About Me
Hi, I’m Yongzheng Dai. I am a fourth-year Ph.D. Candidate in Operations Research, ISE, OSU, supervised by Dr. Chen Chen. I completed my B.S. in Math at Beijing Jiaotong University in June 2020. My research interests are in large-scale optimization problems and mixed-integer (nonlinear) programming problems, where my research focuses on utilizing special problem structures and designing efficient (parallel) algorithms for solving related (NP-) hard problems. Specifically, I am interested in
- Design (parallel) methods to improve solvers for MIPs and MINLPs
- Develop efficient mixed-integer models for large-scale real-world problems
- Leverage cutting-edge methods for MIPs to tackle NP-hard problems
I am on the job market!
