Engineering Sciences

Albert Guillén i Fàbregas is an ICREA Research Professor at Universitat Pompeu Fabra. He is also an Adjunct Researcher at the University of Cambridge. In 1999 he received both the Telecommunication Engineering Degree and the Electronics Engineering Degree from Universitat Politècnica de Catalunya and the Politecnico di Torino respectively, and the PhD in Communication Systems from École Polytechnique Fédérale de Lausanne in 2004. He has held appointments at the New Jersey Institute of Technology, Telecom Italia, European Space Agency, Institut Eurécom, University of South Australia and the University of Cambridge. He is a recepient of the Consolidator and Starting Grants of the European Research Council. He is a member of the Young Academy of Europe and a Senior Member of the IEEE. He is an Editor of the IEEE Transactions on Information Theory and the Foundations and Trends on Communications and Information Theory.


Research interests

The broad theme of his research is the mathematical foundations of communications, spanning the fields of Information Theory, Coding Theory, Communications Theory and Signal Processing. Its aim is to study the fundamental limits of reliable communication, along with schemes and processing algorithms that allow one to achieve them.
