I am a final year PhD student at CMU CSD, co-advised by Zico Kolter and Pradeep Ravikumar. I received my Bachelor's degree in computer science and applied math (double degree) from Peking University, where I was advised by Liwei Wang. I study machine learning theory and algorithms. My primary interest are representation learning and generalization theory, including statistical generalization and out-of-distribution (OOD) generalization. I am developing self-supervised methods for learning representations that are more controllable and interpretable than the prevailing black-box AI models, and applying these methods to various modalities. I also work on general statistical learning theory.

I am enthusiastic about mentoring students, especially students who just started doing research. Several of my past mentees have published their first ML papers at top venues, and been hired by top tech companies such as OpenAI and Amazon. For junior students: Please feel free to contact me by email if you are interested in working with me, especially if you want to work on representation learning, self-supervised learning, or generalization theory.
