About Me

I'm a final year PhD student at School of Computer Science in College of Computing at Georgia Institute of Technology (GT SCS), advised by Ada Gavrilovska.


At Georgia Tech, my research interests evolve around the area of Operating Systems, focusing on the memory management layer. More specifically, I work on designing and building methods for optimizing application performance in systems with heterogeneous memory components.


Prior to Georgia Tech, I received an undegraduate Diploma on ECE, with major in Computer Science, at the School of Electrical and Computer Engineering at National Technical University of Athens in Greece.


This student profile featured in GT SCS news nicely summarizes my academic journey.
