Vasileios Giotsas

Lecturer in Computing and Communications, Lancaster University

Vasileios Giotsas is a Lecturer at the Computer and Communications department of Lancaster University since 2018. Previously, he worked as a research scientist at the Internet Measurement and Analysis group of Technischen Universität Berlin (2017), and as a postdoctoral researcher at CAIDA (Center of Advanced Internet Data Analysis) at the University of California San Diego (2013 - 2017). He obtained his Ph.D. in Internet Cartography and Network Modeling from University College London (UCL) in 2013. He was involved in multiple mission-critical research projects funded by the US Department of Homeland Security (DHS), and the Space and Naval Warfare Systems Command (SPAWAR), and UK's National Cyber Security Center (NCSC) through which he developed expertise in the operational aspects of risk assessment and mitigation for national cyber-defence and security. His research focuses on novel network measurement and large-scale data analysis techniques to advance our ability to identify, monitor, and model the interconnection structure of critical cyber-infrastructures, improve our situational awareness, and defend against cyber threats, including Denial of Service (DoS), traffic hijacking and traffic misdirection attacks.

Vasileios has served as organizer and reviewer for top-tier networking conferences and journals, including ACM SIGCOMM, ACM CoNEXT and ACM IMC, the IEEE Journal on Selected Areas in Communications (SAC), IEEE Communications Letters, and the ACM Transactions on Internet Technology (TOIT). H has contributed multiple open-source tools and publicly accessible datasets for the collection and analysis of routing data and security incidents, which are being used by over 100 companies and research groups around the world. His work has been distinguished with the CoNEXT 2015 best paper award, and IETF Applied Networking Research Prize 2016, and his datasets have been shortlisted in 2013 and 2014 for the ACM SIGCOMM Community Contribution Award.
