Ziad Obermeyer

Also known as زياد أوبرماير

Ziad Obermeyer is a physician and researcher at UC Berkeley whose work applies machine learning to health care. A 2019 study with Sendhil Mullainathan found that a widely used health algorithm underestimated the health needs of Black patients, and in 2021 he and colleagues released an Algorithmic Bias Playbook for health care. TIME named him to its 2023 TIME100 AI list, and he is a co-founder of Nightingale Open Science and Dandelion Health. In February 2024 he testified before the Senate Finance Committee about AI in health care. As of October 2026 he serves as Associate Dean for Innovation and Entrepreneurship at the UC Berkeley School of Public Health.
