Research Scientist at Google DeepMind
London, England, United Kingdom
Summary
👤
Senior🎓
Top SchoolSamuel Holt is a Research Scientist at Google DeepMind focused on building LLM agents that learn and act via reinforcement learning, long-context memory, tool use, and inference-time search to enable scalable, assistant-like systems. He holds a PhD in machine learning from Cambridge and an MEng from Oxford, and his first-author publications include NeurIPS, ICLR, and ICML papers with multiple spotlights and a long oral. His work spans memory-augmented agents, unbounded code and content generation, and agents that optimize algorithms and simulators for scientific discovery. Samuel combines rigorous theoretical research with production-minded engineering—having built JAX RL pipelines, sim2real torque-control environments, and high-frequency trading systems earlier in his career. He likes pairing ideas with prototypes and evaluations that push toward self-improving, multi-agent workflows capable of producing large coherent artefacts (e.g., codebases or simulations). Based in London, he’s equally at home discussing planning, long-context generation, RL at inference, or automating parts of the scientific pipeline.
