Efthymios Papageorgiou

Hi! I’m Efthymis Papageorgiou (Makis in short) and I’m a Ph.D. student in Computer Science at the University of Crete and a researcher at the Information Systems Lab at the Foundation for Research and Technology – Hellas (FORTH).

I work on cluster resource management for large-scale systems build on microservices. My focus is Quality of Service (QoS) of such systems - controlling tail latency and meeting service-level objectives (SLOs). A related interest is overload control: keeping systems steady when demand spikes within SLOs and avoid outages.

During my MSc, I explored how Proximal Policy Optimization (a reinforcement-learning method) can keep 99th-percentile latency under SLO on the DeathStarBench hotel-reservation workload.

When I step away from research, I tend to watch European basketball, read sci-fi by Liu Cixin or Asimov, play some bass guitar, or maybe just do nothing at all.

Feel free to reach out.
