I'm a third-year Ph.D. candidate at 
University of Illinois Urbana-Champaign (UIUC) advised by Jiaqi Ma, and I also work closely with Han Zhao. Currently, I'm an 
Anthropic AI Safety Research Fellow and a Ph.D. ML intern at 
Susquehanna International Group.
Previously, I've spent time at 
Amazon AWS AI Lab and 
National Institute of Informatics. I obtained my Master degree from UIUC and dual Bachelor degree from 
University of Michigan and 
Shanghai Jiao Tong University.
🔬 Research
Research-wise, I'm interested in the broad area of ML and AI, with the goal being to draw theoretical insights from practical problems and develop algorithms with provable guarantees and desirable properties such as efficiency, robustness, and fairness. Recently, my research focuses on understanding data, including the following three aspects:
- Data Attribution: Understanding how training data influences AI models.
- Data Curation: How to curate/generate/augment (synthetic) data that further helps models generalize?
- Data-Centric Privacy: Can above be done without compromising privacy when safety-critical or sensitive data is involved? This includes (differential) privacy, machine unlearning, etc.
Previously I have worked on graph neural networks with Jiaqi Ma and fast graph algorithms with Thatchaphol Saranurak. Generally speaking, I held (actually hold) a strong interest in theoretical stuffs that involves geometry.
