I am a fifth-year PhD student at the Large-Scale Data and Systems Group (LSDS) of the Imperial College London, under the supervision of Prof. Peter Pietzuch.

My research addresses the design and implementation of secure, high-performance, runtimes for the cloud. I am particularly interested in serverless and confidential computing. Most of my work is open-source and available on Github. During my PhD, I have interned at Intel Labs, IBM Research and Microsoft Research (incoming summer 2025).
