Janina Dill

Professorial Fellow
John G. Winant Associate Professor of U.S. Foreign Policy

Research Interests: U.S. military practices, International law, Laws of war/International humanitarian law, Just war theory, Changing character of war, Theories of international relations

I combine an interest in constructivist international relations and Just War theory with a quest to further our understanding of war’s evolving strategic reality, its moral and legal implications. My empirical work focuses in particular on U.S. military practices and the use of armed force as a tool in U.S. foreign policy making.

My current projects rely on a variety of methods, including interviews with victims of U.S. air strikes and military practitioners, experimental surveys, normative theorizing and legal exegesis to shed light on attitudes towards and the implications of “collateral damage”, i.e. civilian harm in war. I am also working on my second book, (commissioned by the Max-Planck Institute for Comparative Public Law and International Law and co-authored with Ziv Bohrer and Helen Duffy) which investigates the relationship of human rights law and international humanitarian law in the regulation of the conduct of hostilities.

Before joining Nuffield, I was an Assistant Professor at the Department of International Relations at the London School of Economics and Political Science. Alongside my current appointments, I hold a Research Fellowship at the Oxford Institute for Ethics, Law and Armed Conflict (ELAC) and I serve as a Senior Associate at Principia Advisory, a consultancy firm specialized in ethics.
