I am a final-year Ph.D. candidate in Electrical Engineering at the Department of Electrical Engineering at Stanford University advised by Christos Kozyrakis. My research has been supported by the Stanford EE Departmental fellowship, A.G. Leventis Foundation, a Gerondelis Foundation Graduate Study Scholarship, and a Facebook Research Award.
I am broadly interested in computer systems, cloud computing, and scheduling. I have worked on end-host, rack-scale, and cluster-scale scheduling for microsecond-scale tail latency. Recently, I am looking for ways to make it easier to implement and deploy custom scheduling policies across different layers of the stack.
I hold a M.Sc. in Electrical Engineering from Stanford University. Before coming to Stanford, I worked for a year on distributed storage for the cloud at Arrikto. I received my undergraduate degree in Electrical and Computer Engineering from National Technical University of Athens in Greece, where I was advised by Nectarios Koziris.
In Summer 2017, Summer 2018, Summer 2019, and Fall 2019, I worked as a PhD intern at Google for the NetInfra and Borg teams in Sunnyvale, CA.
I will be an Assistant Professor of Computer Science at Columbia University starting July 2023. Before that, I will spend a year at Google SRG
