I am a senior researcher at Tencent AI Lab working on math reasoning with LLM and RLAIF, especially through search + RL approaches. I have been working on NLP fields since 2010. I earned my Ph.D. degree from the Computer Science Department at the University of Rochester (UofR), advised by Professor Daniel Gildea. I earned my master degree from the Institute of Computing Technology, Chinese Academy of Science (ICT/CAS), advised by Dr. Qun Liu.
