From July 2009 I've taken a year off to work on a storage startup
Acunu. We're hiring people with expertise in algorithms, kernel hacking and storage systems (send us an email at
jobs@acunu.com)!
I'm interested in graph algorithms and networks, in particular routing, broadcasting, load balancing, etc.� For my PhD I found a compact routing scheme for the `forbidden-set' problem: routing around induced forbidden subsets of a graph, with memory requirements O(k^2 polylog n) for treewidth k graphs.

From 1999-2002 I was an undergraduate at Warwick University. I did my PhD (forbidden-set compact routing) at the Computer Laboratory (and King's College) at Cambridge University from 2002-2006. I was a Marie Curie visiting fellow at BRICS in 2003 with Mogens Nielsen. After finishing my PhD I spent four months in 2006 at Microsoft Research Cambridge then a year from 2007-2008 as a Research Scientist at Thomson Research, Paris (my page there) where I worked on epidemic streaming algorithms mostly with Laurent Massoulie. From 2008-2012 I'm a junior research fellow (JRF) at St John's Oxford in the Computing Laboratory and the combinatorics group at the Maths Institute. A short cv can be found here. I've been lucky enough to work, visit and talk with many people, including Bruno Courcelle, Tim Griffin, Cyril Gavoille, Rahul Sami, Don Towsley, Laurent Massoulie, Elan Pavlov, Mihai Patrascu, Dan Tomozei, Peter Bro Miltersen and Mogens Nielsen.
