- 自己紹介
- He is a Specially Appointed Associate Professor at the Research Institute for Synchrotron Radiation Science (HiSOR), Hiroshima University, Japan. He received his Ph.D. in Chemistry from the University of Lorraine, France, in 2017, specializing in synthetic organic and supramolecular chemistry. From 2019 to 2020, he conducted postdoctoral research at the University of Lorraine, focusing on the synthesis of functional polymers using photo-induced RAFT polymerization.
He joined HiSOR, Hiroshima University, in 2021. His research integrates organic, supramolecular, and polymer chemistry with synchrotron radiation spectroscopy to investigate the structures and conformations of biomolecules, macromolecules, marine-derived polymers, and polysaccharides, complemented by techniques such as NMR, FTIR, SAXS, etc. At HiSOR BL-12, he focuses on CD/SRCD-based structural analysis and the development of LC–SRCD systems for the real-time separation and conformational analysis of chiral biomolecules, with potential applications in environmental, biomedical, and industrial fields.
