Ever tried. Ever failed. No matter. Try again. Fail again. Fail Better” - Samuel Beckett


  • I did my BSc (Computer Science and Statistics), BSc (Hons) (Computer Science) and MSc (Computer Science) degrees in the Department of Computer Science at the University of Cape Town in South Africa.


  • I'm now a Professor of Applied Quantitative Analysis in the Department of Computing at Imperial. My broad area of research interest is the application of mathematical modelling techniques to real life systems. Specific areas of interest include, but are not limited to, modelling and optimisation in parallel queueing systems (especially split-merge and fork-join systems), modelling of storage systems, stochastic modelling of sport, stochastic modelling of healthcare systems, resource allocation and control in cloud-computing environments, numerical solution of (semi-)Markov models and specification techniques for SLA specification, compliance prediction and monitoring.
