​Dermot Groome is a former national and international war crimes prosecutor who is a professor of law at Penn State Dickinson Law. Groome’s research focuses on the emerging areas of human rights and international criminal law. With more than 11 years as a senior war crimes prosecutor for the United Nations’ International Criminal Tribunal for the former Yugoslavia, Groome is uniquely positioned to speak on topics relating to war crimes and genocide.

During his time working for the U.N., Groome investigated and drafted the first genocide indictment against a sitting head of state, Slobodan Milošević, and was the senior trial attorney for the Bosnia indictment. In total, he led the prosecution of five international criminal trials, including the case against Ratko Mladić, who was convicted of genocide for the murder of over 7,000 men and boys in Srebrenica in 1995. He also led eight large complex international investigations of senior military, political and police officials.

Groome has been working in the border region of Poland/Ukraine advising Ukrainian prosecutors investigating war crimes and crimes against humanity being committed by the Armed Forces of the Russian Federation.

In The Media

“It sends a clear message to other soldiers at different levels that they really need to think twice if they commit crimes, including Putin himself.”

“I think we could be looking at a new chapter in international criminal law. There’s a thing called universal jurisdiction, which empowers prosecutors around the world to bring these cases. But there have been practical difficulties before now in accessing evidence. We see satellite images, social media, phone videos that are available to these prosecutors at the click of the mouse.”
