Personal

I am a post doctoral researcher at UC Berkeley, and a lecturer at Stellenbosch University, 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. In December 2010, the arduous journey of transforming myself into a doctor of engineering came to an end, producing as a side effect a dissertation on Super-resolution imaging. Our 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! (I recommend this one.)
