Dimitris Mitropoulos
Associate Professor, National and Kapodistrian University of Athens
Head of the Reliability Engineering and Cybersecurity Directorate, GRNET
I am an Associate Professor at the National and Kapodistrian University of Athens (NKUA) in the Department of Business Administration, and Head of the Reliability Engineering and Cybersecurity Directorate at the National Infrastructures for Research and Technology (GRNET), where I lead the design and implementation of advanced infrastructures supporting governmental and academic services used by millions of Greek citizens.
I earned my Ph.D. in Secure Software Development Technologies from the Athens University of Economics and Business, where I was advised by Professor Diomidis Spinellis and worked as a Postdoctoral Researcher in the Computer Science Department at Columbia University with Professor Angelos Keromytis.
I am interested in building software that is both reliable and secure. My research combines ideas from software engineering, computer security, programming languages, and systems. I believe in bridging the gap between theoretical advances and practical tools that can be adopted in real-world settings.
