Research Interests
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 transfer2. Understanding fast protein-solvent (water) interaction mainly mediated by H-bond dynamics3. Improving the sensitivity of 2D IR spectrometer by designing advanced experimental equipment to obtain high-quality 2D IR spectra for low absorption samples4. 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 light5. Making 2D IR spectroscopy to be widely used for general purposes.
