I did my PhD Degree  at the Università degli Studi di Milano joint with the Universidad Complutense de Madrid, under the direction Prof. Enrique Arrondo Esteban and Prof. Antonio Lanteri.

In 2012 I was a PostDoc Universidade Estadual de Campinas in which I became an Associate professor in June 2014.

Since september 2019, I am an Associate professor at the Universitat de Barcelona.
