Georgia Fragkouli

I am a postdoctoral researcher at ETH Zurich in the group of Prof. Laurent Vanbever. Prior to ETH, I got my PhD from EPFL (2022), co-advised by Prof. Katerina Argyraki and Prof. Bryan Ford.

My focus is on improving and reliably measuring the performance of networked systems. First, I am exploring fair and efficient techniques for scheduling tenants in the data center, while respecting their potential differences in performance metrics. Second, I am exploring i) the consistency of end-to-end flow performance with in-network telemetry along the flow’s path [paper], and ii) transient violations of network forwarding properties during BGP re-convergence [paper], to improve network debugging.
