I am a Staff Engineer at Google, focusing on effective and efficient post-training methods and developing intelligent agent frameworks capable of performing complex tasks such as reasoning over complex questions (DeepResearch) and generating high-quality documents and slices (Long Horizon RL). I was a Principal Researcher from Tencent AI Lab, working on LLM post-training and RL over reasoning and agentic tasks. I won the Best Long Paper Award (1 out of 1250 long-paper submissions) at NAACL 2021. I hold a Ph.D. in Computer Science from the University of Rochester (UofR), where I was advised by Professor Daniel Gildea, and a master’s degree from the Institute of Computing Technology, Chinese Academy of Sciences (ICT/CAS), under the mentorship of Dr. Qun Liu.
