Xavier Mestre received the MS and PhD in Electrical Engineering from the Technical University of Catalonia (UPC) in 1997 and 2002 respectively and the Licenciate Degree in Mathematics in 2011. During the pursuit of his PhD, he was recipient of a 1998-2001 PhD scholarship (granted by the Catalan Government) and was awarded the 2002 Rosina Ribalta second prize for the best doctoral thesis project within areas of Information Technologies and Communications by the Epson Iberica foundation.

From January 1998 to December 2002, he has been with UPC's Communications Signal Processing Group, where he has worked as a Research Assistant and has participated actively in the European-funded projects ACTS TSUNAMI-II, ACTS SUNBEAM, IST METRA, MEDEA+ UNILAN and IST-IMETRA. In January 2003 he joined the Telecommunications Technological Center of Catalonia (CTTC), where he currently holds a position as a Senior Research Associate in the area of Radio Communications. During this time, he has actively participated in the European projects MEDEA+ MARQUIS and IST COOPCOM, the networks of excellence IST NEWCOM and IST ACE, together with several contracts with the local industry.

He is IEEE Senior member and coordinator of the Radio Communications Research Area at CTTC. He has advised 2 PhD theses. He is associate editor of the IEEE Transactions on Signal Processing and associate co-editor of the special issue on Cooperative Communications in Wireless Networks at the EURASIP Journal on Wireless Communications and Networking.

His current research interests include: Array Processing, Cooperative Communications, Estimation Theory, Random Matrices and Multicarrier Modulations.
