Dr. Hood, who is 84, is at the forefront of a movement to overhaul healthcare. Technically speaking, he is the cofounder of the Institute of Systems Biology (ISB), a biomedical research group, and the CEO of Phenome Health, a health-technology nonprofit. But what he really is, above all else, is a man with a mission. Hood spends his days on calls with scientists, senators, philanthropists, and tech giants, trying to transform healthcare systems across the globe by making them better at preventing diseases, rather than reacting to them. That way, we can all live a little longer.
