Giorgos Vasiliadis

My name is Giorgos Vasiliadis (alternate spellings: Georgios Vasileiadis) and I originally come from Crete [1]. Currently, I am a Research Fellow for 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, under the supervision of Prof. Evangelos Markatos and Dr. Sotiris Ioannidis. 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 EC2ND (2011), EuroSec (2012, 2013, 2016, 2017, 2018), IWSEC (2016, 2017, 2018), ICPADS (2016), WIFS (2016, 2017, 2018), and ISCC (2017). 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. RAID, ACM CCS and USENIX ATC, has been cited over 1000 times, and has been recognized by important media such as Slashdot, The Register, Ars Technica, The Inquirer, ComputerWorld, PCWorld, and HotHardware.

A graphical desktop search application that was started on my spare time, enabling the user to search documents, music, photos, web pages and more that are stored locally on a computer. It is written in Java and it is portable to both Linux and Microsoft Windows. The project is open-source and it is available online at http://puggle.sourceforge.net.
