I am currently a Ph.D. student in Sensing IntelliGence and MAchine learning lab (SIGMA) at School of Computer Science, Wuhan University (WHU), advised by Professor Yong Luo.
Previously, I obtained my Master's degree from School of Computer Science, Nanjing University of Posts and Telecommunications (NJUPT), where I was advised by Professor Qun Li.
In addition to my academic experience, I was fortunate to have spent a productive internship at ByteDance - Pico in 2022.
I am currently interested in Generative Models (especially Text-to-Image) & Reinforcement Learning from Human Feedback.
