In addition to doctrinal research on the UN Security Council's Chapter VII powers and use of force norms in international law, his interviews with UN officials and state representatives in New York, South Sudan, Central African Republic and the DR Congo aim to clarify how different actors interpret their respective protection obligations toward civilians. Drawing on fieldwork in Rwanda, Sierra Leone and the DR Congo, he is also continuing his earlier research on international criminal tribunals with a focus on how international civil servants and government officials work with, despite, or against one another to shape domestic accountability processes. His book 'In the Court's Shadow: International Criminal Tribunals and Domestic Accountability' is forthcoming with Oxford University Press.

Patryk is excited to work with ACIL's renowned scholars, participate in events and workshops, and to develop collaborations for the future. Prior to joining ACIL, Patryk was a fellow at the Fletcher School of Law and Diplomacy and New York University School of Law. He holds a PhD in international law from the Graduate Institute of International and Development Studies in Geneva.

In February 2021, Patryk organised a very succesful panel discussion regarding the International Criminal Court and their decision to close the United Kingdom/Iraq preliminary examination. Over 200 people attended online and the recording can be watched here.
