Rebecca Tinsley is a director of Waging Peace, an organization that campaigns against genocide and systematic human rights abuses. Formerly with the BBC, as a journalist and author she has traveled in Rwanda, Bosnia and Darfur, writing for publications such as the New Statesman, Times, Independent and Telegraph. She has published two novels. Rebecca Tinsley has stood twice for parliament and was national chair of the Union of Liberal Students. She is on the Human Rights Watch London committee, is a trustee of the Carter Centre UK and the Bosnian Support Fund, and is a founder and director of the Rwanda Girls School.

Waging Peace puts a particular focus on Africa and on atrocities overlooked by the international community where minorities have been persecuted on racial or religious grounds. The organizations current priority is Darfur, but Waging Peace works to secure the full implementation and enforcement of international human rights treaties wherever it is active and produces regular, high-level and in-depth research reports which support the call for urgent, effective and measurable action from the international community.
