons, elementary excitations and phases of matters generated during the photoexcitation.

To understand and control photoexcited materials, my research topics have spanned from studying equilibrium materials to investigating non-equilibrium phenomena, such as finding new optically-nontrivial materials, resolving light-induced ultrafast dynamics, inducing photon-driven phase transitions and ultimately actively manipulating the electronic and structural properties and correlations in the materials via orchestrated lasers.
