iPODS: Intelligent Performance Optimisation of Virtualised Data Storage Systems

My research interests centre around performance analysis, particularly parallel and distributed tools and techniques for the analysis of very large Markov and semi-Markov models. I am also currently investigating the performance modelling of virtualised data storage systems.
