Giorgos Vasiliadis

About Me

My name is Giorgos Vasiliadis (alternate spellings: Georgios Vasileiadis) and I originally come from Crete [1]. Currently, I am an Assistant Professor at the Department of Management Science and Technology of the Hellenic Mediterranean University and a collaborating researcher with the Institute of Computer Science at the Foundation for Research and Technology - Hellas. Before that I was a Research Scientist for the Cybersecurity lab at Qatar Computing Research Institute. I have got my PhD in Computer Science from the Computer Science Department at University of Crete. At the same time I was working as a research associate at the Distributed Computing Systems Laboratory of the Institute of Computer Science, at the Foundation for Research and Technology, Hellas (FORTH-ICS). In 2013, I spent three wonderful months at Symantec Research Labs in Los Angeles, as a research intern under the supervision of Petros Efstathopoulos.

I am honored to receive the prestigious Symantec Research Labs Graduate Fellowship (2012) and the Maria M. Manassaki Bequest Scholarship (2013). I have served as publicity chair for RAID (2015) and program committee member for ISC (2024, 2023), CANS (2022, 2023, 2024), CCSW (2019, 2020, 2021, 2022, 2024), EC2ND (2011), EuroSec (2012, 2013, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024), IWSEC (2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024), EUSPN (2022, 2024), SecHealth (2022, 2023, 2024), SecMT (2022, 2023), ICPADS (2016), WIFS (2016, 2017, 2018, 2020), AINA (2021, 2024), ISCC (2017), and IOSec (2019, 2022). I have also served at the Research & Informatic Corps of the Greek Army (2009).

My research has been published in top peer-reviewed conferences, e.g., ACM SOCC, ACM CCS, USENIX ATC, NDSS, IEEE TDSC, ACM TACO, IEEE/ACM ToN, IEEE Access, and has been cited over 1700 times, and has been recognized by important media such as Slashdot, The Register, Ars Technica, The Inquirer, ComputerWorld, PCWorld, and HotHardware.
