CV
Eirini Liotou is an Assistant Professor at the Department of Informatics and Telematics of Harokopio University of Athens since 2024. She holds a PhD degree from the Department of Informatics and Telecommunications at the National and Kapodistrian University of Athens. She obtained the MSc in Informatics and Telecommunications from the same university, the MSc in Communications and Signal Processing from the Imperial College of London, and the Diploma in Electrical and Computer Engineering from the National Technical University of Athens. She has worked as a Senior Software Engineer at Siemens Enterprise Communications in the R&D department. She has also worked as a Post-Doc researcher in the Department of Informatics and Telecommunications at the National and Kapodistrian University of Athens, and as a Scientific Project Manager for EU Research Projects at the Institute of Communications and Computer Systems (ICCS). She has authored more than 50 peer-reviewed publications, and she has participated in numerous research and development programs. She also serves as a Reviewer for EU projects (as an EC expert). Her main research interests revolve around 6G mobile networks, with a particular focus on Software-Defined Networking (SDN), Network Functions Virtualization (NFV), AI in networking and network emulation, as well as Software-Defined Vehicle (SDV) and V2X communications.
