Professor Renzo works primarily in legal and political philosophy. His main research interests are in the following four areas:

1. Political authority, with a focus on the questions of what justifies the right of states to create and enforce moral obligations, as well as to claim control over certain territories and their natural resources; the question of the relationship between political authority and practical reasoning; the questions of justified disobedience and conscientious objection. 
2. Just war, with a focus on the question of what justifies lability to be killed in war; the question of whether there can be a duty to obey an order to fight an unjust war; the question of the justification of humanitarian intervention and of wars fought in order to protect political goods. 
3. Philosophy of the criminal law, with a focus on the question of the philosophical foundations of self-defence and complicity; the question of how we should understand the authority of international criminal law; the question of the justification and the limits of criminalization.
4. Human Rights, with a focus on the questions of how we should conceptualize human rights and of what justifies their existence.

Professor Renzo is happy to supervise students working in any of these areas.
