Serra, Oriol

I graduated in Mathematics at the Universitat de Barcelona (1983) and obtained a PhD in Mathematical Sciences at Universitat Politècnica de Catalunya (1988). I am full professor at the department of mathematics of UPC since 1999.

I was visiting fellow at University of California, Santa Cruz (1994/95), ENS Télécommunications Paris (2000), Rényi Institute Budapest (2001), Charles University Prague (2005), Institute de Mathématiques de Bordeaux (2012).

 I have served as chair of the department of mathematics (2011-2017), vicedean of research of the School of Mathematics at UPC (2007-2011), member of the Executive Committee of the Barcelona Graduate School of Mathematics (2012-2015) and member of the Counclil of the European Mathematical Society (2012-2017) among other duties.
