Biography

I am a final-year Ph.D. student at the University of Tokyo, where I am very fortunate to be supervised by Prof. Masashi Sugiyama. I am also a Junior Research Associate at the Imperfect Information Learning Team, RIKEN Center for Advanced Intelligence Project, where I am also very fortunate to work with Dr. Gang Niu.

My research interests are in algorithms and theories of machine learning. Specifically, I am mainly interested in data-centric machine learning, reliable machine learning, and applications in foundation models.

Feel free to email me if you are interested in talking with me.
