Dimitris Mitropoulos

Welcome to my home page!

I am an Assistant Professor at the National and Kapodistrian University of Athens in the Department of Business Administration. I do research in the areas of software engineering and computer security. I received my Ph.D. degree in software security from the Athens University of Economics and Business. Prior to joining the University of Athens, I was a postdoctoral researcher in the Computer Science Department at Columbia University. I am a member of ACM, IEEE, and USENIX.

I also lead the Reliability Engineering Directorate of the Greek National Infrastructures for Research and Technology (GRNET). The directorate includes several teams such as the site and network reliability engineering groups and the organization's computer emergency response team.
