Mohsen Hejrati

Biography
Mohsen Hejrati works on building medical AI systems that are safe enough to be trusted with real patients. His current focus is on the hard problems that surface when AI agents move from demos into clinical settings: keeping models grounded in evidence rather than plausible-sounding output, knowing when a system should defer to a physician instead of acting, evaluating safety on the rare and high-stakes cases that averages hide, and earning the trust of clinicians who have to live with the consequences. He is interested in how these systems fit into existing clinical workflows without adding risk or burden. Earlier he was Senior Director of AI at Genentech, where he led AI teams and co-architected clinic-in-the-loop approaches to drug development. Before that he worked on machine learning at Google X. He is a repeat founder with three prior exits, and his research background is in machine learning.
