Profile
I am a Ph.D. student majoring in Computer Science at Shanghai Jiao Tong University, a member of the Wen-Tsun Wu AI honorary doctoral class. I obtained my B.Eng. majoring in CS at SJTU as a member of the ACM Honors Class, an elite CS program for the top 5% of talented students.
Experiences
- I am a Ph.D. researcher, advised by Prof. Hongyuan Zha and Prof. Junchi Yan.
- Focus on utilizing machine learning methods to solve combinatorial optimization problems in the real world.
- I am a research intern, advised by Prof. Xijun Li and Prof. Jia Zeng.
- Focus on using deep learning approaches to improve the solving of mix-integer programming (MIP).

Projects
Machine Learning for Combinatorial Optimization Problems
- We maintain a list of resources that utilize machine learning technologies to solve combinatorial optimization problems (ML4CO), which has gained more than 1,000 stars on Github.
Generalized Traffic Signal Control System
- We propose a novel meta-RL framework GeneraLight for traffic light signal control models, which can significantly improve their generalization ability to different environments.
Learning to Simulate
- We focus on reducing the gap between simulator and the real world, finding solutions to different problems.
City Traffic Simulator
- We Built a city traffic simulator, serving reinforcement learning algorithm as a multi-agent reinforcement learning environment.
Shared Bike System in Urban Computing
- Focusing on transfer learning and spatial-temporal analysis in shared bike system, I wrote a paper proposing a model combined with principle component analysis, discrete wavelet transform and attention mechanism.
Mx Compiler
- I designed a compiler implemented in Java from scratch, translating a Java-and-C-like language to NASM, and implemented optimizations for the compiler, faster than gcc O1 on some test sets.
Shor Algorithm
- A simple implement of shor algorithm in quantum computing, written by a new quantum language called Q#.
