In December 2024, I served as counsel and advocate for Sudan before the International Court of Justice (ICJ) in advisory proceedings on the obligations of States regarding climate change. My pleading begins at 1:07:30, which you can watch here.

Earlier, in February 2024, I represented Sudan at the ICJ in advisory proceedings on the legal consequences of Israel’s policies and practices in the Occupied Palestinian Territory. You can watch my pleading here, starting at 43:40.

At the International Criminal Court, I have served as ad hoc counsel for the defence, duty counsel for suspects, and legal adviser to witnesses in cases involving the situations in the Central African Republic, the Democratic Republic of the Congo, Ivory Coast, Kenya, and Uganda. See, for instance:

Acting as legal adviser to a witness in Prosecutor v. Mahamat Said Kani, Situation in the Central African Republic II, before Trial Chamber VI, 2024.

In 2000, I clerked for the Appeals Section of the Office of the Prosecutor which served both the International Criminal Tribunal for the Former Yugoslavia (ICTY) and the International Criminal Tribunal for Rwanda (ICTR). During this time, I was involved in the appellate proceedings for some of the first genocide cases in the history of international criminal justice: Prosecutor v. Akayesu, Prosecutor v. Kayishema and Ruzindana, and Prosecutor v. Musema. In 2002, I joined the team at the ICTY’s Office of the Prosecutor responsible for editing the tribunal’s digest of jurisprudence.

In Argentina, I focused on private law, criminal law, and labour law, with a particular interest in cases where these areas intersected with human rights law. Notably, I acted as advocate for the plaintiff in two cases concerning reparations for victims of enforced disappearance.
