About Me
Hi there! I am a Ph.D. candidate in the Department of Automation at Tsinghua University, advised by Prof. Keyou You.
My research interests lie at the intersection of Optimization, Machine Learning, and High-Performance Computing. I am dedicated to exploring the theoretical foundations of neural control and developing efficient solvers for large-scale optimization problems. Currently, I am also working on High-performance GPU solvers for optimization.
If you are interested in my research or have any questions, please feel free to contact me via email at lixc21@mails.tsinghua.edu.cn.
