I was previously (until the end of August 2009) a Postdoctoral Fellow at the School of Mathematics and Statistics, Carleton University, working under the supervision of Brett Stevens and Lucia Moura.

Before that, I was a PhD student at Queen Mary, University of London, where my supervisor was Peter Cameron, and an undergraduate student at the University of Leeds and the University of Waterloo.

• I taught the same course in Summer 2008 (jointly with Zhengmin Zhang). Click here for the course webpage.
• In the Winter 2008 term, I taught MATH3107 Linear Algebra III. Click here for the course webpage.

At QMUL:

• From April-June 2007, I taught the course SEJ015 Discrete Mathematics for the Science and Engineering Foundation Programme. I taught the same course in 2006.

Recently, most of my time has been spent working on the relationship between the base sizes of permutation groups and the metric dimension of graphs. A survey article on this topic is now available here.

Some specific topics (although not all are the subject of current research activity) include the following:

• Finite permutation groups
• Algebraic graph theory
• Other areas of graph theory, and matroid theory
• Covering designs and related objects (especially uncoverings-by-bases, perhaps my clumsiest contribution to the mathematical nomenclature)
• Permutation codes
• Other combinatorial problems involving algebraic objects (within reason!)

My PhD was completed in January 2006. My thesis was entitled Permutation Groups, Error-Correcting Codes and Uncoverings; it's about the use of permutation groups as error-correcting codes, and develops a decoding algorithm for them, which then led to questions related to covering designs. You can download it (as a PDF file) here; please let me know if you do.

You may have seen me at one of these conferences. A list of talks I have given can be found here.
