I left clinical medicine after three years because the 1 to 1 engagement with patients, as gratifying as it is, was limiting my impact. I seek scalable approaches to improving health. As our healthcare systems are strained while our expectations of what "good outcomes" mean change, we need to rethink the way we provide health services. Fortunately, the internet, artificial intelligence, and behavioural science are giving rise to fantastic opportunities to solve the problems of providing high-value health services.
