Currently, I am a Ph.D. student in the School of Computer Science, Beijing University of Posts and Telecommunications (BUPT), and a member of the iDMG research group, supervised by Prof. Yingxia Shao.

My research focuses on ML systems, with an emphasis on large-scale recommendation systems, distributed graph neural network training, and efficient LLM training.
