I am working on a knowledge transfer project in association with the Met Office on 3D adaptive meshing for variational data assimiliation.

My PhD is on topology optimization of structures. This is a CASE award with the Rutherford Appleton Laboratory. Topology optimization addresses the problem of where to place material within a region in order to optimize a particular value of interest. We are particularly interested in buckling constraints - this means solving a large nonlinear eigenvalue constrained optimization problem.

My research interests include:
Linear algebra
Scientific computing
Optimization methods

My undergraduate project was on Numerical Methods for Two Parameter Eigenvalue Problems.

Publications

A fast method for binary programming using first-order derivatives, with application to topology optimization with buckling constants. With CJ Budd, NIM Gould, HA Kim, JA Scott. Accepted to the International Journal of Numerical Methods in Engineering. Available online here.

Useful linux commands

Combine two or more pdf documents together:

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=output.pdf pdffile1.pdf pdffile2.pdf

Remove pages from pdf document:

gs -sDEVICE=pdfwrite -dNOPAUSE -dQUIET -dBATCH -dFirstPage=m -dLastPage=n -sOutputFile=output.pdf input.pdf

Get the basename of a file (with only one . in its name)

basename=`echo $file | cut -d. -f1`

Get the type of a file (with only one . in its name)

type=`echo $file | cut -d. -f2`

Shell scripts

Note that all the following have been written by me so are probably full of bugs.

Aquila job submitting script - submit - for single node jobs written in FORTRAN compiled with goto BLAS

Simple printing script - myprint - currently only for the printer in 1W and automatically staples and prints in duplex

Pdf page removing script - removepages - to remove pages from a pdf document. Just a nice wrapper for the command above.

Rotating background script - background - a script to take a directory of photographs (jpg and png) and generate an xml file which can be used as a desktop background that rotates all the photos.
