I work as a Research Fellow for the Scientific Computation and the Visualization and Virtual Reality research groups in the School of Computing at the University of Leeds.

Research

My research interests are in the solving of numerical problems described by PDES, in the application of parallel computing and Grid technologies, and in the efficient visualisation of large datasets.

In the following pages my work, past and present, is summarised. Links to papers and talks available online are provided.

Elastohydrodynamic lubrication - funding from EPSRC, Shell Global Solutions and the DtI

Description of the physical problem
PhD work on variable timestepping and mesh adaptation
PhD work on mesh adaptation
ROPA work on Problem Solving Environments (PSEs)
ROPA work on Parallelism
e-Science work on doing all the above on the Grid
e-Science Grid Optimisation work - GOSPEL

Skin - funding from the EPSRC Life Sciences Interface Programme
Volume rendering - funding from the IECOE and the Numerical Algorithms Group (NAG)
- Production of a module for IRIS Explorer using VTK's Volume Rendering algorithms
Integrative Biology e-Science project
- Multivariate visualisation of numerical heart models
- 3-d visualisation of high resolution MRI datasets - winner of the vizNET Showcase 2008

Further information on these projects is available from the CPDE Unit and IRIS Explorer Centre of Excellence webpages

The automatically generated complete list of my publications (excluding my PhD thesis) is also available. Preprints of papers that have not appeared yet can also be found on the downloads page.

Images from some of my work were entered into the Faculty of Engineering research image competition 2008 and the 'Skin Deep' entry won first prize.

Research supervision

As part of my work I am involved with work with two PhD students. Both projects have come out of the EHL modelling described above.

Comparison of very fine grid finite difference multilevel schemes to Discontinuous Galerkin finite elements for both line and point contact cases (work with H. Lu)
Adjoint error estimation for grid adaptivity based on quantities of interest for line contact EHL (D.E. Hart)

Teaching

As part of the department's undergraduate programmes a course on Practical Parallel Programming has been offered. Each year since 2002 I have given several of these lectures, namely on 'Using MPI' and 'Threads'. Links are provided via the SE31 course page. I have also taught on the MSc course in Future Directions Computing course lectures on 'Grid Computing'. Also in 2007 I have taught first year lectures on LaTeX (in SS11) and research programming in Scientific Computing (in SS12).

Multimedia downloads

There are always people wanting pictures and movies. The downloads page should provide links to whatever is needed that I have available. Full downloadable versions of all my papers are also provided from here. If you know a file exists but can't find it, then e-mail me.

Reference material

There are many tricks we learn when using computer systems that are only spread by word of mouth, and by experience. If they are things we do infrequently then often they need relearning. By collecting these tips together we can preserve the information better. The pages of information - intended for local use on our computer systems here at the time of writing, but probably applicable more widely - are the following.

LaTeX Tips including preparation of documents for PDF screen display, formatting of slides with EPS figures and how to get IRIS Explorer images looking good.
Debugging parallel MPI jobs using dbx - intended for use on our Solaris system.

Comments to me please.
