About me

I'm an Assistant Professor (Lecturer in the UK system) in the Department of Computing at Imperial College London and a visiting researcher in the Confidential Computing Group at Microsoft Research Cambridge. I work at the intersection of operating systems, networking, and distributed systems and build systems that can provide tail-tolerance, fault-tolerance, and confidentiality guarantees leveraging emerging datacenter hardware.

Before joining imperial was a researcher at Microsoft Research Cambridge. I obtained my PhD in 2020 from EPFL under the supervision of Ed Bugnion. My thesis was awarded the 2021 Dennis M. Ritchie Award and the 2021 Honourable Mention for the Eurosys Roger Needham PhD Award. My PhD was supported by an IBM Fellowship and the Microsoft Swiss JRC. I did my undergrad in Electrical and Computer Engineering at NTUA.

I'm always looking for motivated PhD students and interns! If you are an Imperial student don't hesitate to reach out to me if you are interested in working on a project beyond the ones listed in the projects portal.
