I am an Assistant Professor of Computer Science at Northeastern University, Boston. My research interests lie at the intersection of machine learning, algorithms, neural networks, learning theory, and language modeling, including topics such as:

I received my Ph.D. in computer science from Stanford and my B.Eng. in computer science from Shanghai Jiao Tong University. I spent about a year as a postdoc within the statistics and data science department at University of Pennsylvania. For more information about me, please look at my cv.

I enjoy working on technically challenging problems, and strive for broader impacts by creating new knowledge and improving access to education. I support accessible and reproducible research. See our experiment codes on GitHub. Here is a list of my recent activities.
