About me

Last updated on Feb 02, 2026.

I am a Staff Research Scientist at Meta Superintelligence Labs and a fourth-year PhD student at the Paul G. Allen School of Computer Science & Engineering at the University of Washington. I have been fortunate to work under the guidance of Professor Simon Shaolei Du since 2020. I also work closely with Professor Maryam Fazel.

My research focuses on machine learning and its theories, with an emphasis on reinforcement learning (RL) and large language models (LLMs). Currently, I’m researching RL theory and LLM reasoning (infrastructure, data curation, and algorithm design).

I was a research intern at Apple, Seattle, under the supervision of Dr. Lefan Zhang, Dr. Shang-Chen Wu, and Xuan Kelvin Zou from June 2025 to January 2026. I was a research intern at Microsoft Research, Redmond, under the supervision of Dr. Baolin Peng and Dr. Hao Cheng in Spring 2025, Dr. Yi Zhang in Summer 2024, and Dr. Beibin Li in Summer 2023.

I graduated from Yao Class, Institute for Interdisciplinary Information Sciences at Tsinghua University with a Bachelor of Engineering degree in 2022. My undergraduate thesis was jointly advised by Professor Simon Shaolei Du and Professor Yi Wu.

During undergraduate and secondary school, I actively participated in the Olympiad in Informatics and ACM-ICPC.
