(Update: I am now CEO of PetaGene. We tackle challenges in Personalised Medicine, making unwieldy genomic data from sequencers smaller, better and faster, to reduce costs, improve analysis and speed up collaboration.) My PhD research developed models for the physical locality of networks. Locality is fundamentally important for the performance of future computer systems with thousands of processors on a chip, but not much is fundamentally known about it. What is very exciting is that in collaborations with the Brain Mapping Institute, we've also found the theory can explain some mysteries of mammalian neuronal networks and we believe it may help to explain other natural phenomena where physical position matters such as social, epidemic, financial, and traffic networks.
