Research Interests
My research interests include combinatorics, algorithms and coding theory, including some applications to bioinformatics.
Prospective Students: If you are a student considering completing a Master's degree or an Honours project and you are interested in any of the above topics, then please contact me. Students should be motivated and comfortable with mathematics (primarily discrete mathematics). Since it can be very difficult to evaluate applications, you should provide as much information as possible about your interests - for example, you might describe projects which you have already undertaken or in which you are interested.
I work closely with my students and ensure that all research students will have the opportunity to publish their work in journals or conference proceedings. You should also look at the list of projects completed by some of my past and present students. See my personal webpage for more information.
