I did my thesis within the Number Theory Research Group of Universitat Politècnica de Catalunya, under the supervision of Joan-C. Lario. After short research stays at the University of Cambridge, MIT and UCSD, I was a postdoc at the University of Bielefeld for 2,5 years. After this, I was a postdoc at the University of Duisburg-Essen for 2 years. I am heartfully thankful to the institutions and individuals that have welcomed me during all these years.
