Graduate student, the University of Tokyo
Machine learning, computer vision, quantitative research
I'm a graduate student in bioengineering at the University of Tokyo, with a background in computer science and AI from the Chinese University of Hong Kong. My current research is in time-resolved magneto-optics and spin dynamics; I also work across machine learning, computer vision, and quantitative research. In September 2026 I interned as an engineer at Money Forward i and at M3.
