From 2005 to 2007 he studied for his doctorate in mathematics at the Université Paris VI and the University of Vienna, with Joachim Schwermer as his supervisor.

[5] From October 2016 to October 2022 he led the international research programme "Special L-values and p-adic L-functions" and, from 2020 to 2023, the additional research project "Automorphic models and L-values for global algebras", both funded by the Austrian Science Fund.

[6] At the end of 2023, he was awarded another four-year research project, “New aspects of automorphic and smooth-automorphic forms,” by the Austrian Science Fund.
