Alfonso Martinez (Zaragoza, 1973) has been a Ramón y Cajal Fellow since January 2012. He obtained his Engineering degree from the University of Zaragoza in 1997. In 1998-2003 he was a Systems Engineer at the European Space Agency, where his work on APSK modulation was instrumental in the definition of the new physical layer of DVB-S2. In 2003 to 2007 he was a doctoral candidate at TU Eindhoven, where he conducted research on optical communications. Between 2008 and 2011 he was a post-doctoral fellow with the Information-theoretic Learning Group at CWI in Amsterdam and the University of Cambridge. He is the Chair of the Spanish Chapter of the IEEE Information Society and serves as General Co-chair of the 2016 International Symposium on Information Theory, which will be held in Barcelona. His research interest lies in information theory, particularly on digital modulation and mismatched decoding; in this area he has coauthored a monograph on Bit-Interleaved Coded Modulation'. More broadly, he is intrigued by the connection between information theory and classical and quantum physics. He has written over 80 publications, including 20 journal papers.
