What if we could recreate a community's population and health profile inside a computer model, and then use that model to completely redesign how we approach improving people's health? In her TEDx talk, Laura Landy describes a plan to do just that in communities across the country, and the surprising lessons her team are finding from their first efforts.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
