Marie Gren is a Full Professor of Public Law at the Panthéon-Sorbonne University. She specializes in comparative constitutional law and legal theory. She has taught in various fields of public law in French and English. She has been a visiting Researcher at the University of Tel-Aviv (2013) and Columbia University (2014) and an Erasmus Scholar at the Jagiellonian University in Krakow (2022). She has worked as a Foreign Clerk at the Israeli Supreme Court and as a Public Law Advisor at the French Cour de cassation. She speaks fluent French, Polish, and English and also has a good command of Hebrew and Russian. Her research is focused mainly on constitutional transformations and constitutional education. Her PhD research (published as a book in 2019) dealt with the shift of constitutional paradigms akin to the scientific revolutions described by Thomas Kuhn. The case study of this theoretical analysis was the progressive transformation of French, British, and Israeli systems towards a greater preeminence of constitutional norms, under the joint efforts of judges and legal scholars. She is currently working on a general overview of Legal Traditions, on the evolution of constitutional education in Universities and schools, and on a project of rewriting of the French Constitution by foreign scholars.
