I am a principal researcher and I lead the Systems and Networking Team at Microsoft Research in Cambridge. My current research effort is focused on creating the technologies and systems that will underpin the future cloud- in particular focusing on hardware/software co-design of racks and storage.

Overview:

I do systems research at the junction of Networking, Systems, Storage and Distributed Systems and recently my work has been heavily focused on an area called rack-scale computers.  Over the years I have worked in several areas, including structured overlays or Distributed Hash Tables (DHTs), wireless routing protocols and even Robot Football (RoboCup’98). I worked on one of the first DHTs, called Pastry, and the 2001 paper on Pastry written with Peter Druschel was awarded the "Middleware'2011 10-year best paper award".

Several things I worked on have passed over from research to the wider world in one way or another - for example the work on Pastry directly contributed to both the Windows DRT API and the related Windows PNRP API (the former even includes a leaf set).  LiveStation licensed some of our P2P work around Pastry and SplitStream. Some of the work described in our IOFlow paper (SOSP’13) around opening up the storage stack and providing QoS primitives in the storage stack resulted in the SMB Bandwidth Limiting feature in Windows Server 2012 R2, and also inspired the end-to-end Storage QoS feature in Windows Server vNext (see blog posting).

 

Past projects with web sites:

·       CamCube

Short Bio:

For the last 17 or so years I have been working as a researcher at Microsoft Research in Cambridge, UK where I am now a Principal Researcher and lead the Systems and Networking Group. My research interests are broad, covering the spectrum of systems, distributed systems, storage and networking. In May of 2010 I was elected as a Fellow of the British Computer Society. I received an MEng degree in Computer Systems and Software Engineering in 1993 from the University of York, UK, and a DPhil degree in Computer Science in 1997 also from the University of York, UK.

In 1996 I moved to the Computer Laboratory at Cambridge University, UK as a Research Associate and then moved to the Laboratory for Communications Engineering in the Engineering Department, Cambridge University, as a Senior Research Associate. During my time at Cambridge University I was a consultant for the Olivetti and Oracle Research Laboratory (ORL) (which became the AT&T Research Cambridge in 1998 and has now sadly closed).  In 1999 I moved to Microsoft Research Ltd in Cambridge, UK.
