Personal profile

Research interests

My research is in probability and its application to modelling real systems. This has so far concentrated on applications to communication networks but has also included social networks. In the future I will be exploring problems in power networks and cloud computing. More superficially I have worked on the application of large deviations to queueing systems with many sources. This involved the development of novel scalings which provided new insight into observed phenomena and the model of internet routers. In addition to this I have worked on models for information spread in social networks and novel methods for change point detection.


I completed my PhD in Cambridge under Prof F.P. Kelly and Dr D.J. Wischik. After this I spent two and a half years as a research fellow at the Heilbronn Institute for Mathematical Research in Bristol. In January 2011 I moved to the Actuarial Mathematics and Statistics department of Heriot Watt to take up a lectureship.
