Welcome
to my university web page.
In 2009-2010 I have been with the Computer Laboratory and I am now with the Statistical Laboratory at the Department of Pure Mathematics and Mathematical Statistics. My principal research interests include stochastic modelling and statistical inference, as well as optimal experimental design problems; priority queueing systems with switchover times, polling systems; optimisation on graphs and networks; random matrix theory and its applications.
While I am currently looking into mathematics of energy and power network systems, I have recently been working on the TIME-EACM project, which explored how sensor networks and distributed systems can be used in order to improve transport traffic management and control. In particular, I was working on statistical modelling and analysis of sparse urban transport traffic data.
My previous research includes a PhD in Operational Research on `Switchover Time Modelling in Priority Queueing Systems' and a PhD in Statistics on `Inference and Experimental Design for Percolation and Random Graph Models'. In my MSc thesis I was interested in the spectral analysis of sample covariance matrices: specifically, the dissertation discussed computational aspects and numerical realisation of the Tracy-Widom distributions as well as the solution to Painleve II differential equation (with realisations in R/S-Plus).
I supervise Part IA Computer Science Tripos students of Robinson College in Probability Theory, Part IB Mathematical methods for Computer Science and Part II Computer Systems Modelling students from Clare/Emma/Girton/Selwyn/Sidney colleges group.
My CV is available here.
