Professor Aptel contributed to establishing the United Nations (UN) international tribunals for the former Yugoslavia and for Rwanda, where she worked for 10 years in different legal and policy roles and drafted several of the first key judgments, including the first on genocide.

She has led and participated in various international efforts to foster criminal accountability for international crimes, gross human rights violations and terrorism, notably at the UN International Independent Investigation Commission in Lebanon, where she directed the legal services, and at the UN Office of Internal Oversight. She has served as the top senior legal advisor to successive UN High Commissioners for Human Rights, led the UN OHCHR global work on rule of law and democracy, and has advised on criminal accountability and judicial reform in several countries.

Professor Aptel has taught international law, focusing on international criminal law, international humanitarian law, human rights law, and transitional justice at the Fletcher School, Harvard, Pretoria University and Oxford University. She was awarded the 2010 Jennings Randolph Senior Fellowship by the United States Institute of Peace.
