Dr. Georgia Sakellari

I am an Associate Professor of Networked Systems at University of Greenwich and Deputy Head of the ISEC research group.

Previously, I was a Senior Lecturer in Distributed Systems and Networking at Middlesex University and before that I was a Lecturer at the University of East London and a Post-Doctoral Research Associate at Imperial College London.

I received my Ph.D. in Computer Networks from Imperial College in 2009, after a MSc (MBA) in Techno-Economic Systems and a MEng in Electrical and Computer Engineering from N.T.U.Athens.


Research Projects


RESCUER: First Responder Centered Support Toolkit for Operating in Adverse and Infrastructure-less Environments

RESCUER develops a technology toolkit for the next-generation of First Responders, enhancing their operational capacity and safety, specifically in adverse conditions, both environmental and infrastructure-wise. It will deliver sense augmentation through enhanced sensorial input; precise and infrastructure-less self-positioning; cognitive support and multi-sense AR interfaces, improving their focus and capability to utilise information; and robust ad-hoc intra-team communications for both verbal and data exchanges, all delivered over enhanced power and communication autonomy features.
H2020, 2021-2024, Principal Investigator, Budget: 7M Euro (University of Greenwich: 441K Euro)

C4IIoT Project

C4IIoT: Cybersecurity 4.0 - Protecting the Industrial Internet of Things

C4IIoT will build and demonstrate a novel and unified Industrial IoT cyber security framework for malicious and anomalous behaviour anticipation, detection, mitigation and end-user informing. Our role is to equip the framework with the ability to decide dynamically where to process the security-relevant data it collects in a manner that takes into account the performance, energy and security of the system.
H2020, 2019-2022, Principal Investigator, Budget: 6.3M Euro (University of Greenwich: 250K Euro)

SUN Project

SUN: Social and hUman ceNtered XR

The SUN aims at investigating and developing extended reality (XR) solutions that integrate the physical and the virtual world in a convincing way, from a human and social perspective. The virtual world will be a means to augment the physical world with new opportunities for social and human interaction.
Horizon Europe, 2022-2025, Co-Investigator, Budget: 7.48M Euro (University of Greenwich: 478K Euro)


EUNOMIA: User-oriented, secure, trustful and decentralised social media

The EUNOMIA project will provide a fully decentralised, intermediary-free and open-source solution for user-oriented trustful social media to help social media users take ownership of the disinformation problem
EU H2020, 2018-2021, Co-Investigator, Budget: 2.94M Euro (University of Greenwich: 512K Euro)


ENSURESEC: Safeguarding the Digital Single Market’s E-Commerce Ecosystem

The ENSURESEC project will be a sociotechnical solution for safeguarding the Digital Single Market’s e-commerce operations against cyber and physical threats. It combines an automatic, rigorous, distributed and open-source toolkit for protecting the e-commerce infrastructure, with monitoring of the impact of threats in physical space and a campaign for training SMEs and citizens aimed at creating awareness and trust.
EU H2020, 2020-2022, Co-Investigator, Budget: 9M Euro (University of Greenwich: 489K Euro)

Research Project Participations

EPSRC (GR/S52360/01) on Self-Aware Networks and QoS: Developed the first network admission control mechanism able to take into account multiple criteria set by individual users of the network, resulting in markedly reduced congestion and improved quality of service.

DIF DTC HYPERION on Automated and Adaptive Information Management: Developed a smart networking protocol that was naturally resilient to failures and worms through self adaptation, using Random Neural Networks

BAE/EPSRC ALADDIN on Dynamic Distributed and Decentralised Intelligent Systems: Extended previous work to develop a distributed multi-criteria admission control mechanism for communication networks

TSB/EPSRC SATURN on Resilience of the UK Critical National Infrastructure: Carried out research on self-aware networking for critical national infrastructures.

FP7 FIT4Green on energy-aware data centre technologies: Developed a distributed mechanism for minimising a large network’s energy cost by regulating user admission in an automated manner, and experimentally evaluated the tradeoff between performance and energy cost
