CV
I did my thesis within the Number Theory Research Group of Universitat Politècnica de Catalunya (UPC), under the supervision of JoanC. Lario. After short research stays at the University of Cambridge, MIT and UCSD, I was a postdoc at the University of Bielefeld, the University of DuisburgEssen, and UPC/BGSmath. I was a member at the Institute for Advanced Study for the academic year 201819 and then a research scientist at MIT from 2019 until 2021. I am heartfully thankful to the institutions and individuals that have welcomed me during all these years.
