Thomas Obel Hansen is a lecturer in the School of Law and a member of the Transitional Justice Institute since January 2016. Thomas obtained his LLM (2007) and PhD in Law (2010) from Aarhus University Law School in Denmark. Prior to joining the TJI, he worked as an assistant professor with the International Relations Programme at the United States International University in Nairobi, Kenya, where he taught Public International Law, Humanitarian Law and Human Rights, at the undergraduate and postgraduate levels. During his time in Kenya, Thomas also worked as an advisor and consultant for local and international organisations, in particular on assignments relating to transitional justice in the country and the region. Thomas’ research focuses on transitional and international justice, including doctrinal as well as socio-legal and international relations perspectives on such justice processes. Prior and ongoing research projects have examined issues relating to transitional justice theory; the politics and legitimacy of international justice; justifications for punishment of international crimes; the role of civil society in accountability processes; the ICC’s complementarity regime; the politics of international justice; and various doctrinal studies of international criminal law. He works on research grants to investigate accountability processes relating to alleged British war crimes in Iraq; examine legal processes in the UK for war crimes abroad; to establish the "Nairobi Principles on Accountability"; and to investigate the role of economic actors in transitional justice.
