Our research focuses on developing two-dimensional infrared (2D IR) spectroscopy and its application to understanding the structure and (fast) dynamics of diverse targets ranging from small molecules to material-based macromolecular complexes. Some of our research topics are:
1. Developing advanced data analysis methods to interpret the complicated dynamics of molecular systems in the presence of fast dynamics including chemical exchange, spectral diffusion, and energy transfer
2. Understanding fast protein-solvent (water) interaction mainly mediated by H-bond dynamics
3. Improving the sensitivity of 2D IR spectrometer by designing advanced experimental equipment to obtain high-quality 2D IR spectra for low absorption samples
4. Developing new 2D IR experimental methods suitable for studying solid-phase molecular complexes with rough surfaces, such as metal-organic frameworks (MOFs) and perovskite films, by eliminating spectral contamination by scattered light
5. Making 2D IR spectroscopy to be widely used for general purposes.
