Short CV

I matriculated in Piet Retief in Mpumalanga, South Africa, in 1982. I received my tertiary education at the University of Pretoria (1983-1986), University of South Africa (1991-1994), and the University of the Free State (1997-1999). My PhD thesis was entitled: The Presentation of a Model of an Electronic Patient Record System for use in General Practice in South Africa. I have been happily married to Frikkie for the past 35 years and we have three daughters: Elsa, Estie and Lize.

I started my career working for the The Togaat Hulett-Group (Pty) Ltd with whom I held a scholarship, in Kwa-Zulu Natal, first as treasury assistant, and later as marketing analyst (1987-1990). In 1991 I was appointed as Computer Scientist at the University of South Africa in Pretoria and promoted to Senior Computer Scientist in 1993. In 1995 we moved to Bloemfontein where I started my academic career at the University of the Free State, first as Lecturer, then in 2001 as Senior Lecturer, and as Associated Professor from 2021. Therefore i have 30 years of experience in the academic environment.

I taught a variety of subjects, namely the Introduction to computers for scientific environments, Introduction to computers for business environments, User Interfaces, Introduction to databases and database management systems, Project Management (Honours), and User Interfaces (Honours and Masters). 

I also served as Programme Director for B.Sc. (IT) at the UFS for 6 years until 2008.

Research focus: My research focus for the past few years has been on Human-Computer Interaction (HCI), specifically on the evaluation of usability and the user experience (UX). This involves different application domains where a variety of methods are applied in evaluating the usability and UX. One of these application domains involve Brain-Computer Interfaces (BCIs) where physiological evaluation is performed using brain wave patterns of participants to deduct their UX at the time of interacting with a computer product. I have also started working with post-graduate students in the area of Virtual Reality (VR), for example in the training of nursing students and the training of undergraduate students to assemble a personal computer. Publications will be listed in this document.

Currently I am teaching modules in HCI on 2nd, Honours and Masters’ levels, and am in charge of the Honours Research Methodology module. I have also been involved in teaching modules like C++ Programming, Databases and Project Management over the past few years. In 2008 I received the Teaching & Learning Award from the Faculty of Natural & Agricultural Sciences for excellence in the field of teaching and learning at the University of the Free State. In 2019 I received my UFS 25 Year Service Award. I have successfully been the supervisor and promotor for Masters’ (12 students) and PhD students (5 students). Of the 12 Masters’ students whom I have supervised, 7 obtained their degrees Cum Laude, while 3 of the rest obtained a final mark of 70% or higher. For the past 25 years I have also been supervisor between one and three Honours Project per year.

In the academic community, I have been recognised as knowledgeable and one of the leading forces in HCI teaching and research in SA. I won the departmental Flash Fact Research Competition in the Department of Computer Science and Informatics in June 2022. In June 2022 I received the Best Reviewer in the IT Track Award at the SAICSIT 2022 Conference that took place in Cape Town July 2022. I have been asked to perform as external examiner for Master’s and PhD students for a variety of universities, including the University of South Africa (UNISA), University of Pretoria (UP), University of Cape Town (UCT), RHODES, Central University of Technology (CUT), University of Johannesburg (UJ) and the Nelson Mandela Metropolitan University (NMMU). I also act as external moderator for these institutions (numerous modules).

I have served on the programme committees of various national and international conferences (SACLA, SAICSIT, ECIS, HISA, HIMJ, ACCC, CHIRA. IARIA and ICACCE) and have served as referee for national and international journals, like the South African Computer Journal (SACJ), Journal for Organizational End User Computing (JOEUC), African Journal of Technology, Innovation and Development (AJTID), International Journal of Human-Computer Interaction (IJHCI) and the Journal of Information Security and Applications (JISA). I have been the only South Africa representative on the Editorial Board of the JOEUC from 2002 until present, and in 2023, I was asked to join the Editorial Board of Frontiers in Neuroscience (Brain-Computer Interfaces).
