Dr. Constantinos B. Papadias was born in Athens, Greece, in 1969. He is Professor at Athens Information Technology (AIT), as well as AIT's Doctoral Program Director. He received the Diploma of Electrical Engineering from the National Technical University of Athens (NTUA) in 1991 and the Doctorate degree in Signal Processing (highest honors) from the Ecole Nationale Supérieure des Télécommunications (ENST), Paris, France, in 1995. From 1992 to 1995, he was Teaching and Research Assistant at the Mobile Communications Department, Eurécom, France. In 1995, he joined the Information Systems Laboratory, Stanford University, Stanford, CA, USA, as Post-Doctoral Researcher, working in the Smart Antennas Research Group. In November 1997 he joined the Wireless Research Laboratory of Bell Labs, Lucent Technologies, Holmdel, NJ, USA, as Member of Technical Staff and was later promoted to Technical Manager. From 2004 to 2005 he was an adjunct Associate Professor at Columbia University. In 2006 he joined AIT in Athens Greece, as an Associate Professor and was promoted to Professor in 2007. From 2006-2011 he was also Adjunct Professor at Carnegie Mellon University's Information Networking Institute (INI).He has served on the steering board of the Wireless World Research Forum (WWRF) from 2002-2006. He was a Member of the IEEE Signal Processing for Communications Technical Committee from 2002-2008, acting as its Industrial Liaison, and is currently an Associate Editor of the IEEE Transactions on Wireless Communications and the Journal of Communications and Networks, published in Korea.His research interests range from baseband wireless communications and smart antenna systems to multi-user wireless networks to cognitive radio and multihop wireless sensor networks. He has published over 130 papers, 5 book chapters, one edited book, one research monograph ("MIMO Communication for Cellular Networks" by Springer, co-authored with H. Huang and S. Venkatesan) and has received over 3900 citations for his work. He has also made standards contributions (most notably as the co-inventor of the Space-Time Spreading (STS) technique that was adopted by the cdma2000 wireless standard for voice transmission) and holds 12 patents. He has participated in several European Commission research projects and is currently the Technical Manager of two FP7 Future & Emerging Technologies (FET) projects: "CROWN," in the area of cognitive radio networks and "HIATUS," in the area of interference alignment. From 2007-2009 he was a National Representative of Greece in the European Commission's FP7 program "IDEAS." His distinctions include the 2002 Bell Labs President's Award, a Bell Labs Teamwork Award, the 2003 IEEE Signal Processing Society's Young Author Best Paper Award and ESI's "most cited paper of the decade" citation in the area of wireless networks in 2006. The paper that he co-authored entitled "Is the PHY layer dead?" was rated as the 3rd most downloaded IEEE document on IEEE Xplore in April of 2011. He was listed as a "Highly Cited Greek Scientist" in http://www.highlycitedgreekscientists.org/ and was also recently appointed as an IEEE ComSoc Distinguished Lecturer for the period 2012-2013. Dr. Papadias is a Senior Member of the IEEE and a member of the Technical Chamber of Greece.
