I took my Ph.D. in Mathematics in 2020 at Scuola Scuola Normale Superiore of Pisa (Italy). From Feb. 2020 to Jan. 2022 I was PostDoc at University of Basel (Switzerland). From Feb. 2022 to Aug. 2024 I was PostDoc at Scuola Internazionale Superiore di Studi Avanzati of Trieste (Italy). Since Sep. 2024 I am a fixed-term Researcher at University of Padova (Italy).
