Outline of Annual Research Achievements

Through the JSPS Postdoctoral Fellowships program, I collaborated with Professor Chihaya Adachi at Kyushu University, leading to the publication of 6 SCIE papers in 2024 to 2025. Among these, the research most closely aligned with the objectives of the JSPS program was published in Nat. Commun. In recognition of its significance, we were invited to contribute to the Behind the Paper section of Nature Publishing Group’s Research Communities, where we provided insights into our findings. As of September/October 2024, this highly cited work ranked in the top 1% of the Physics field based on citation thresholds for its publication year. Additionally, in 2025, we harnessed machine learning to design high-performance organic light-emitting materials, culminating in a publication in Sci. Adv..
