Our Research

While Jens-Uwe Franck's research focus is on competition law, research projects regularly focus on cross-cutting issues and therefore also concern banking law and securities regulation as well as consumer protection law. His research is characterized by a comparative approach, a focus on the role of private and commercial law as an element of the European Single Market as well as an openness to interdisciplinary research, in particular to collaboration with economists.

Current research projects focus on the challenges to market regulation posed by the rise of digital platforms. Jens-Uwe Franck acts as project manager in the field of “Platform markets” within the CRC Transregio 224.
