High-quality legal research provides the basis for the Faculty’s operations. In addition to conducting research in traditional disciplines (such as private law, criminal and procedural law, international and EU law, and administrative law), the Faculty often collaborates with researchers from other fields in research on specific themes, such as globalisation, digitalisation and sustainable development.

The Faculty’s researchers are internationally recognised for their theoretical, critical and historical research approaches.

Several research units and projects, including the Erik Castrén Institute, the Finnish China Law Center and the Legal Tech Lab, also operate at or in connection with the Faculty.

The Faculty also offers doctoral education in law in the Doctoral Programme in Law, which is part of the University of Helsinki’s Doctoral School in Humanities and Social Sciences. Some 15–20 doctoral students graduate each year. Doctoral dissertations are mostly written in English.
