I am a researcher at OpenAI, working on reasoning model post-training. Previously I worked for Salesforce AI Research on LLM Agent. I received my PhD and MS degrees from Carnegie Mellon University, focusing on RL and robotics. I finished my bachelor's degree with honor (President's Award) from Beihang University.

Research Interests

My long-term ambition is to develop AI agents capable of achieving and surpassing human-level performance in various daily tasks, ultimately freeing humans from repetitive work and enhancing productivity. Beyond the commonly recognized capabilities like reasoning and planning, I believe that continual self-evolution (in terms of training) and self-reflection (during deployment) are also essential traits of truly intelligent agents. This aligns with the core principles of reinforcement learning (RL), which I view as a guiding philosophical framework for thinking and studying AI agents.

My research aims to apply the foundational principles—not just the methods—of RL to large language model (LLM)-based agents, contributing to the promising future of AI Agent systems that that evolve, learn, and interact in ways that complement and enhance human capabilities. Currently, I am developing scalable approaches, such as utilizing synthetic data, to improve models' agentic abilities, and leveraging environmental feedback to better enable self-learning and reflection, as exemplified like the Software Engineering Agent.
