Following 35 years on the faculty of Columbia University in New York, more than half of that time as Chair of the Department of Astronomy and Astrophysics, Dr. Helfand developed a deep understanding of the problems of traditional universities. Seizing an opportunity to redesign higher education from scratch, he has served as a Founding Tutor and, since 2008, as President and Vice Chancellor of Quest University Canada. He is also President of the American Astronomical Society, the professional society for astronomers, astrophysicists, planetary scientists and solar physicists in North America.

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)
