I am a PhD candidate at the Large-Scale Data & Systems Group from the Imperial College London under the supervision of Peter Pietzuch. My research interests cover systems, security, containers, and virtualization.

About Me

My main research interests lie in the broad area of (distributed) systems, virtualization, and security, with a strong mathematical foundation. As part of my PhD, I am working on high-performant serverless runtimes using WebAssembly for execution isolation in the context of Faasm. Current lines of work involve achieving high performance with stateful serverless workloads, efficient and infrastructure aware scheduling, and putting Intel SGX in the mix. All my work is open-source and accessible through my Github.
