Renata van Reenen
Renata van Reenen has been a South African Sign Language (SASL) champion since primary school, and she is using her postgraduate degree to further SASL in higher education.

Renata van Reenen, a master’s student at the University of the Free State (UFS), recalls how a school talk in 1998 by Deaf activist Johan Gouws instilled in her a kind of ‘duty’ to become a champion for Deaf people. Van Reenen, who in 1987 became the first Deaf child in South Africa to receive a cochlear implant, says it was at this talk that she realised that, as a Deaf person, she has her own language, identity, and culture – and that she is not “a person with a disability”. 

Van Reenen is currently a language facilitator in the UFS Department of South African Sign Language (SASL) and Deaf Studies, and she believes that Deaf students should be empowered to embrace their attributes. Her interests include exploring different sign languages around the world, Deaf issues, and how Deaf children are supported in schools for the Deaf. “One of my hobbies is to put my creative ideas on paper, and I would like to develop and record these stories in SASL so they can be accessible to Deaf schools as resource materials,” she says. “These materials would then also be accessible when teaching the subject South African Sign Language as a Home Language.”

Van Reenen, who worked as an assistant teacher at a school for the Deaf for seven years, is passionate about SASL and the lived experiences of the Deaf. We asked her to share some views on empowering the Deaf and SASL: 

Why is it important to empower Deaf students?

When I was 17, I had no Deaf identity. I did not understand sign language and how it was used – when the Deaf person gave a speech at the school, it changed my life. I realised that I am a Deaf person with my own language, identity, and culture, and that I am not a person with a disability. I strongly believe that Deaf students need to be empowered to fully embrace their identity, language, and culture, and through this expectance show the world who we are. My favourite motto I always share with my Deaf learners is: “Believe in yourself, show them what you can do.” I also encourage them to continuously teach Hearing students the beautiful language, as the famous Deaf quote states: “Sign language is the noblest gift God has given to Deaf people.” George Veditz, the former president of the National Association of the Deaf of the United States, said, “As long as we have Deaf people on Earth, we will have signs.” He protected our language at a time (the early 20th century) when the world strongly believed that Deaf people had to learn through oralism and had to learn spoken language in order to function as a “normal person” alongside hearing people.

As a Deaf person, do you believe the UFS community is doing enough to accommodate you, and how do you feel about being part of the Department of SASL and Deaf Studies? 

When I received a link for a workshop I had to attend, I was so overwhelmed when I saw the interpreter on the video link, and knew that it would be extremely helpful for me during my research. The UFS Centre for Universal Access and Disability Support made sure I have full access to any workshops the university provides. It is amazing that my supervisor can also sign. That made me feel at home, being in a Deaf world without communication barriers. The department is an amazing team that supports and encourages me during my studies.

What will you be doing in honour of Deaf Awareness Month?

The SASL Department and I, along with Deaf Studies, have organised a “Signing Space” event in September to bring Deaf and Hearing students together to socialise with each other. This event will give Hearing students the opportunity to learn about the Deaf world. During this event I will give a small presentation such as “Poetry in SASL” that will show that Deaf people have their own literature, and that it forms part of their language, SASL. We will not only focus on presentations but also on fun activities, such as games that are prominent within the Deaf community. 

Why did you decide to pursue your MA at the UFS? 

During the coronavirus pandemic I applied to the University of Gallaudet in Washington, DC to study for a Master of Education in Sign Language degree. Gallaudet is the world's only university in which all programmes and services are specifically designed to accommodate deaf and hard of hearing students. I was accepted to study further and to ultimately become a teacher or lecturer. My aim was to train Deaf adults to qualify in different areas of SASL, ranging from SASL Linguistics, SASL Pedagogy, SASL Media Production, and so forth. In an ideal world these could be offered as short courses through some tertiary institutions which already offer SASL on undergraduate and postgraduate levels. Unfortunately, I did not have enough support, but I did not let it stop my dream. I decided to change my university of choice and applied at the University of the Free State. I am pursuing my MA degree and continuing my studies as a Deaf person. The University of the Free State is providing and recognising SASL. This is a positive step, as South African Sign Language will soon be the twelfth official language of South Africa.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
