I am a first-year Ph.D. student in Computer Science at University of Illinois at Urbana-Champaign. I earned my dual master degree from Tsinghua University and Columbia University, and my bachelor from Fudan University.
I’ve previously worked on Data-centric ML and Trustworthy ML, with a particular focus on Large Language Models, and I’m always interested in exploring new and exciting machine learning topics. I value research that is, at the very least, empirically useful; ideally, grounded in theory; and, at best, elegant.
🚀 I am actively seeking a Research Scientist internship position for Summer 2025. Feel free to reach out if you believe there’s a potential fit.
