Find it at stage zero
Dr Julie Chen is Chief Medical Officer at Radence. When Marek and Aleksander filmed her in San Francisco in May 2024 she held the same title at Human Longevity — the company whose whole-body scan, genome and blood panel Marek had been through himself a few days earlier.
In her own description, she has previously served as Chief Medical Officer at companies such as Human Longevity and Vitagene. Her research — at the FDA, the NIH, the National Cancer Institute, USC and Mount Sinai — has shaped scientific advancement in precision medicine. She is a fellowship-trained integrative internal medicine physician who built corporate wellness programmes across Silicon Valley around a whole-systems approach to health. In 2023 she was named one of the Top 25 Women Leaders in Biotechnology by Healthcare Technology Report, and she sits in the Buck Institute’s President’s Circle.
She is on the Map at the Bridge of Prevention, and she is there for a particular reason: she is unusually clear-eyed about what early detection can and cannot promise. It cannot promise that nobody gets cancer. It can promise that something found at stage zero or one is a different problem from the same thing found later.
