Biography
Athanasios (Thanos) Gkelias received his Diploma in Electrical and
Computer Engineering (major in Telecommunications) from the
Aristotle University of Thessaloniki, Greece, in 2000. He received his
MSc and PhD degrees in 2001 and 2006, respectively, both from the
Department of Electronic Engineering, King's College London. Currently,
he is a post-doctoral researcher at Imperial
College London working on Mobile-VCE Core 5 program. He is also the
project manager of the University Defense
Research Centre (UDRC) in Signal Processing at Imperial College
Sponsored by the UK Ministry of Defence (MoD).
In the past, he has participated in several ICT funded projects such as
MEMBRANE, e-SENSE and MIND. In 2006, he worked as an Associate Consultant for
Ovum's Telecoms Consulting Group in London. In the summer of 2008 he
was at Bell-Labs Research Centre,
Alcatel-Lucent, UK, working as a visiting researcher on wireless mesh
networks. During March-April 2007 he was a visiting researcher at
Athens Information Technology (AIT), Greece. His research interests lie
in the area of wireless ad-hoc, sensor and mesh networks, particularly in the
performance analysis and design of medium access control (MAC), QoS routing and
cross-layer issues.
