Ryngaert's research examines the law of jurisdiction, with particular attention on pathways that lead to sustainability, institutions for open societies, and security in open societies (SOS). He authored a book entitled Jurisdiction in International Law in 2015 about the areas of law where jurisdiction is most contentious: criminal, antitrust, securities, discovery, and international humanitarian and human rights law. Michael Waibel is of the view that the book "holds out a utopian benchmark where States exercise jurisdiction solely in the interest of furthering global welfare, based on specific jurisdictional rules for each field of law." He further describes the book to be a "comprehensive analysis" of the admissible geographical reach of State legislative power, which highlights "transatlantic jurisdictional wrangles" that are limited to US and European State practice. His work also examines the position of non-state actors as law-makers and law-takers in the context of international law. He addresses questions about whether these different positions can or should be separated from each other. In 2015, Ryngaert co-edited the book, Non-State Actors in International Law, with Math Noortmann. The book highlights that the position of non-state actors in international law changes with the functional and theoretical perspectives of the observer. Marcos D Kotlik described the book as being focused on "constraints of state-centric approaches in accurately depicting the role and status of non-state actors in the international arena." More recently, Ryngaert authored a book, Selfless Intervention: Exercising Jurisdiction in the Common Interest, and explored several concepts of international law, such as jurisdiction, sovereignty, and territoriality. He investigated the ways in which purpose of the law of jurisdiction undergoes a shift from protecting national interests to furthering international concerns. While discussing criminal law as a mechanism to hold corporations to account, Ryngaert performed a case-study on the Dutch criminal law system and argued that criminal liability can be based on violations of a corporate duty of care violation, on the other hand jurisdiction can be grounded on the principles of territoriality, nationality, and universality. He also published a paper on "Embassy Bank Accounts and State Immunity from Execution" with an intention to introduce an approach which has the capability to bring a balance between the interests of states and creditors while doing justice to the creditor's right of access to a court. He discussed how the United States is continuously weaponizing economic sanctions to accelerate its foreign policy agenda. Having discussed that, he highlighted the inauspicious impacts of secondary sanctions, and the role that third states and the EU are playing to counter these sanctions through various non-judicial mechanisms, such as blocking statutes, special purpose vehicles to circumvent the reach of sanctions, or even countermeasures. Moreover, Ryngaert has focused his research to identify the jurisdictional opportunities and pitfalls of criminal (public law) and civil/tort (private law) litigation against PMCs in domestic courts.
