As reported by the 'Top Chinese Community', Chen Lijie, a distinguished alumnus of Tsinghua University's renowned 'Yaoclass' and an assistant professor in the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley, officially embarked on a full - time journey with OpenAI in January 2026. His primary focus at OpenAI will be conducting research in the realm of mathematical reasoning. At present, he has taken an unpaid leave of absence from his faculty position at Berkeley.

Chen Lijie stands out as a preeminent scholar in the field of theoretical computer science. His academic prowess was evident early on when he clinched a gold medal at the International Olympiad in Informatics. During his doctoral studies at MIT, he made a groundbreaking contribution to the academic community by solving a computational complexity problem that had remained unsolved for nearly 50 years. With his addition to the OpenAI team, there is great anticipation that he will bring a fresh and distinctive perspective to the table, ultimately enhancing the deep reasoning capabilities of AI models.
