Hengyi Cai

I am a Research Scientist at Baidu Inc., where I develop the company’s in‑house LLM infrastructure and large‑scale query understanding systems that power Baidu Search. My research spans text generation, question answering, and retrieval‑augmented language models, with publications in ACL, EMNLP, KDD, NeurIPS, and SIGIR. I earned my Ph.D. from the Institute of Computing Technology, Chinese Academy of Sciences in 2021 (Outstanding Graduate). I serve on program committees for leading conferences including ACL, EMNLP, KDD, NeurIPS, and SIGIR.
