Dr. Masahiko Nakase is a specialist in nuclear chemical engineering who works at the Institute of Innovative Research, Tokyo Institute of Technology (Tokyo Tech). His academic research spans the entire NFC from the front-end to the back-end. His primary research areas include Actinide chemistry in both separation and waste fabrication. He studied mechanical engineering at Tokyo Tech as a bachelor’s student. He studied nuclear reactor physics in a master’s course. In a doctoral course, he developed a high-performance contactor that induces a unique vortex inside. In the postdoctoral period, he synthesized some extractants for separating trivalent actinide from HLLW and external stimuli-sensitive hydrogel adsorbents, and aqueous chemistry was implemented at SPring-8, JAEA. He also worked for Am oxidation and separation work in INL. Finally, he got a job at Tokyo Tech and expanded his research to other element separation and Fukushima waste studies. In 2023, he was appointed associate professor, established the 'Nuclear Energy System Laboratory,' and began innovative digital studies. His current research interests are focused on human-in-the-loop machine learning. This cutting-edge approach aims to accelerate actinide chemistry study in Japan and streamline the experimental process, thereby reducing costs and effort.
