Hi there! I am a forth-year Ph.D. candidate at ShanghaiTech university’s PLUS lab, under the mentorship of Prof. Xuming He. Previously, I got my B.Sc. degree in 2022 from ShanghaiTech University. I also had the wonderful opportunity to spend time as a research intern at Shanghai AI Lab, supervised by Dr. Peng Gao. and a research intern at Tencent Youtu Lab, where I focus on post-training for multi-modal document understanding and coding agent. I’m currently a research intern at Tencent Hunyuan working on post-training for Omni model. My research interest includes Multimodel Learning and Data-centric AI. In pursuit of this goal, my current research work involves multimodal large language model, and post training with RL.
