She has conducted field investigations on children’s rights in Burma, Ghana, India, Indonesia, Morocco, Nepal, Sri Lanka, Uganda, and the United States. Based on her expertise on the issue of child soldiers, she has addressed the United Nations Security Council, testified before the US Senate Foreign Relations Committee, conducted trainings for US and African military officers, and testified as an expert in a Dutch war crimes trial. She has written several Human Rights Watch reports and her op-eds have appeared in the Washington Post, International Herald Tribune, The Guardian, and other major papers.
