Background

Albert Guillén i Fàbregas was born in Barcelona, Catalunya, Spain, in 1974. He received the Telecommunication Engineering Degree and the Electronics Engineering Degree from Universitat Politècnica de Catalunya, Barcelona, Catalunya, Spain, and the Politecnico di Torino, Torino, Italy, respectively, both in 1999, under the Double Degree Socrates-Erasmus Scholarship Program of the European Community, and the Ph.D. in Communication Systems from Ecole Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland, in 2004.

He is a Research Professor of the Institució Catalana de Recerca i Estudis Avançats (ICREA) hosted at the Department of Information and Communication Technologies, Universitat Pompeu Fabra, Barcelona, Spain, and a part-time Principal Research Associate at the Department of Engineering, University of Cambridge, United Kingdom, where he is also a Visiting Fellow of Trinity Hall. He is also a visitor at the Centre de Recerca Matemàtica.

From August 1998 to March 1999, he conducted his Final Research Project at the Center for Wireless Communications and Signal Processing Research, at the New Jersey Institute of Technology, Newark, NJ. He was with Telecom Italia Labs, Torino, Italy, from November 1999 to June 2000. From September 2000 to May 2001, he was with the European Space Agency (ESA), Noordwijk, The Netherlands. During his doctoral studies, from 2001 to 2004, he was a Research and Teaching assistant at the Mobile Communications Department, Institut Eurécom, Sophia-Antipolis, France. From June 2003 to July 2004 he was a visiting scholar at the Communications Theory Lab at EPFL. Since September 2004 until December 2006 he was a Research Fellow at the Institute for Telecommunications Research, University of South Australia, Mawson Lakes, Australia. From January 2007 unitl September 2011 he has been a Lecturer at the Signal Processing and Communications Laboratory, Department of Engineering, University of Cambridge, Cambridge, United Kingdom. He held visiting appointments at Ecole Nationale Supérieure des Télécommunications, Paris, France (June-July 2005 and June 2006), Universitat Pompeu Fabra, Barcelona, Spain (September 2008), at the Institute for Telecommunications Research, University of South Australia, Mawson Lakes, Australia (December 2008, June-July 2010) and Texas A&M Univeristy at Qatar (May 2010). His specific research interests are in the area of communication theory, information theory, coding theory, digital modulation and signal processing techniques, particularly with wireless terrestrial and satellite applications.

Dr. Guillén i Fàbregas received the Starting Grant from the European Research Council, the Young Authors Award of the 2004 European Signal Processing Conference EUSIPCO 2004, Vienna, Austria, the 2004 Nokia Best Doctoral Thesis Award in Mobile Internet and 3rd Generation Mobile Solutions from the Spanish Institution of Telecommunications Engineers, and a pre-doctoral Research Fellowship of the Spanish Ministry of Education to join ESA. He is an Associate Editor of the IEEE Transactions on Information Theory and an Editor of the Foundations and Trends in Communications and Information Theory, Now Publishers. He is also a Senior Member of IEEE (Information Theory and Communications Societies). He has been an Editor of the IEEE Transactions on Wireless Communications (2007-2011).
