About me

I’m a Research Scientist at Tencent Hunyuan in Beijing. Previously, I received my Ph.D. and B.Sc. degrees in Computer Science and Engineering from The Hong Kong University of Science and Technology in March 2026 and July 2022, respectively. My research was supervised by Professor Yangqiu Song and generously supported by the HKPFS award. I was also a visiting Ph.D. scholar at Johns Hopkins University, where I was supervised by Prof. Daniel Khashabi. Before that, I completed two Applied Scientist internships at Amazon in Palo Alto, where I worked with the Stores Foundational AI team and the Customer Search Experience team under the mentorship of Dr. Xin Liu, Dr. Qingyu Yin, Dr. Limeng Cui, and Dr. Chen Luo.

Research Interest

I’m mainly interested in research on large language models. My current work focuses on:

  • GUI/CLI Agents Post-Training: applying RL-based post-training to agents that perceive, plan, and act in real interfaces, with an emphasis on long-horizon decision-making, interactive feedback and reward design, and reliable agentic behavior.
  • RL-Empowered Reasoning in LLMs: developing efficient and scalable reinforcement learning methods to improve LLM reasoning performance (HeaPA). I am also interested in enabling generalizable System II reasoning in novel situations.

During my Ph.D., my thesis focused on exploring conceptualization (🐈, 🚗, 🕯️) and metaphysical reasoning (🪐), with an emphasis on robustness and reliable reasoning beyond pattern matching. I also actively worked on human behavior understanding and intention modeling with large foundation models in e-commerce (FolkScope, IntentionQA, MIND, 📜) and social media (MIKO), as well as on scientific knowledge exploration with large language models, studying their role in organizing, summarizing, and discovering scientific knowledge (arXiv2Table, Science Hierarchography, ClaimCheck).
