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 Her research focuses on challenging outdated systems and empowering individuals through innovative, practical technology.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.”

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.
