About me

Last updated on Jul 7, 2025.

I am a third-year PhD student at the Paul G. Allen School of Computer Science & Engineering at the University of Washington. I feel very fortunate to have worked 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 reinforcement learning from human feedback (RLHF), RL theories, and LLM reasoning.

For Summer 2025, I am working as a research intern at Apple, Seattle, under the supervision of Dr. Lefan Zhang and Xuan Kelvin Zou. 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 my undergraduate and secondary school years, I participated actively in the Olympiad in Informatics and ACM-ICPC.
