I am a Romanian-American political philosopher. I joined King's College London in 2015, where I am an Associate Professor (Reader) in Politics, Philosophy, and Economics in the Department of Political Economy. I have served as the first director of the new PPE program from 2015-2018.

During April-May 2022 I was a visiting scholar at the University of Oslo in the Department of Philosophy with the DynamiTE project. During the academic year 2022-2023 I am a visiting fellow at the Center for Ethics and Public Affairs at Tulane University. 

I have broad interests in questions at the intersection of politics, philosophy, and economics, and in the philosophy of law, especially international law.  My recent publications cover the nature of rights and how states institutionalize them, constitutional theory and the rule of law, the character and scope of international law and institutions, and public policy

My latest book, Law Beyond the State: Dynamic Coordination, State Consent and Binding International Law (OUP 2021) is the winner of the Best Book Award  at the International Studies' Association International Law section.

I am one of the editors of the new Oxford University Press Philosophy, Politics and Economics book series.
