Paul Barham Principal Researcher I am currently a Principal Researcher at Microsoft Research Cambridge, where I lead the Systems and Networking group. My research interests include performance analysis of distributed systems, operating systems and virtualization. Recent projects include Magpie, Constellation, Anemone, Singularity, Vigilante and Xen. I obtained my B.A. in Computer Science from the University of Cambridge in 1992 and my Ph.D. in 1996 for the Nemesis operating system. I continued research in the Systems Research Group at the Computer Laboratory as a Research Fellow of Christ's College, Cambridge. Before I joined Microsoft Research, I worked on devices and operating system abstractions for the Desk Area Network, Quality of Service for I/O and virtual memory in the Nemesis operating system, and resource allocation using on-line measurement techniques in the Measure project. When I'm not working I'm often rowing.
