Currently on CNRS delegation at CEVIPOF/Sciences Po (2025–26), his research addresses the theme of the “crisis of democracies.” His project seeks to analyze, from a socio-historical perspective, the enduring recurrence of this theoretical concern throughout the 20th and 21st centuries, and its various forms of expression across three critical moments: the interwar period, the 1970s–1980s, and the 2010s–2020s.
