Hello,

I am an Assistant Professor at the MNS group of the Institute of Informatics, as the University of Amsterdam. My research focus is on network softwarization and programmability including software-defined networking, network slicing and orchestration and AI/ML-driven network intelligence and automation for next generation networks.

I completed my Ph.D. in Electrical and Computer Engineering at the National Technical University of Athens. In the following, I worked as a post-doc researcher at the NETMODE lab (ECE/NTUA) and then as a Research Scientist for the Institute for Systems Research, at the University of Maryland, with a joint appointment at the Department of Electrical and Computer Engineering. Prior to joining UvA, I worked as a network research engineer for the End-to-End Network Service Automation Lab in Nokia Bell Labs (Belgium).
