Welcome

Chris Vagionas is a PostDoctoral Researcher at WinPhos Research Group , (link) at the Arisotle University of Thessaloniki (AUTh).

As a postodoctoral researcher, Dr. C. Vagionas has been awarded the postdoc research grant of ELIDEK to work on Optical Content Addressable Memories for Ultra fast Address Look-UP. The project CAM-UP (http://www.cam-up.gr/) has received funding from the Hellenic Foundation for Research and Innovation (HFRI) and the General Secretariat for Research and Technology (GSRT), through the CAM-UP project under grant agreement No 230.

Chris received the Diploma of Electrical and Computer Engineering from the respective Department (2008), and the M.Sc. and Ph.D degree from the Dep. of Informatics (2011 and 2017 respectively) of the Aristotle University of Thessaloniki in Greece. He was a Marie-Curie fellow in FP7 MC-IAPP project COMANDER , and has has also served as a Research Associate at CERTH (Center for Research and Technology Hellas) for approximately four years.

His Ph.D. research has been focused on developing the necessary photonic technology framework for enabling optical memories that support wavelength encoding schemes and caching functionalities using light instead of electroncs, achieving so far to implement the core building blocks, through the RAMPLAS EU ICT research project envisioning integrated Optical RAM chips for High-Speed Applications in Computing and Communications.

He has been also been working towards Fiber Wireless networks for 5G and beyond, while he has been involved in many european and national research projects.

Additionally, he has been collaborating as a visiting researcher at Phoenix Software at Enshcede, in the Netherlands, towards developing efficient and validated time domain numerical modeling techniques of Semiconductor Optical Amplifiers and SOA-based Photonic Integrated Circuits (book chapter published).

Dr. Vagionas has authored or co-authored:
- >20 journal publications at IEEE Journals, including J. of Lightwave Technology, J. of Quantum Electronics, Photonics Journal and Photonics Technology Letters,
- >40 international conference proceedings
- 2 book chapter and
- 2 national proceedings
while regularly serves as a reviewer for various publishers, such as IEEE Photonics Society, OSA, Applied Sciences, Elsevier, Springer, etc.

Chris is a recipient of the IEEE Photonics Society Graduate Student Fellowship 2016 . In addtion, he was awarded the Newport Travel Grant awarded by OSA at Conf. Lasers and ElectroOptics (CLEO) in 2012 at San Jose, CA, USA, a SPIE student travel grant at the Photonics Europe Conference in 2014 at Brussels, Belgium and a Best Paper Award in 2011 at a national conference (EUREKA) in Kastoria, Greece.

He obtained his M.Sc. in "Networks, Communications and Systems Architecture" from the Department of Informatics of AUTh in Feb. 2011, ranking 1st in the MSc and honoured twice with a Scholarship/Best M.Sc. student award for his excellence during his postgraduate studies. His thesis on "A Semiconductor Optical Amplifier (SOA) model based on the Transfer Matrix Method (TMM)" resulted in a respective publication at 5th Eureka Panhellenic Conference on Infromatics, Applications and Related Technologies at Kastoria in 2011, work that was greed with the Best Paper Award.

During his undergraduate studies as an Electrical and Computer Engineer in the Faculty of Engineering at AUTh, he specialized in Telecommunications and obtained his diploma in July 2008. His thesis he focused on "Numerical modelling of the electromagnetic wave propagation in urban areas based on parabolic equation approximations".

Finally he served as a volunteer network adinistrator at the University's Network Operation Center for two years, receiving practical training on protocols of the OSI model.

He is an IEEE/IEEE Photonics Society student member, member of the Technical Chamber of Greece and member of the Electrical & Computer Engineer Association of Northern Greece
