Portrait of Stavros Volos

Stavros Volos

Senior Researcher


I am a researcher in the Confidential Computing research theme at Microsoft Research in Cambridge, UK. My research interests are in the area of computer architecture with aspects of semiconductor technologies, computer systems, and security. My current research centers around confidential computing; in particular, new forms of trusted execution and side-channel resilience. Our vision on confidential GPUs presented in our paper “Graviton: Trusted Execution Environments on GPUs” is being realized by NVIDIA and Azure.

Prior to joining Microsoft, I completed my Ph.D. in Computer Science at the School of Computer and Communication Sciences, Ecole Polytechnique Federale de Lausanne (EPFL). There, I co-architected CloudSuite, a widely adopted benchmark suite for scale-out cloud services, and worked on processor architectures and memory systems for scale-out datacenters. CloudSuite (along with our initial scale-out server characterization) laid the foundation for the first generation of Cavium ThunderX server CPUs.
