Fité Naya, Francesc

I am a Ramón y Cajal research fellow at Universitat de Barcelona. I obtained my PhD at Universitat Politècnica de Catalunya and in between I have enjoyed postdoctoral positions at Bielefeld Universität, Duisburg Essen Universität, UPC, the Instititute for Advanced Study (Princeton), and at the Massachusetts Institute of Technology. I am interested in the arithmetic of abelian varieties. In collaboration with Kiran Kedlaya, Victor Rotger, and Andrew Sutherland, we have obtained a classification theorem for Sato-Tate groups of abelian varieties of dimension up to 3.
