Hi! I am an assistant professor of computer science at Northeastern University since Fall 2020. My work lies in the intersection of applied machine learning, statistical learning theory, and network analysis, with a particular emphasis on algorithms and generalization theories. I received my Ph.D. from Stanford, jointly advised by Ashish Goel and Greg Valiant. Meanwhile, I had the great fortune of working with Moses Charikar, Tengyu Ma, and Chris Ré's group. Before moving to Boston, I spent ten months as a postdoc at UPenn's statistics department. I received a B.Eng. from Shanghai Jiao Tong University.

My current focus is methodological and theoretical questions related to ML algorithms and graphs, including: (i) generalization and transfer: Understanding generalization for deep neural nets and transfer of large pretrained neural nets. (ii) learning from limited data: learning with noisy and weak supervisions, multitask learning, and data augmentation. (iii) graphs algorithms and learning on graphs: PageRank estimation, intervention on mobility networks, and generalization in graph neural networks.
