The research at the chair of Professor Andreas L. Paulus focuses on matters of general public international law, in particular those pertaining to the doctrine of sources of law and their hybridization. This includes the analysis of the interrelations between different legal systems and the interplay between national and international courts. Research further concerns intellectual property rights, especially in their public international law and European law dimensions. In constitutional law, Paulus and his collaborators are also working on the freedom of speech and media regulation in the internet age.
