Teaching

Research Interests

My research interests include combinatorial optimization, algorithms (in the general sense), and computational intelligence. My research is directed at various application areas, including bioinformatics, coding theory and more.

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. Please also see my FAQ.

I work closely with my students and ensure that all research students have the opportunity to publish their work in journals or conference proceedings. You may also wish to look at the list of projects completed by some of my past and present students.

Online tables: Some of my papers consider the problem of establishing bounds on the number of codewords in optimal edit-metric codes and insertion-deletion correcting codes. Tables on these bounds are maintained at the following locations: Edit Metric Codes and Insertion-Deletion Correcting Codes.
