Yuening Li
Staff Research Engineer · Google DeepMind
I am a Staff Research Engineer at Google DeepMind, where I contribute to post-training—spanning supervised fine-tuning (SFT) and large-scale reinforcement learning (RL)—for frontier Gemini models, including Gemini 4 Argon, Gemini 3.8 Flash, Gemini 3.8 Flash Cyber, and Gemini 3.5 Flash Cyber. My research focuses on long-horizon reasoning, autonomous coding agents, and frontier cybersecurity capabilities: training models that navigate complex, repository-scale codebases to discover, validate, and patch software vulnerabilities.
I received my Ph.D. in Computer Science from Texas A&M University (advised by Xia Hu) and my B.E. in Computer Science from Wuhan University.
Frontier Models & Post-Training
Google DeepMindContributed to SFT and RL post-training for Google DeepMind’s flagship 1M-context frontier reasoning models, optimizing long-horizon agentic execution, autonomous software engineering, and defensive cybersecurity capabilities.
