Research areas

Professor Lang's research focuses on the intersection of politics, law and ethics at the global level. These themes are explored through the lens of global constitutionalism, human rights, international responsibility, and the just war tradition. Within these different areas, Professor Lang has focused on issues such as global constituent power, international organizations, international law, and military intervention. His work has drawn on 20th century figures such as Hans Morgenthau, Hannah Arendt, and Judith Shklar, and historical figures such as Aristotle and Hugo Grotius.

Professor Lang's previous work has addressed international political theory, with a particular focus on questions of agency, responsibility and punishment. These theoretical questions have been explored through various global practices such as humanitarian intervention, international security strategy, war crimes, and counter terrorism policy.
