I am lecturer in the Department of Pure and Applied Mathematics at the University of Johannesburg, South Africa. I teach calculus to first-year Bachelor of Science (BSc) students. I also teach an Honours (4th year) course in Set Theory. I obtained both my undergraduate and Masters degrees from Rhodes University, Grahamstown, South Africa. I completed my DPhil (PhD) at the University of Oxford, UK. I am interested in effective online methods for learning and assessment of undergraduate mathematics.
