prof_pic.jpg

I am a second-year M.Sc. student in the PALM Lab @ Southeast University (SEU), supervised by Prof. Hongsong Wang, currently a Research Intern at Tencent Hunyuan. I am also collaborating remotely with Prof. Ming-Hsuan Yang at UC Merced. Previously, I was a Research Intern at Tencent’s Youtu Lab. Prior to that, I was a remote visiting student at LV LAB @ Singapore Management University (SMU), where I worked closely with Prof. Pan Zhou. I received dual bachelor’s degrees (B.E. in CS, B.Sc. in Math) from Shenzhen University (SZU) in 2024, where I started research with Prof. Can Gao.

My research interests mainly revolve around RLHF, RLVR, AIGC, and 3D Human Modeling. I am actively seeking (1) Ph.D. positions for Fall 2027 and (2) other research collaborations related to RL or AIGC. Feel free to reach out via 📧 xiaofengtan@seu.edu.cn or 💬 WeChat: txf_06_20 . I'd be happy to connect 😊. And if you'd like to talk about Doraemon 😺, that works too. For more details, please check my CV / 中文简历.
