Giorgos Papastergiou

Giorgos Papastergiou was born in Kavala (Greece) at 21/09/1982. He graduated from the Department of Electrical and Computer Engineering, Democritus University of Thrace (2005) and received his MSc degree in Informatics from Aristotle University of Thessaloniki, Greece and PhD degree from the Department of Electrical and Computer Engineering, Democritus University of Thrace, Greece, in 2007 and 2012, respectively. Giorgos has a long experience in delay/disruption tolerant networking, transport/network protocols engineering, experimental & theoretical analysis on performance evaluation, and testbed implementation. He has served as a visiting researcher at Jet Propulsion Laboratory for two months (April – May 2011). During this time, he was involved in the design and implementation of Delay Tolerant Payload Conditioning (DTPC) protocol, a transport protocol that has been lately adopted by CCSDS as a standard for future space communications. He has also served as a visiting researcher at Hellenic Aerospace Industry (HAI) for 18 months (Oct 2008 – April 2010), investigating issues related to space internetworking and delay tolerant networking. Giorgos has participated in many DTN-related projects funded by the European Space Agency (ESA) and the European FP7 Space program. Giorgos served his 9-month obligatory military duty in the Research and Informatics Corps of the Hellenic Army from March 2013 up to December 2013.
