CV
Vassilis Dalakas (SMIEEE) holds a Ph.D. in Informatics and Telecommunications and has extensive experience and leadership in the fields of cybersecurity, digital transformation, cloud infrastructures, and telecommunications systems.
He received his Ph.D. in 2010 from the Department of Informatics and Telecommunications at the National and Kapodistrian University of Athens, focusing on the development and simulation of advanced techniques for performance optimization of satellite communication systems over nonlinear channels (with honours). He also holds an M.Sc. in Signal Processing and Information Systems (2002, with honours) and a B.Sc. in Physics (1998).
Since 2019, he has served in a strategic advisory role at the Ministry of Digital Governance of Greece, contributing to the design and implementation of large-scale national digital transformation initiatives. He has played a central role in the development and evolution of critical national infrastructures, including the Government Cloud (G-Cloud) and the SYZEYXIS II national telecommunications network, supporting technology decisions that impact hundreds of public organizations and thousands of information systems. His work includes the design of secure cloud architectures (IaaS/PaaS/SaaS), the development of cybersecurity governance frameworks, and risk management for critical digital infrastructures. He also acts as a key liaison with national and international stakeholders in cybersecurity incident response and resilience.
Since 2014, he has been a member of the Laboratory Teaching Staff at Harokopio University of Athens, contributing to teaching and research in telecommunications and system simulation. He has taught both undergraduate and postgraduate courses and supervised numerous student theses, actively contributing to the education of the next generation of engineers and researchers. In parallel, he has played a key role in the design, deployment, and operation of large-scale cloud and ICT infrastructures in the academic sector.
His research interests include satellite communications, system modeling and simulation, cloud computing, and large-scale information systems. He has participated in numerous European research projects (H2020, ESA, among others), undertaking roles in technical coordination, project management, and security consulting. He is the author of a significant number of publications in international journals and conferences, with contributions that bridge theoretical research and real-world applications.
He has contributed to the development of international standards (ETSI DVB-RCS2) and has been a Senior Member of IEEE since 2015. He has also contributed to major public sector digital transformation projects that have received international recognition, including the WITSA Global Innovation and Tech Excellence Awards (2023 and 2024), highlighting the impact of his work at both national and international levels.
He possesses extensive technical expertise in cloud technologies, networking, cybersecurity, software development, and data analytics. He is fluent in English and has a good command of French and German.
