BIO

Actively engaged over the last 10 years in the preparation and technical management of a large number of market-driven innovative EU (FP7 and H2020) and industrial projects, in the broader area of networking and telecommunications. These include 12 large (3 and 4 year) research, innovation and development projects on access networks, high capacity core networks and novel transmission and switching technologies. All projects are/were in collaboration with major European industrial players including large operators (Telefonica, FT-Orange Labs and BT) and system vendors (Alcatel-Lucent, Ericsson, ADVA, Finisar).

Personal duties and responsibilities include:

  • Technical coordination of multi-disciplinary teams from industry and academia, as part of work package leading and (lately) technical leading role.
  • Technology solutions identification and evaluation related mainly (and not limited) to: network design aspects, control protocol solutions, network performance analysis and optimization, transmission performance evaluation and techno-economic analysis.

ACADEMIC RESEARCH
Research and development

Athens Information Technology (AIT)
Networks and Optical Communications Group
Researcher
Photonic Networks Research Lab, University of Essex, UK

  • Acted as the main investigator and developer for the project OPSnet demonstrating the first asynchronous optical packet switched node functions at a bit rate of 40Gb/s with real time header detection and processing.
  • Worked closely with BT, initially in project OPSnet and later in the study and development of the first national research optical network infrastructure among the universities of Essex, Cambridge and UCL
  • Established new collaborations with CIP (now part of Huawei) and major UK research institutes (Cambridge University, UCL, Imperial and St Andrews University), leading to new project initiatives.
  • Was responsible for the upgrade of the Photonics Network Research laboratory infrastructure, being in close contact with advanced test equipment providers and performing the testing and evaluation of the equipment.
