Evaluation of spin networks using group integrals:
I studied the theory of SU(2) spin networks as introduced by Roger Penrose. They can be evaluated combinatorially but also as an integral over SU(2). Supervised by John Hannay we understood how to go between the two methods and evaluated some examples combinatorially and via the integral. The review I wrote is available here. I also recommend John Baez' site for information about this topic and much more.
I was a summer student at CERN with the ALICE collaboration in 2011 and a Nuffield summer student with Sebastian Mueller in 2010. In summer 2012, I worked with Isaac Chenchiah and Jonathan Robbins on problems in vortex motion.
