Q&A: Chenyang Lu

In recent years, several disasters-including bridge failures-have illustrated that it's dangerous to take infrastructure for granted. Chenyang Lu, a professor at Washington University in St. Louis, is researching the technology of "cyberphysical systems," which combine wireless sensor networks and simulations. He spoke with Steven Cherry for IEEE Spectrum's "Techwise Conversations" podcast about how this technology could predict at least some failures.
