Summary
👤
Senior🎓
Top SchoolMehdi Fatemi is a Principal Research Scientist with 15 years of deep experience in reinforcement learning and sequential reasoning, currently driving research at Snorkel AI after leadership roles at Wand and Microsoft. He focuses on enabling “active thinking” in AI through value-based RL, with landmark contributions including concise reasoning, dead-end theory, dynamical causality, and state-of-the-art detoxification of large language models via far-sighted reasoning. A scientist by training (PhD from McMaster) and an accomplished practitioner, he has set a world record in Ms. Pac-Man using value-based methods and holds multiple US patents in RL. Equally at home in math and high-quality code, he regularly mentors and consults on computational programming and has had his work highlighted by outlets such as MIT News, Time, and BBC.
