SALT LAKE CITY — Mohamed ElBaradei, Nobel Peace Prize laureate and former director of the International Atomic Energy Agency, will be the keynote speaker at the World Leaders Lecture Forum, sponsored by the University of Utah’s Tanner Humanities Center.

ElBaradei’s lecture, titled “The Challenge of Security in Our World,” will be held on Thursday, Sept. 13 at 3:30 p.m. in Kingsbury Hall, 1395 E. Presidents Circle. This event is free and open to the public, but tickets are required and may be obtained through the Kingsbury Hall box office by calling 801-581-7100.

ElBaradei will discuss how global inequity and insecurity challenge efforts for a durable, global peace. Based on his work in Iraq, Iran, and North Korea, he will speak about security in its broadest context, contending that national and international security requires more than large military arsenals.

ElBaradei’s talk will consider the role of nuclear weapons in global security and address the possibility of a nuclear weapons-free world with a sustainable global security system. He will argue that finding solutions to global conflict, poverty, hunger and disease are essential components of lasting security.
