(DPhil Oxon, MPhil Cantab)
Janina Dill is the John G. Winant Associate Professor of U.S. Foreign Policy at the Department of Politics and International Relations (DPIR) of the University of Oxford. She is also a Professorial Fellow at Nuffield College and Co-Director of the Oxford Institute for Ethics, Law, and Armed Conflict (ELAC).
Her research concerns international law and ethics in international relations, specifically in war. Janina Dill investigates how legal and moral imperatives interact with strategic thinking and technological developments to explain conduct in war and the development of armed conflict. She also works on IR theory, specifically constructivism and the intersection of explanatory IR theories with normative political theory.
Her first book, entitled Legitimate Targets? International Law, Social Construction and US Bombing, proposes a constructivist theory of international law and highlights tensions between a legal and a moral definition of a legitimate target of attack. It appeared with Cambridge University Press as part of the series Cambridge Studies in International Relations in 2015. The book was Runner-Up for the Birks Prize for Outstanding Legal Scholarship of the Society of Legal Scholars in 2016, and it has received an Honourable Mention by the Theory Section of the International Studies Association.
Her second book, entitled Law Applicable to Armed Conflict (co-authored with Ziv Bohrer and Helen Duffy), proposes a moral division of labour between human rights and humanitarian law and examines under what empirical circumstances each body of law should prevail over the other. It appeared in January 2020 with Cambridge University Press.

Law Applicable to Armed Conflict. Cambridge: Cambridge University Press (2020) - Ziv Bohrer, Janina Dill, Helen Dufy
Which law applies to armed conflict? This book investigates the applicability of international humanitarian law and international human rights law to armed conflict situations. The issue is examined by three scholars whose professional, theoretical, and methodological backgrounds and outlooks differ greatly. These multiple perspectives expose the political factors and intellectual styles that influence scholarly approaches and legal answers, and the unique trialogical format encourages its participants to decenter their perspectives. By focussing on the authors' divergence and disagreement, a richer understanding of the law applicable to armed conflict is achieved. The book, firstly, provides a detailed study of the law applicable to armed conflict situations. Secondly, it explores the regimes' interrelation and the legal techniques for their coordination and prevention of potential norm conflicts. Thirdly, the book moves beyond the positive analysis of the law and probes the normative principles that guide the interpretation, application and development of law.
Legitimate Targets? International Law, Social Construction and US Bombing. Cambridge Studies in International Relations, Cambridge: Cambridge University Press (2015)
Based on an innovative constructivist theory of international law the book investigates the effectiveness of international humanitarian law (IHL) in regulating the conduct of hostilities. A comprehensive exegesis of the law defining a legitimate target of attack reveals an unacknowledged controversy among legal and military professionals about the logic according to which belligerents ought to balance humanitarian and military imperatives: the logics of sufficiency or efficiency. Although IHL prescribes the former, increased recourse to IL in US air warfare is constitutive of a legitimate target in accordance with the logic of efficiency. The logic of sufficiency is morally less problematic. Yet, neither logic satisfies contemporary expectations of effective IHL or legitimate warfare. Those expectations demand that hostilities follow a logic of liability, which proves impracticable. The book proposes changes to IHL, but concludes that according to widely shared normative beliefs on the 21st century battlefield there are no truly legitimate targets.
