Before this he has worked in Area 11 (the research area) of AT&T Bell Laboratories, Holmdel, NJ, as a member of technical staff. He has performed and led blue-sky and applied research to turn photonics concepts into applied solutions for telecoms, datacoms and sensing. He has initiated and successfully lead more than 23 large, collaborative, cross-European, research projects. He has authored/co-authored around 500 articles in peer reviewed international journals and conference presentations and holds several international patents. He has also served in posts as Panel Member of the European Research Council (ERC), member of conference program committees (currently for the European Conference in Photonic Communications (ECOC)), has been an active member of the Board of Stakeholders of the Photonics 21 Association and others. Most happily he has been the advisor of 35 young engineers and physicists that have completed their research towards their PhDs and a further 11 are currently at various stages of the completion of their research at PCRL. They have attracted several distinctions at a national and international level. Seven of the alumni of PCRL are now faculty academics in Greek universities and have developed independent research lines while others have attained high profile posts in industry and two of them have spawned 2 start-ups.
