While the Stanford community may know him as former provost, professor emeritus, and co-director of SPRIE, William Miller is also chair and co-founder of Redwood City's Nanostellar, a start-up using innovative methods and new technologies to dramatically increase the efficiency of catalytic converters.

At an age when most others have retired (82), Miller is still looking for new ideas and opportunities for start-ups. Forbes.com's Elizabeth Corcoran profiled Dr. Miller's work at Nanostellar in Forbes: Turning Gold Dust Into Clean Air.

Forbes' Kym McNicholas interviewed Dr. Miller about Nanostellar's technology and how it is being used. See the Forbes: Video Interview with William Miller.
