Zhuyun Dai is a Staff Research Scientist at Google DeepMind with a decade of experience advancing LLMs, neural retrieval, and multimodal world models. Her work spans leadership on Gemini post-training (factuality and long-context capabilities), prior contributions to Bard factuality and multi-vector retrieval at Google Research, and a PhD from Carnegie Mellon focused on neural solutions for large-scale information retrieval. She combines deep research rigor with product-facing engineering, having collaborated with Ads and Search teams and led RL and reward-modeling efforts to improve factuality. Trained originally at Peking University, she brings a global perspective and rare end-to-end expertise from distributed retrieval systems to omni-modality generation.
