ACELG's Research Programme Compound Constitutions in Europe is carried out by a research group of some 20 persons with internationally recognized scholars in the field of European law and European governance. The programme leaders Christina Eckes and Kati Cseres, are leading scholars, respectively in the fields of institutional law and governance of the EU and in European economic law and practice. The programme leaders are responsible for the programme as a whole in terms of its development, evaluation and for general guidance of the programme.

Part of ACELG's research is funded by external funding sources, including highly competitive research funding awarded by the Netherlands Organisation for Scientific Research, and by the University of Amsterdam as well as by government (including the Dutch Ministry of Justice and the European Parliament). In addition, the programme is embedded in local and international research networks (e.g. ACCESS EUROPE, Cleer, ReNEUAL).
