Prof. Cronin was a post-doctoral research fellow at the Center for International Affairs at Harvard University. He has also taught at the University of Wisconsin-Madison. Cronin's specialties are in the fields of international law, international organizations, and human rights. He is currently writing a book on the manipulation of the international law of armed conflict by states whose military organizations are generally committed to following the laws and customs of war. The book focuses on how such states exploit their technological superiority by engaging in a form of warfare that is technically legal but recklessly disregards the basic principles underlying International Humanitarian Law.
