Hi! I am a postdoctoral researcher at Columbia University, hosted by Toniann Pitassi and Richard Zemel. Previously, I completed my Ph.D. in Computer Science at Harvard University under the guidance of Cynthia Dwork. Prior to Harvard, I received a B.Sc. in Mathematics and Applied Mathematics from Chu KoChen Honors College, Zhejiang University.
My research interests mainly lie in the foundations of reliable and responsible machine learning. In particular, I develop formal frameworks to address algorithmic and societal challenges in modern data science, especially about uncertainty quantification, risk control, algorithmic fairness, and model robustness.
