When he's in Africa, human rights activist John Prendergast often hangs out with George Clooney, Don Cheadle, and Ryan Gosling, not to mention African rebels and officials alike.

On Friday, he's going to be hanging out with College of Charleston students. The Department of Political Science is hosting Prendergast as this year's Convocation of Majors speaker where he will present "10 Building Blocks for Making a Difference: In Africa and in Your Own Neighborhood."

The event, which is free and open to the public, begins at 3 p.m. in Physician's Memorial Auditorium.

Prendergast is a human rights activist and best-selling author who has worked for peace in Africa for more than 25 years. He is the co-founder of the Enough Project, an initiative to end genocide and crimes against humanity affiliated with the Center for American Progress. With the Enough Project, Prendergast has traveled to Africa with celebrities like George Clooney and NBA star Tracy McGrady, as well with NBC's Dateline, ABC's Nightline, The PBS NewsHour and CNN's Inside Africa.

Prendergast has worked for the Clinton White House, the State Department, two members of Congress, the National Intelligence Council, UNICEF, Human Rights Watch, the International Crisis Group, and the U.S. Institute of Peace.
