About Me

I work at ByteDance Seed, as a senior research scientist and a member of TopSeed program. I am working on advancing reasoning capability (like O1) of Large Language Models (LLMs) and Agent foundation model. We are hiring research interns and looking for academic cooperation, please feel free to email me at wanjun@bytedance.com

Prior to that, I worked at Huawei Noah’s Ark Lab as a research scientist and a member of Huawei TopMind program. I received my Ph.D. degree from the School of Computer Science and Engineering in Sun Yat-sen University (SYSU), as a member of joint Ph.D. program between SYSU and Microsoft Research Asia (MSRA).

As a joint Ph.D. student, I was advised by Dr. Ming Zhou, Prof. Jian Yin and Prof. Jiahai Wang. I was a research intern in the Natural Language Computing Group of MSRA, and was mentored by Dr. Nan Duan

I won the Microsoft Research Fellowship Award (11 outstanding Ph.D. in Asia-Pacific area each year) in 2021, and is selected as a member of Huawei TopMind program in 2023.

I published over 40+ papers in top-tier AI conferences and journals, including NeurIPS, ICLR, ACL, EMNLP, TASLP, NAACL, AAAI, IJCAI, ISSTA, etc.
