Youk Chhang is the Executive Director of the Documentation Center of Cambodia, a project begun by the Cambodian Genocide Center at Yale University. The Center, operated entirely by Cambodians, gathers evidence of human rights violations by members of the Pol Pot regime.

The Center's aims are to provide the public with a better understanding of the Pol Pot regime, and to those who might wish to pursue legal redress for crimes which might have been perpetrated under the Democratic Kampuchea, and to prevent the return of the Killing Fields to Cambodia through legal and peaceful means.

Prior to working with the DC-Cam, Chhang was appointed by the United Nations to be part of the election monitoring force in Cambodia. He also served as community relations advisor to the Dallas, Texas Police Department.
