After studying public law at Jean Monnet University in Saint-Étienne, Thibaut chose to dedicate his research to fundamental rights and freedoms, focusing particularly on the interplay of the various mechanisms designed to ensure their protection.

In his doctoral thesis, entitled "Priority Preliminary Ruling on Constitutionality and Review of Conventionality," which was awarded the Constitutional Council Prize in 2021, Thibaut tackles head-on the complex issues related to conflicts of norms and methods, and the dialogue between judges who uphold rights and freedoms.

And the expertise Thibaut has developed is not solely academic.
During his doctoral studies, Thibaut served for four years as a legal secretary at the European Court of Human Rights. In this capacity, he participated in all stages of the Strasbourg Court's litigation: screening applications, drafting single-judge reports, examining requests for interim measures, and drafting committee and chamber judgments.

Thibaut, a lecturer at Paris 1 Panthéon-Sorbonne University for three years, passed the competitive examination for professorship in public law in 2025 and is currently a Professor at Evry-Paris-Saclay University.

Alongside his teaching and research activities, Thibaut regularly handles priority preliminary rulings on constitutionality and applications before the European Court of Human Rights. Author of numerous publications, notably in the Quarterly Review of Human Rights, Thibaut is currently preparing a handbook on European litigation law.

Thibaut advises on all matters relating to fundamental rights and freedoms.
