My mission is to optically explore the mechanisms of quantum and nanomaterials and translate this knowledge into practical technologies. Currently, my research is focused on investigating nanoparticle-based scintillation using time-resolved X-ray luminescence. This understanding aims to drive the development of fast and thin scintillators, ultimately reducing personnel X-ray exposure in the medical field.

In another project, I am working on on-chip UV spectroscopy with the goal of developing a miniaturized spectrometer in the UV regime. This effort aims to provide compact and efficient analytical tools for characterizing biomaterials, such as proteins and DNA. Through a series of research projects, my goal is to translate the knowledge gained from studying quantum and nanomaterials into tangible technologies in various fields.
