A former Human Rights Watch researcher, Vandenberg spearheaded investigations into human rights violations in the Russian Federation, Bosnia & Herzegovina, Uzbekistan, Kosovo, Israel, and Ukraine. She is the author of two Human Rights Watch reports, “Hopes Betrayed: Trafficking of Women and Girls to Post-Conflict Bosnia & Herzegovina for Forced Prostitution,” and “Kosovo: Rape as a Weapon of ‘Ethnic Cleansing.’”
