Prof Lizette de Wet
Prof Lizette de Wet is of the opinion that there is no gender distinction between what women and men could achieve in the field of Computer Science and Informatics.

“I consider obtaining my PhD while balancing my work, my marriage, and two young daughters (who did not sleep through before reaching age four!) as one of my biggest achievements,” says Prof Lizette de Wet, Associate Professor in the Department of Computer Science and Informatics at the University of the Free State (UFS).

Many firsts

Her achievements in the field include much more than the PhD referred to. On 11 February, International Day of Women and Girls in Science, the UFS celebrates her for pioneering the human-computer interaction (HCI) research environment, specifically the evaluation of usability and user experience in diverse application areas, where she has experienced and established many firsts.

Prof De Wet was one of the first students to complete a master’s degree in this discipline at UNISA (1994). She says the external examiner for her master’s was from the University of York in the UK, as expertise in South Africa was still lacking at the time.

In the Department of Computer Science and Informatics at the UFS, she established the HCI research area. This involved undertaking research projects in the discipline and developing curricula for a second-year module, an honours module, and a master’s module. 

“The second-year module was also one of two modules on campus to first use iPads in class to assist in a blended learning approach,” she says.

A woman’s contribution

Prof De Wet believes that in the research field of HCI, the focus is on the user and his/her overall user experience (including emotions, feelings, and competence) when using computers. “Taking the human being into consideration is much more important than simply concentrating on the programming code that needs to be written.”

Whether the human being writing the code is male or female, does not matter. Prof De Wet is of the opinion that there is no gender distinction between what women and men could achieve in the field of Computer Science and Informatics. 

“Although the students are still predominantly male, in the past few years more and more female students have enrolled for our postgraduate studies and completed it successfully, some of them with exceptional marks. In South-Africa, many women are making their mark in this discipline by being heads of departments at universities or in the private sector, by chairing national and international conferences, and by publishing ground-breaking research,” she adds.

Success with virtual reality

Over the past few years, Prof De Wet has concentrated on using brain-computer interfaces (BCIs) and virtual reality in her research. By the end of 2020, she had successfully supervised 11 master’s students and four PhD students, with one of the master’s students delivering ground-breaking research using virtual reality in the training of nursing students.

She elaborates: “The prototype involved virtually examining and evaluating a patient (with a foreign object lodged in a lung) in a virtual ward while wearing an Oculus Rift headset. The evaluation results were extremely positive and will be continued as a PhD study to investigate how to attempt to relieve motion sickness in an immersive virtual clinical simulation.”

Starting out as someone who never had the opportunity to lay her eyes on a computer during her school years, Prof De Wet is of the opinion that in South Africa – being a Third World country – there are numerous opportunities to make computers accessible to rural communities, and even to the large senior population who did not grow up with technology and might fear it.

With her passion for the profession, she not only delivers pioneering work, but also trains professionals in computer sciences who will contribute to a better tomorrow.

Prof. Aldo Stroebel serves on SAYAS
2011-09-23

 

Prof. Aldo Stroebel


Prof. Aldo Stroebel, from our university, has been elected as a Founding Member of the South African Young Academy of Science (SAYAS).
 
He is currently Associate Professor in the Centre for Sustainable Agriculture, Rural Development and Extension, as well as the Director of International Academic Programmes in the Office of the Vice-Chancellor at the university.
 
The Young Academy has as its objectives to represent young scientists in advising the government on science and technology policy and human resource development. In addition, they will prepare the SAYAS to join the Global Young Academy (GYA) to engage with high-level international bodies, including the World Economic Forum. Twenty Founding Members have been elected – ten new members will be elected annually to a maximum of 50.
 
Prof. Stroebel obtained his master’s degree at the University of Ghent, in Belgium, and a PhD at the UFS after a year of graduate coursework at Cornell University in the USA. He completed post-doctoral work at Wageningen University and Research Centre in The Netherlands, where he has been appointed as a Visiting Fellow to their recently-established Centre for Food Security and Sustainable Development. He has published widely, including more than 90 journal articles, book chapters and reports, and co-edited a book published by CTA Wageningen. He has supervised ten master's and doctoral students.  
 
He serves in various capacities: he is a member of the Research and Innovation Strategy Group of Higher Education South Africa (HESA), former member of the SANPAD Board, the President of the International Network of Research Management Societies (INORMS) Conference in 2010, and Vice-President of Research and President-elect of the Southern African Research and Innovation Management Association (SARIMA).
 
Prof. Stroebel has participated in a number of national and international conferences. He was a keynote speaker at the Society of Research Administrators (SRA) in Washington DC in the USA and at the Ministerial Conference on Higher Education in Agriculture in Uganda.
 
He has worked as a consultant and/or advisor for a number of international and multinational organisations, including the Food and Agricultural Organisation of the United Nations (FAO), the United States Agency for International Development (USAID), World Bank, Lux Development, and the World Conservation Union (IUCN), Switzerland.
