He has been conducting research on medieval Japanese religions, with a focus on Shingon Buddhism and Shinto. His book, Rhétoriques de l’hérésie dans le Japon médiéval (2017), analyses the life and work of the Shingon monk known as Monkan (1278-1357) confronting primary sources with posthumous depictions of this gure as a “heretic.” He has also edited medieval manuscripts, and published several articles on medieval Buddhist paintings as well as digital humanities applied to authorship attribution of Japanese religious texts.
