NAS Medal Winners
The four medal winners from the Faculty of Natural and Agricultural Sciences are from left: Christine Rossouw, Philippus Kotzé, Michail Cloete, and Jocelyne Smith.

At the University of the Free State (UFS) April graduation ceremonies, the Faculty of Natural and Agricultural Sciences proudly celebrated the success of 1484 graduates – each one marking a milestone of academic excellence. Among these achievements, four standout students were awarded top honours for their exceptional academic performance.

Jocelyne Smith graduated with a Bachelor of Science Honours in Data Science and received both the prestigious Senate Medal - awarded for the highest weighted average across all UFS faculties - and the Dean’s Medal for achieving the top results in a bachelor honours degree within the faculty. 

Joining her in academic distinction were Christine Rossouw, Philippus Kotzé, and Michail Cloete, who each received a Dean’s Medal for outstanding results in their respective qualifications. Rossouw earned top marks in a three-year bachelor's degree, Kotzé in a four-year bachelor's degree, and Cloete for a master’s degree.

 

From setbacks to success: Jocelyne Smith’s unexpected path to excellence

Jocelyne Smith never intended to pursue Data Science. Her dream was to study medicine and make a meaningful difference in her community. However, when things did not go as planned, she found herself at a difficult crossroads. “I was devastated and unsure what to do next,” she recalls. 

A timely suggestion from Prof Eduan Kotzé introduced her to Data Science – a field she had never considered but soon came to love. Now pursuing a master’s degree, Smith says receiving the Senate and Dean’s Medals was a complete surprise. “I just tried to do my best every day,” she says. “Receiving the medals is a reminder that even when life takes an unexpected turn, the destination can still be extraordinary.”

Her journey has been one of perseverance, long nights of study, and a commitment to community and helping others understand complex material. “Helping others deepened my own understanding and made the experience more meaningful,” she adds. 

Looking ahead, Smith aims to harness Artificial Intelligence (AI) to revolutionise education in South Africa. “AI can make a real difference if used correctly - especially in education,” she explains. Her research focuses on challenging outdated systems and empowering individuals through innovative, practical technology.

 

Designing for impact: Michail Cloete’s award-winning architectural journey

For Michail Cloete, architecture is not just about buildings – it is about problem-solving and creating meaningful spaces. Inspired by his father’s work, he pursued architecture with clarity of purpose and deep-rooted passion.

“My academic success was driven by balance, consistency, and a genuine passion for impactful design,” he says. That mindset paid off, earning him the Dean’s Medal for best performance in a master’s degree.

Cloete views the medal not only as personal recognition but also as a tribute to those who supported him. “It reflects the collective effort – the love, support, and sacrifices of my family and friends,” he shares. 

Looking forward, Cloete hopes to join an architectural firm that creates spaces with lasting impact, continuing a journey grounded in creativity, commitment, and thoughtful design.

 

Rooted in passion: Philippus Kotzé recognised for academic excellence

A deep love for farming and a growing interest in agriculture led Philippus Kotzé to pursue a degree in Animal Sciences. His approach to his studies was straightforward: “I went into the course to learn as much as I could. Good marks were just a welcome side-effect.”

Kotzé’s self-discipline, coupled with encouragement of classmates and lecturers, helped him navigate the demands of a four-year degree – resulting in the Dean’s Medal for academic excellence. 

“There is a saying, ‘Vele hande maak ligte werk.’ For us, the lights were on for four straight years,” he jokes, crediting the collective effort of his support network for his success. 

Now farming full-time, Kotzé aims to grow and diversify within the agricultural sector – bringing the same focused dedication to his career that defined his academic journey. 

 

Bright minds, bold dreams: Christine Rossouw shines in science

Driven by a love for problem-solving and a fascination with how things work, Christine Rossouw found her perfect fit in the sciences. “I love experimenting and figuring things out,” she says. Her curiosity and determination helped her achieve top marks in a Bachelor of Science degree specialising in Chemistry and Physics, earning her the Dean’s Medal for the best results in a three-year bachelor’s degree.  

Rossouw credits her success to maintaining a healthy balance. “Work hard, stay curious, and make time to recharge,” she advises. For her academic achievement is just the beginning - a stepping stone toward big ambitions, that include designing fireworks, advancing green energy, and improving plastic recycling.

Although the full weight of the award is still sinking in, Rossouw is already looking to the future – one that promises to be as bright as her ideas.

 

Words of wisdom: Emmie Pietersen’s message to graduates 

Emmie Pietersen, Head of Strategy and Programme Development at Peritum Agri Institute, delivered a heartfelt message to graduates at all three sessions on Thursday, 10 April. Drawing from the lessons that continue to shape her own life, she urged graduates to embrace each day as a gift – a reminder that every moment presents both a chance and a choice. 

“Your presence is your brand,” she said, encouraging graduates to carry themselves with both confidence and humility. True success, she explained, lies in the ability to prioritise, to plan with intention, foster meaningful partnerships, and persevere - because failure only happens when we stop trying.

In closing, she shared a powerful message she once gave to her son: “You were fearfully and wonderfully made. Grow your career with courage, but tread softly. Make us Kovsies proud.”

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
