Josh Meier

Josh Meier is Co-Founder and CEO of Chai Discovery, a company applying artificial intelligence to drug discovery. His interest in combining biology and computing began in high school, where he conducted stem cell research, and continued at Harvard University, where he studied computer science and chemistry. He joined OpenAI in 2018 before moving to Meta’s AI research lab, where he helped pioneer the use of language models to understand proteins, revealing how AI could learn patterns in biology much as it learns patterns in human language. He later served as Chief AI Officer at biotechnology company Absci. In 2024, Josh co-founded Chai, bringing together years of research at the intersection of biology and computing to pursue a new approach to developing medicines.
