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.
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, algorithmic fairness, and model robustness.
