General

Since December 2025 I am an assistant professor at the Department of Informatics and Computer Enginneering of the University of West Attica. Before joining the department I worked as a Lecturer and/or as a PostDoc at the National Technical University of Athens (NTUA), the Athens University of Economics and Business and the Cockrell School of Electrical and Computer Engineering of the University of Texas at Austin (supervised by prof. Evdokia Nikolova). I got my PhD from the School of Electrical and Computer Engineering of NTUA, under the supervision of prof. Dimitris Fotakis and prof. Stathis Zachos. Prior to that, I had completed the Graduate Program in Logic, Algorithms and Computation, after taking a diploma from the School of Applied Mathematics and Physics of NTUA. My pre-academic years were spent in my birth place, Sparta. A CV of mine can be found here.
