Reijer’s research focusses mainly on constitutional democracy, constitutional change and comparative constitutionalism. He is also increasingly more interested in digitalization and sustainability. Reijer is an advocate of interdisciplinary and historical approaches to constitutional issues, as such approaches allow us to better understand how constitutional norms actually emerge, operate and eventually decay and how they shape the real-world.
Reijer published in, amongst other peer-reviewed journals, the Cambridge Journal of Comparative and International Law, the Theory and Practice of Legislation, the Dutch Journal of Constitutional Law and in Buffalo Law Review. He presented papers in places like Durham, Milan, Austin, New Haven (Yale University) and on Procida, Italy.
