Biography

Thanasis Korakis was born on December 4, 1972 in Ioannina, Greece. He obtained the Bachelor and the M.S. degree in Informatics and Telecommunications from the University of Athens, Greece, in 1994 and 1997 respectively. He obtained the Ph.D. degree in Computer and Communication Engineering from the University of Thessaly, Greece in 2005, under the supervision of Professor Leandros Tassiulas. In the summer of 2004 he was a visiting researcher at the Computer Science & Engineering Department at the University of California, Riverside. From 2005 to 2006 he was a Research Scientist associated with the New York State Center for Advanced Technologies in Telecommunications (CATT).

Dr. Korakis is currently a Research Assistant Professor in the Electrical and Computer Engineering Department of Polytechnic Institute of NYU. He is also affiliated with CATT at NYU Polytechnic School of Engineering. His research interests are in the field of wireless networks with emphasis on access layer protocols, cooperative networks, directional antennas, quality of service provisioning and network management. He leads the Wireless Implementation Testbed Laboratory (Witest Lab) of the Department of Electrical and Computer Engineering at Polytechnic Institute of NYU.

Dr. Korakis follows the standardization activities for 802.11 and 802.16 very closely. Since March 2007, he is a voting member of the IEEE 802.16 standardization group as well as a regular participant in the meetings held. He is the Finance Chair for ITW 2009. He served as a Publication Chair for WiOpt 2007 and as a member of the Technical Program Committee for ICC 2008, WCNC 2008 and SECON 2008. He was awarded the Ericsson Award of Excellence in Telecommunications for work related to his Ph.D. in 2006.
