Portrait of Stavros Volos

Stavros Volos

Senior Researcher


I am a researcher in the Confidential Computing research theme at Microsoft Research in Cambridge, UK. Between May, 2017 and November, 2018, I was affiliated with the Systems Group in Redmond. 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.

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.
