Reeves started studying politics and human rights in Sudan in 1998.[1] He testified several times before the United States Congress, has lectured widely in academic settings, and has served as a consultant to a number of human rights and humanitarian organizations operating in Sudan. Working independently, he has written on several aspects of Sudan's recent history, in particular the Darfur genocide, and the role of the Sudanese and Chinese governments in perpetuating it. He was described as "a fierce critic" of former American President Barack Obama's policy of reconciliation with Sudan.[1]
