Research Activities

My research is in the overlap between Electronic Engineering and Computer Science.  My Ph.D. was carried out in the ‘Advanced Processor Technology’ group headed by Prof. Steve Furber within the School of Computer Science at Manchester University.  My Ph.D. thesis was concerned with the Monte Carlo simulation of large complex integrated circuits using the computational resources provided by parallel and distributed computing. The use of statistical simulation techniques for dealing with the ‘atomistic’ variability of nano-scale technology was at the heart of this project.  My main contribution was in reducing the computational complexity of the analyses through the use of statistical techniques such as ‘extreme value theory’ and ‘quasi-Monte-Carlo’ techniques.

I spent a year working as a fixed term Post-Doctoral Research Associate at Manchester Metropolitan University, working on a BBSRC project concerned with pattern recognition, machine learning, statistics and high performance computing. I designed a fine-grained parallel algorithm with MPI library for adapting data-intensive bioinformatics workflows to a distributed system (cluster) and the Cloud. My research adapted the concept of a ‘Petri Net’ to model ‘concurrency’ and ‘cost’ for automatically optimising the use of intermediate data storage and thus making more efficient use of Cloud resources.

I am currently working on efficient parallel computing, big data related issues and the use of web-based mobile digital signal processing (DSP) for biomedical applications.  I am working with Manchester Royal Infirmary (MRI) on a project concerned with monitoring the voice characteristics of patients suffering from ‘spasmodic disphonia’. I am also working on the analysis of voice characteristics over mobile devices.

I was the ‘Local Chair’ for an international conference in Manchester (IEEE EMS2013, UKSim-AMSS, 7th European Modelling Symposium on Mathematical Modelling and Computer Simulation), and acted as guest editor for a scientific journal: the ‘International Journal of Simulation: Systems, Science and Technology’. I am the Local Chair for IEEE EMS2017 in Manchester.
