Personal

I am a postgraduate student and lecturer at the University of Stellenbosch, in the Division of Applied Mathematics, Vision and Learning Group. I majored in Electronics Engineering with Computer Science, and completed my MSc as a member of the Digital Signal Processing Group. The university is located in the beautiful village of Stellenbosch and, students being students, our campus probably has a lot in common with yours. The yearly SANUM conference may provide a good excuse to visit us!

Before you can have a PhD, you must learn how to tie your own shoelaces!
