## Personal profile

### Research interests

Qualifications: BSc (1st Class Hons, Edinburgh, 1970), MSc (Oxford, 1971), DPhil (Oxford, 1974)

My main research is in Numerical Analysis and Scientific Computing, including both analysis of numerical algorithms and applications.

More specifically, at the moment, my main interests are:

- `Large Sparse Matrix Computations and Eigenvalue Problems', with, for example, application to stability of compressible and incompressible fluid flows;
- `Analysis of Networks and their Applications', with applications in Bioinformatics, including understanding how data errors affect algorithms for clustering;
- `Iterative methods for the Neutron Transport equation', including the analyisis of preconditioners within a diffusive regime.

More details can be found on my web page.
