Welcome to my homepage! Since Nov. 2014, I am a Principal Research Engineer at the Mathematical and Algorithmic Sciences Laboratory of Huawei Technologies, in Paris. My research encompasses the area of network optimization and machine learning. I enjoy using mathematical models to characterize performance limits and design algorithms to achieve these limits in practical systems. I am interested in the following topics:

NEWS
Our 2019 ICML paper, Cautious Regret Minimization: Online Optimization with Long-Term Budget Constraints
Our 2019 INFOCOM papers, (i) No Regret in Cloud Resources Reservation with Violation Guarantees , (ii) Large-Scale Network Utility Maximization: Countering Exponential Growth with Exponentiated Gradients , and (iii) Learning to Cache with No Regrets

NEWS that became past
Worked on the algorithmic foundations of the Hisilicon ASCEND 310 AI chip, which will be the brains of the next generation mobile phones.
Check our recent AI paper for Self-organized networks Model-Driven Artificial Intelligence for Online Network Optimization
I joined the IEEE Networking Letters editorial board
With G. Caire, G. Iosifidis, M. Tao, and D. Towsley, we organised the IEEE JSAC Special Issue on Caching for Communication Systems and Networks. Here is the link to the 33 accepted papers, while we also wrote a tutorial paper that explains why caching is a very important research topic for the future: The Role of Caching in Future Communication Systems and Networks

Check out our 2018 INFOCOM papers, (i) A Resource Allocation Framework for Network Slicing, (ii) Robust User Association for Ultra Dense Networks, and (iii) Traffic Engineering with Precomputed Pathbooks.
Check out our recent work on network slicing: The Algorithmic Aspects of Network Slicing which appeared in IEEE Communication Magazine 2017. Network slicing is a novel paradigm enabled by SDN and NFV. It has a key role to resolve main challenges in the upcoming 5G networks, like low latency communications. Check also the Huawei network slicing white paper.

With Prof. Elia and Spyropoulos, we co-organized a GdR meeting (CNRS) on the topic of ‘‘PHY-Aware Edge Caching in 5G: Convergence of Network and Information Theory in Cache-aided Wireless Networks’’ in 8th Dec 2017.
I gave a talk on ‘‘Network optimisation in the era of virtualisation’’ at Henry-Poincare institute in 30 Nov. 2017.
The 2nd workshop on Content Caching and Delivery in Wireless Networks (CCDWN) was held in WiOPT 2017.
Organised an ICC 2017 workshop on Advanced Caching in Wireless Networks.
Publicity chair for WiOPT 2017.
Invited talk in Tyrrhenian International Workshop on Digital Communications 2016 on ‘‘Caching for Wireless Networks’’.
Gave a tutorial session in ACM Sigmetrics 2016 on ‘‘Caching for Wireless Networks’’.
Co-organised the session ‘‘Queueing theory applications to future wireless networks’’, in the 2nd European Conference on Queueing Theory.
The 1st Content Caching and Delivery for Wireless Networks (CCDWN) was successfully organised in conjunction with ACM CoNEXT on Dec 1st 2015, in Heidelberg, Germany.
The 1st GdR MaDICS Workshop on Big Data for the 5G RAN was successfully organised on Nov 25, 2015, at Huawei Labs, Paris.
Biographical notes
Since Nov ’14, Georgios is a principal researcher at Huawei Technologies, Paris, France, leading the Network Control and Resource Allocation team. Previously, he worked two years at LIDS, MIT while before he held positions at CERTH- ITI, Greece ’08-’12 (researcher), University of Thessaly, Dept. ECE ’09-’11 (adjunct lecturer) and VTT, Finland, ‘07-‘08 (ERCIM Postdoc Fellow). He received his diploma in Electrical and Computer Engineering ’02 from Aristotle University of Thessaloniki, and his PhD degree in Wireless Networks ’06 from ECE dept. University of Patras, both in Greece. Two of his papers won the best paper award, in GLOBECOM 07’ and IFIP Wireless Days 09’ respectively. He serves as an associate editor for IEEE/ACM Trans. on Networking, IEEE Networking Letters, as a TPC member of INFOCOM, WiOPT, and Netsoft. He has organized several international workshops on the topics of caching, network slicing and machine learning techniques for communication systems, while he was the co-organizer and editor of the IEEE JSAC Special Issue on Caching for Communication Systems and Networks.
