Partner Deputy Lab Director,
I am a Partner Deputy Lab Director at Microsoft Research, Cambridge, UK, and I lead a team looking at future technologies the cloud, called the Cloud Infrastructure Team. Many of the projects we run in the Cloud Infrastructure Team are focused on creating and exploring new optical-based technologies for the cloud (for more information see #OpticsForTheCloud) – across storage, compute and networking.
As part of the Cloud Infrastructure Team, I set up and lead an embedded joint Microsoft Research/Azure Storage lab called the “Azure Storage Research Lab” (ASRL). ASRL has the goal to develop future storage technologies targeted at the cloud, and an example of the sort projects the lab does is Project Silica which is looking at how to store data in Fused Silica (basically glass) as a replacement for tape for long term archival storage. For a rather old overview of Project Silica see our HotStorage paper: Glass: A New Media for a New Era?
Project Silica has been a large part of my life for the last three or so years. There has been a lot of media and Microsoft coverage of Project Silica and the broader Optics For The Cloud Agenda since Satya talked about the project in his keynote at Ignite on 4th Nov 2019.
A key part of this is the announcement of the work we have been doing with partners to write their content into glass. The picture of the hand is showing a glass platter into which we have written a film (75x75x2mm platter). To learn more about how we write the data take a look at this animation: https://www.youtube.com/watch?v=6CzHsibqpIs
To give an idea of progress we are making in Project Silica, here is an image taken around a year ago (in 2018), which shows a 25x25x2mm glass platter with the Azure logo, and a few dots. Each dot represents a square of voxels and is a few tens of layers of data deep.
This is the same size platter today (25x25x2mm) into which we have written a Windows 10 ISO image now filling the full platter all the blue looking parts are full of data.
Sounds exciting? We are always looking for really talented people who would like to join the team, especially people who are interested in internships or post-doc positions, from a wide range of backgrounds.

I was deeply honored to be awarded the 2016 ACM SIGOPS Mark Weiser Award. I am a systems researcher working at the intersection of Storage, Networking, Systems and Distributed Systems. During my career, 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 original DHTs, called Pastry (Middleware’01), and of the first large-scale key-value stores (PAST SOSP’01). I’m proud to say that the original Pastry paper written with Peter Druschel was awarded the "Middleware'2011 10-year best paper award".
I try to select research themes to work on that I believe will have an impact in the real world. Often it turns out my belief is misplaced, but occasionally not! The work on distributed systems has had some internal impact; 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 (SOSP’03). We evangelized the work on Squirrel (PODC’02) to many teams, and then BranchCache was created.
Since moving to focus more on storage; IOFlow (SOSP’13) 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 2016 (see blog). Pelican (OSDI’14) is now owned by Azure.

Since May 1999 I have been working at Microsoft Research in the UK, where today I am a Partner Deputy Lab Director. 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 and a DPhil degree in Computer Science in 1997 both from the University of York, UK. After completing my DPhil studies, I joined Cambridge University in November 1996, initially as a Research Associate in the Computer Laboratory and then as a Senior Research Associate in the Engineering Department, Cambridge. During this time, I was a consultant for the Olivetti and Oracle Research Laboratory (ORL) (which became the AT&T Research Cambridge in 1998).
