Visiting Professor at the Doha Institute for Graduate Studies and Senior Scientist at the Centre for Comparative Law of Charles University Faculty of Law.

His research interest includes constitutional and democratic theory, European law, comparative constitutional law, European decision-making processes, and judicialization of governance. He has also been involved in European private law projects ranging from torts to antitrust matters.

In his current research he looks into the constitutional origins of European integration and argues for a democratic constitutional interpretation that posits an existence of foundational constitutional principles that are expression of self-determination of Europeans and are superior to and independent of the mandate given to the EU by the Member States.
