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 Her research focuses on challenging outdated systems and empowering individuals through innovative, practical technology.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

Mushrooms have so many medicinal applications that humans have a substance in hand to promote long healthy lives. And it is not only humans who benefit from these macrofungi growing mostly in dark spaces.

“The substrate applied for growing the mushrooms can be used as animal fodder. Keeping all the medicinal values intact, these are transferred to feed goats as a supplement to their daily diet,” said Prof Bennie Viljoen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Curiosity and a humble start
“The entire mushroom project started two years ago as a sideline of curiosity to grow edible gourmet mushrooms for my own consumption. I was also intrigued by a friend who ate these mushrooms in their dried form to support his immune system, claiming he never gets sick. The sideline quickly changed when we discovered the interesting world of mushrooms and postgraduate students became involved.

“Since these humble beginnings we have rapidly expanded with the financial help of the Technology Transfer Office to a small enterprise with zero waste,” said Prof Viljoen. The research group also has many collaborators in the industry with full support from a nutraceutical company, an animal feed company and a mushroom growers’ association.

Prof Viljoen and his team’s mushroom research has various aspects.

Growing the tastiest edible mushrooms possible
“We are growing gourmet mushrooms on agricultural waste under controlled environmental conditions to achieve the tastiest edible mushrooms possible. This group of mushrooms is comprised of the King, Pink, Golden, Grey, Blue and Brown Oysters. Other than the research results we have obtained, this part is mainly governed by the postgraduate students running it as a business with the intention to share in the profit from excess mushrooms because they lack research bursaries. The mushrooms are sold to restaurants and food markets at weekends,” said Prof Viljoen.

Natural alternative for the treatment of various ailments
“The second entity of research encompasses the growth and application of medicinal mushrooms. Throughout history, mushrooms have been used as a natural alternative for the treatment of various ailments. Nowadays, macrofungi are known to be a source of bioactive compounds of medicinal value. These include prevention or alleviation of heart disease, inhibition of platelet aggregation, reduction of blood glucose levels, reduction of blood cholesterol and the prevention or alleviation of infections caused by bacterial, viral, fungal and parasitic pathogens. All of these properties can be enjoyed by capsulation of liquid concentrates or dried powdered mushrooms, as we recently confirmed by trial efforts which are defined as mushroom nutriceuticals,” he said.

Their research focuses on six different medicinal genera, each with specific medicinal attributes:
1.    Maitake: the most dominant property exhibited by this specific mushroom is the reduction of blood pressure as well as cholesterol. Other medicinal properties include anticancer, antidiabetic and immunomodulating while it may also improve the health of HIV patients.
2.    The Turkey Tail mushroom is known for its activity against various tumours and viruses as well as its antioxidant properties.
3.    Shiitake mushrooms have antioxidant properties and are capable of lowering blood serum cholesterol (BSC). The mushroom produces a water-soluble polysaccharide, lentinan, considered to be responsible for anticancer, antimicrobial and antitumour properties.
4.    The Grey Oyster mushroom has medicinal properties such as anticholesterol, antidiabetic, antimicrobial, antioxidant, antitumour and immunomodulatory properties.
5.    Recently there has been an increased interest in the Lion’s Mane mushroom which contains nerve growth factors (NGF) and may be applied as a possible treatment of Alzheimer’s disease as this compound seems to have the ability to re-grow and rebuild myelin by stimulating neurons.
6.    Reishi mushrooms are considered to be the mushrooms with the most medicinal properties due to their enhancing health effects such as treatment of cancer, as well as increasing longevity, resistance and recovery from diseases.

Valuable entity for the agricultural sector
Another research focus is the bio-mushroom application phenome, to break down trees growing as encroaching plants. This research is potentially very valuable for the agricultural sector in the areas where Acacia is an encroaching problem. With this process, waste products are upgraded to a usable state. “It is therefore, possible to convert woody biomass with a low digestibility and limited availability of nutrients into high-quality animal fodder. By carefully selecting the right combination of fungus species to ferment agro-wastes, a whole host of advantages could become inherently part of the substrate. Mushrooms could become a biotechnological tool used to ‘inject’ the substrate that will be fed to animals with nutrition and/or medicine as the need and situation dictates,” said Prof Viljoen.
