Ran Ilan Ber

Chief AI Officer at K Health

Tel Aviv District, Israel

About

With over 7 years of experience, I specialize in designing, building, and deploying AI systems that drive real-world impact. Most notably, I led the development of the first AI physician to outperform human doctors in managing real-life medical cases end to end — from initial patient complaints, through health record analysis and patient intake, to diagnosis and treatment. This work was recently published in Annals of Internal Medicine (2025).
