I am a 5-th year (final year) Ph.D. student in the physics department at the University of Michigan, Ann Arbor. Before that, I received my Bachelor's degree from University of Science and Technology of China in 2019.
My Ph.D. research focus on using machine learning methods, including reinforcement learning, generative models, foundation models to deal with optical physics problems, including the fast surrogate simulation of photonics structures as welll as their inverse design. My advisor is Prof. L. Jay Guo.
I am looking for a full-time job position on foundation models, large language model, machine learning engineering. Feel free to contact me if you are interested!

under review, 2023
arXiv
We developed OptoGPT, the first foundation model for optical thin film structure inverse design. After being trained on a large dataset of 10 million optical thin film designs, OptoGPT demonstrates remarkable capabilities including: 1) autonomous global design exploration, 2) efficient designs for various tasks, 3) the ability to output diverse designs, and 4) seamless integration of user-defined constraints. We believe OptoGPT is a major leap towards accelerating optical science with foundation models.
