RESEARCH

We develop and apply advanced ultrafast laser spectroscopy to study the chemical reaction dynamics of the condensed-phase molecules. We track molecular dynamics from electronic and structural viewpoints throughout the chemical reaction with exquisite temporal resolution. Our particular interest rests on elucidating sophisticated molecular mechanisms that underlie the reactions of functional molecular systems such as proteins, molecular assemblies, and metal complexes. Based on new insights gained from our advanced spectroscopic approaches, we aim to establish a new avenue for studying chemical reaction dynamics.

Ultrafast dynamics of complex condensed-phase systems

We exploit ultrafast nonlinear spectroscopy, such as ultrafast Raman and multi-dimensional spectroscopy, to elucidate the molecular mechanisms that dictate the functional activation of the condensed-phase complex molecules.

Ultrashort pulse generation and manipulation

The advancement of ultrafast spectroscopy has always been together with that of ultrafast laser/photonics technologies. We develop novel light sources with the aim of expanding the limit of ultrafast nonlinear spectroscopy.

Ultrafast spectroscopy
at the single-molecule level

We are developing a novel methodology to probe ultrafast dynamics of single molecules to interrogate how spontaneous fluctuation characteristic of biological molecules regulates chemical reaction dynamics.
