Research Experience
- Position: Assistant Professor
- Affiliation: School of Artificial Intelligence (SAI), The Chinese University of Hong Kong, Shenzhen
Education
- Ph.D. Advisor: Professor Cédric Josz
Background
- Research interest lies in nonconvex optimization, differential equations, semi-algebraic geometry, with applications in low rank matrix recovery, deep neural networks, and large language model reasoning.
Miscellany
- I am actively recruiting PhD students who are interested in optimization for machine learning, nonconvex/nonsmooth optimization, or LLM reasoning. Strong mathematical background and solid programming skills are important; prior research experience is a plus.
