Loung started her activism work in 1993 when she became the Community Educator for a domestic shelter in Maine. Since then, she has worked on various campaigns to end violence against women, to end the use of child soldiers, and to eradicate landmines globally.

In 1995, Loung made her first trip back to Cambodia—and has returned on over forty trips—devoting herself to helping her native land heal from the traumas of war. In 2013, Loung expanded her activism reach to screenplay writing and was one of the writers for Girl Rising, a groundbreaking film directed by Academy Award nominee Richard Robbins.

For her work, the World Economic Forum selected Loung as one of the “100 Global Youth Leaders of Tomorrow.”

Among the publications, television and radio shows she has been featured on are The New York Times, Washington Post, USA Today, People Magazine, CNN, Fresh Air with Terry Gross, and The Today Show.

In addition, she has been the subject of documentary films broadcast by Nightline, German ARTE, and Japanese NHK. Loung has given hundreds of keynote addresses at numerous forums in the U.S. and internationally, including at, Stanford University, Dartmouth College, Philips Academy, Facing History and Ourselves, Women in the World Summit, the U.S. Coast Guard Academy and Mexico 1 Million Youth Summit.
