I am a tenure-track faculty (Assistant Professor) at IMDEA Software Institute in Madrid, Spain.


During Summer 2022 I was a visiting researcher at the Institute of Informatics and Telecommunications at the National Centre for Scientific Research "Demokritos" in Athens, Greece.


I earned my PhD from the School of Computer Science in College of Computing at the Georgia Institute of Technology (Georgia Tech), advised by Ada Gavrilovska. At Georgia Tech, my research introduced system-level support for the resource management of extremely heterogeneous hardware. In particular, my dissertation adds machine intelligence to hybrid memory management. This graduation profile featured in GT Computing news and the Daily Digest nicely summarizes my academic journey.


During my PhD, I have interned at DellEMC in Santa Clara (CA, USA), VMWare in Palo Alto (CA, USA) and AMD Research in Bellevue (WA, USA), where part of my work has been patented.


Prior to PhD, I received an undegraduate Diploma in ECE, majoring in Computer Science, from the School of Electrical and Computer Engineering at National Technical University of Athens in Greece.


In 2020, I was selected as a Rising Star in EECS. Link GT News


In 2021, I received the Juan de la Cierva postdoctoral fellowship. IMDEA News

The Muse Lab

I lead the Muse research lab, where we are working at the intersection of Operating Systems, Machine Learning and Computer Vision (SysMLCV).
