Ullrich, Senior Lecturer in Interdisciplinary Theology: Historical and Constructive Theology, obtained a Y1 rating. Bottom left: Prof Maria Tsakeni, Associate Professor in the School of Mathematics, Natural Sciences, and Technology Education, Prof Matildie Wium, Associate Professor in the Odeion School of Music, and Dr Weldemichael Tesfuhuney, a senior lecturer in the Department of Soil, Crop, and Climate Sciences, all obtained a C2 rating.

The list of National Research Foundation (NRF)-rated researchers at the University of the Free State (UFS) is growing, with 22 researchers recently receiving their first NRF rating, and 14 others obtaining new ratings after re-evaluation. This list is expected to grow even more with results slowly filtering in.

Profs Jan van der Watt, Research Fellow in the Department of Old and New Testament Studies, and Felicity Burt from the Division of Virology and SARChI Research Chair in vector-borne and zoonotic pathogens, are the latest NRF B1 rated researchers. While this is Prof Van der Watt’s first NRF rating, Prof Burt has increased her NRF rating from B3 to B1. The UFS now has 10 B1 rated researchers.

In addition to the new rating of Profs Burt and Van der Watt, the UFS also boasts seven new C1 rated researchers, 14 new C2s, five new C3s, seven new Y2s and one Y1 and B3 rated researchers respectively.

Among the researchers who obtained their first NRF ratings are Dr Bimo Abraham Nkhata, Senior Lecturer at the Centre for Environmental Management; Dr Yolandi Schoeman, Senior Lecturer in the Centre for Mineral Biogeochemistry; and Dr Angélique Lewies, Senior Lecturer in the Department of Cardiothoracic Surgery, who has this year been nominated for the prestigious 2023/2024 NSTF-South32 Awards, popularly known as the “Science Oscars” of South Africa. Dr Nkhata obtained a NRF rating in the C2 category, while both Drs Schoeman and Lewies obtained a Y2 rating.

An honour to be among rated researchers

Other researchers who obtained their first NRF rating include Dr Monique de Milander, Senior Lecturer in the Department of Exercise and Sport Sciences, who obtained a C3 rating and Prof Maria Tsakeni, Associate Professor in the School of Mathematics, Natural Sciences, and Technology Education, who received a C2 rating.

Dr De Milander, a Kinderkineticist who works with the motor development of young children, says she was very surprised to obtain a C3 rating. “I feel honoured receiving this NRF rating. To know that other researchers are reading my work and finding it relevant. It takes a lot of dedication and patience, since this is an endurance race and not a sprint. You need to work many hours, read a lot of new articles and write the articles themselves.

“In addition, collecting the data is not always possible without the assistance of our students at the Department of Exercise and Sport Sciences as fieldworkers. I would like to acknowledge them because without them my research projects would not always be feasible. Furthermore, the publication process is also timeous, thus a lot of time elapses before you start to see the results of your work,” explains Dr De Milander.

According to her, the current project for her NRF rating is the assessment of motor development, attentional deficit hyperactive disorder, anthropometry and academic performance in low- and high-socio-economic primary school learners in Mangaung.

Prof Tsakeni, whose research focuses on the design and implementation of innovative instructional strategies and curriculum innovations in science classrooms, says she is honoured to be among the rated researchers. “The recognition motivates me to continue pushing myself to climb the ladder of rated researchers. The rating makes me feel affirmed to continue with my research work. I am grateful to the Faculty of Education, the UFS, and the NRF for giving me the opportunity and support.”

She would like to upscale the impact of her research by engaging in large-scale studies, international comparative studies, international collaborations, and one day, be a visiting scholar at some prestigious universities.

“The innovations in science classrooms include integrating inquiry-based practical work, education for sustainable development (ESD) and STEM education. The instructional strategies include inquiry-based learning and integrating educational technologies in the classrooms,” says Prof Tsakeni.

Recognition for long-term academic work

Newly C2 rated researcher, Dr Weldemichael Tesfuhuney, a senior lecturer in the Department of Soil, Crop, and Climate Sciences, says: “As an agrometeorologist by profession, I feel a profound mix of pride and motivation after receiving NRF-rating recognition for my long-term academic work.

“This acknowledgment validates my years of dedication in understanding the intricate relationship between meteorology and agriculture. It boosts my confidence and reaffirms my commitment to advancing my academic and research goals.

“Such recognition is a pivotal moment for me; it serves as a powerful reminder of the impact of my research on agricultural practices, particularly in addressing the challenges posed by climate change in arid and semi-arid regions.”

Dr Tesfuhuney, whose research deepens understanding of how meteorological patterns affect agricultural practices, making a significant contribution to the field of Agrometeorology, has established a robust research portfolio focused on the challenges of meteorology and agriculture in arid and semi-arid regions. He has spearheaded several long-term research initiatives, including In-field Rainwater Harvesting (IRWH) techniques, intercropping practices, micrometeorology, and crop modelling simulations, all aimed at improving crop productivity for smallholder farming communities in rural areas.

Currently, Dr Tesfuhuney is expanding his research on underutilised crops in the region, focusing on how these crops can help smallholder farmers adapt to the impacts of climate change while improving nutritional security.

Work on the right track

Dr Calvin D. Ullrich, Senior Lecturer in Interdisciplinary Theology: Historical and Constructive Theology, who obtained a Y1 rating, says though there is much talk in South African academia about the necessity of an NRF rating which is not always positive (at least in the broader humanities), the NRF does have its strengths.

“I think it pushes one to critically consider one’s work as a whole; to reflect on its current shape and to identify lacuna within a broader trajectory. There is something generative about this process in and of itself. Feelings of relief but also of affirmation then: a rigorous peer-review system which acts as a metric, according to which one might be able to say, ‘my work is somehow on the right track’ — I think there is certainly value in that.”

According to Dr Ullrich, pursuing your research and making critical interventions into your field, means the rating can follow as a necessary consequence. Research for him, he continues, like most academics, is deeply personal and exhilarating, and so acquiring the rating can also be seen as just another internal aspect of the research process as opposed to being contingent to it.

He has several research projects currently in the research pipeline including smaller writing projects relating to eco-phenomenology and eco-theology and political theology in South Africa. A larger project, scheduled to begin later next year and continuing for the next three years (2025-2028), involves a more intense investigation of the social dimensions of ‘affects’ and how this could be deployed within the specific social context of faith communities.

It’s humbling

For Prof Matildie Wium, Associate Professor in the Odeion School of Music, her first C2 rating is not only an honour for her contribution to her field, but also a humbling moment, because the experience of applying for a rating makes clear how much room remains for growth.

Her research has two main focus areas: (a) 20th-century South African art music, studied from an analytical-hermeneutic perspective, and (b) the musical practices and experiences of mid-19th-century female opera singers in London, studied by means of archival documents.

“I am currently working on converting conference papers I had delivered recently into articles, mainly on the South African art music side of my endeavours. There are papers about Mimi Coertse (in collaboration with my colleague Dr Albertus Engelbrecht), Hubert du Plessis’s Opus 24 (in collaboration with my past student Dr Melissa Gerber), and Michael Mosoeu Moerane’s tone poem Fatshe la Heso under development.

“I am also co-writing a paper analysing some items from ethnomusicologist Gerhard Kubik’s archive of Àló (Yoruba storytelling) with my colleague Dr Joseph Kunnuji,” says Prof Wium.

Dedication, resilience, and strategic focus

Dr Andronicus Akinyelu, Lecturer in the Department of Computer Science and Informatics, called his first Y2 rating incredibly rewarding as it reaffirms his hard work and perseverance have not been in vain. “It also serves as a great source of motivation for me to continue pushing boundaries and striving for excellence in my academic and research pursuits. I am deeply grateful to God for this achievement. I am delighted to have been successful. It is an important milestone in my academic journey,” he says.

According to him, achieving an NRF rating requires a combination of dedication, resilience, and strategic focus. It involves publishing high-quality research in top-tier journals, supervising postgraduate students, and contributing significantly as a first or corresponding author on various projects.

“My research spans multiple cutting-edge areas, including machine learning, deep learning, computer vision, medical diagnosis, sustainable agriculture, and responsible artificial intelligence (AI). Currently, I’m collaborating with international researchers to develop deep-learning techniques that predict treatment responses in cancer patients.

“This research has the potential to significantly advance personalised medicine by enabling more accurate and timely interventions. Additionally, I am deeply committed to promoting responsible AI by developing frameworks and models that prioritise ethics in AI systems,” says Dr Akinyelu.

Prof Vasu Reddy, Deputy Vice-Chancellor of Research and Internationalisation says: “Congratulations to all our newly rated researchers. We are expecting more in the coming months as the results of applications slowly filter in. We are extremely proud of our rated researchers for the recognition they have received. This is in large part the result of their contribution to producing high-quality research. There are many benefits that accrue to our researchers who are rated, namely an investment in their scholarship, including UFS support, as well as opportunities to further enhance their academic trajectory.”

Nanoscience, which is revealing new properties of very small arrangements of atoms, called nanoparticles, is opening a new world of possibilities. The Department of Physics at the University of the Free State is undertaking fundamental research with potential commercial applications. Its equipment and expertise is giving solid state physics research the edge in South Africa.

The UFS team of researchers and students are passionate about studying planets and atoms, all under one roof. Recently, the department, in collaboration with the South African Agency for Science and Technology Advancement (SAASTA), hosted a nanotechnology facility tour to give the public, learners and the media the opportunity to familiarise themselves with the science of nanotechnology, its origins, potential applications and risks.

Successes of the department
According to Prof Hendrik Swart, Senior Professor in the Department of Physics, the increase in resources since 2008 is playing a big role in the success rate of its research outputs. The Sarchi Chair awarded to Prof Swart in 2012 (bringing with it funding for equipment and bursaries) also contributed to the successes in the department.

The UFS Directorate Research Development also availed funding that was used for bursaries. These bursaries made it possible for the department to appoint 10 post-doctoral fellows, not one of them originally from South Africa.

The investment in people and equipment resulted in researchers and students publishing some 80 articles in 2016. Their work was also cited more than 900 times by other researchers in that year.

Another highlight in terms of the department’s growth in the past 10 years is the new wing of the Physics Building. Physics at the UFS is the only place in sub-Saharan Africa where state-of-the art equipment is found under one roof.

Application of research
The department is a unique research facility with equipment that includes the X-ray Photoelectron Spectrometer (for the study of atoms), the Scanning Auger Microscope, as well as the Ion Time-of-Flight Secondary Ion Mass Spectrometer (revealing the chemical bonds in a sample, and drawing maps of the positions of atoms).

One of the areas on which the department is focusing its research, is phosphors. Researchers are exploring light emitting diodes (LEDs) which use less energy, are brighter and provide a wider viewing field. They are also looking into LED displays (LCDs) which are used in flat screens – the phosphors create the different colours and backlighting.

The research on solar cells reveals that phosphors can increase their efficiency by increasing the range of light frequencies which can be converted into electricity. Glow-in-the-dark coatings absorb light in the day and emit it later so cells can charge at night. As glow-in-the-dark phosphors become cheaper and more effective, they can be used as a lighting substitute on the walls of houses, street numbers and stop signs.
