After defending my PhD in 2012 at Universitat de Barcelona, I held several postdoctoral positions in Berlin, Münster and Barcelona, including a Marie Curie Fellowship at FU-Berlin and a research position as PI from the German Research Foundation at WWU-Münster. In 2019, I became Serra Húnter Lecturer at Universitat de Barcelona, and Associate Professor in 2024.
