- I'm now a
Reader in Applied Performance Modelling in the Analysis, Engineering,
Simulation and Optimization of Performance
(AESOP) group 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), 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.

PIPE2 is a free, extensible,
platform-independent, open source Petri net editor/analyser developed by several
generations of MSc students at Imperial under my supervision (note DNAnet and DaNAMiCS are no longer
available or supported). PIPE2 is the current active branch of the PIPE Petri
net editor project, with over 60,000 downloads to date.
