I am currently a senior lecturer in the Electric and Electronic Engineering Department, Stellenbosch University, South Africa. I obtained my PhD at Stellenbosch University in 2015. My dissertation mainly focused on the deployment and control of solar sailing satellites. During and since my post-graduate studies I have been involved in a number of satellite missions and contributed in the development of a variety of satellite hardware mainly focused on attitude control. Current research focus is on creating control systems which adjust according to environment or the status of the vehicle itself.
I have taught the following undergraduate courses:
- Electro Technique 214 (Circuit Theory and Electric Machines)
- Computer Programming 143 (Introductory to Programming)
- Computer Systems 214 (Introductory to Computer Systems)
- Computer Systems 414 (Embedded Systems)
- Control Systems 314 (Feedback Control)
