Welcome!
I am a postdoctoral researcher working under the supervision of Taiji Suzuki. I obtained my Ph.D. from the University of Tokyo, where I was fortunate to be advised by Masashi Sugiyama. I got my B.S. from Zhejiang University with major in Statistics.
Research Interests: the complexity of sampling and optimization.
Past Visits
I visited Prof. Sinho Chewi in May–June 2025 and Prof. Yitong Yin in November 2025.
