During his work towards the Ph.D. degree at the VLSI Design Laboratory of the Electrical & Computer Engineering Department of the University of Patras, he contributed as a researcher in the following research projects funded by the European Commission (ESPRIT): A system supporting ASIC design and providing rapid turnaround prototyping (QUICKCHIPS), Hellenic design prototyping environment (HDPE I), A general hearing-aid processor (HEAR), Europractice Basic - Demonstration activity for Greek industries (MEDCHIP) and Asynchronous low-power methodology and implementation of an encryption/decryption system (AMIED).
The objectives of these projects were the enhancement of ASIC (application specific integrated circuits) design methodology (QUICKCHIPS, HDPE I), the design of a high-performance hearing-aid application specific integrated circuit (HEAR), the enhancement of training in microelectronics sector (MEDCHIP), and the implementation of the IDEA encryption/decryption method with reduced energy consumption (AMIED).
From November 2000 until April 2008 he was with the Research & Development Division of INTRACOM S.A. (INTRACOM TELECOM from January 2006), mainly working on as a senior engineer or project manager in several projects of the company.
From June 2013 until September 2014, he contributed to the Hellenic Open University project 'Educational content development for the new curriculums' funded by the Operational Programme for Education and Lifelong Learning (NSRF 2007-2013). In addition, from February 2014 until September 2014, he contributed to the National Technical University of Athens project Kallipos, regarding the development of Hellenic academic electronic books, funded by the same operational programme.
From November 2011 until October 2014 he contributed to the action Practical Training of Students at Technological Educational Institute (T.E.I.) of Western Greece, funded by the Operational Programme for Education and Lifelong Learning (NSRF 2007-2013).
From mid 2012 until mid 2015, he was a member of the reserach team for the project 'Innovative materials for nanocrystralline solar cells', co-ordinated by the University of Patras and funded within the context of action Thales of the Operational Programme for Education and Lifelong Learning (NSRF 2007-2013).
