Harrison is the co-founder and CEO of LangChain, an open-source framework designed to help developers build applications powered by large language models (LLMs). With a background in machine learning and deep learning systems, Harrison previously worked at Robust Intelligence and Google. He launched LangChain in 2022 to simplify the creation of intelligent agents and context-aware applications, rapidly becoming a leading figure in the emerging AI tooling ecosystem. His work focuses on enabling more powerful, composable, and production-ready LLM applications.

Hamel is a machine learning engineer with over 20 years of experience. He has worked with innovative companies such as Airbnb and GitHub, which included early LLM research used by OpenAI, for code understanding. He has also led and contributed to numerous popular open-source machine-learning tools. Hamel is currently an independent consultant helping companies build AI products.

Shreya Shankar is an experienced ML Engineer who is currently a PhD candidate in computer science at UC Berkeley, where she builds systems that help people use AI to work with data effectively. Her research focuses on developing practical tools and frameworks for building reliable ML systems, with recent groundbreaking work on LLM evaluation and data quality. She has published influential papers on evaluating and aligning LLM systems, including "Who Validates the Validators?" which explores how to systematically align LLM evaluations with human preferences.

Prior to her PhD, Shreya worked as an ML engineer in industry and completed her BS and MS in computer science at Stanford. Her work appears in top data management and HCI venues including SIGMOD, VLDB, and UIST. She is currently supported by the NDSEG Fellowship and has collaborated extensively with major tech companies and startups to deploy her research in production environments. Her recent projects like DocETL and SPADE demonstrate her ability to bridge theoretical frameworks with practical implementations that help developers build more reliable AI systems.
