His recent work investigates social philosophy through the lens of “commoning”, and he leads two major funded projects: an in-depth study of Cicero’s Tusculanae Disputationes as a specifically Roman philosophical project (DFG, 2020-), and a new project on happiness as the first principle of ethics in Albertus Magnus (Fritz Thyssen Foundation, 2023-).
