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 Her research focuses on challenging outdated systems and empowering individuals through innovative, practical technology.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

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
