Rockstar🎓
Top SchoolPatrick Lewis is a London-based AI leader and researcher with a decade of experience building retrieval-augmented language models and agentic systems, currently serving as Senior Director of Agentic AI at Cohere. He completed a PhD split between FAIR and UCL, and has driven teams focused on retrieval, tool use, and agents after research roles at Meta/FAIR and industrial NLP engineering early in his career. His work sits at the intersection of information retrieval and large language models, emphasizing efficient, updatable knowledge representations for knowledge-intensive tasks like QA and fact checking. Known for translating deep research into production-ready modeling and tooling, he balances rigor from academic research with practical system-building at scale. An understated strength is his long-standing focus on making LLMs robust and maintainable via modular retrieval and tool integrations, not just performance gains.
