I am a final-year undergraduate at Renmin University of China, working under the supervision of Prof. Jun He (Renmin University) and Prof. Hongyan Liu (Tsinghua University). During my visit to HKUST, I was supervised by Prof. Qifeng Chen researching about VideoDPO. Now I am working with Dr.Junliang Guo at ML Group, MSRA.
My research interests include generative models, AI-generated content, video generation, and talking head generation. I also keep up with a wide range of research in AI, having explored papers on topics such as MLLM, diffusion models, PEFT, and RLHF, which I have saved here and here.
I am actively I am actively seeking 25 fall PhD opportunities. If my work aligns with your interests, please feel free to reach out to me.
You can find my CV here.
