Health Sciences Medal winners
Three of the Dean’s medal winners: Celine Taute, Angelique Johnson and Dr Monique Davidson after the graduation ceremony.

It was a big week for the newest University of the Free State (UFS) graduate, Angelique Johnson, who not only graduated with a Bachelor of Medical Science Honours in Pharmacology degree with distinction, but she was also awarded the Dean’s medal in the Faculty of Health Sciences at the university’s April graduation ceremonies.

Only a day before crossing the graduation stage on Friday 11 April, Angelique was also awarded the UFS Faculty of Health Sciences floating trophy for achieving the best results in respect of a bachelor honours degree in the faculty. 

“It’s honestly an honour. Receiving the Dean’s Medal feels surreal — it’s a reminder that the effort I put in didn’t go unnoticed. It’s also motivating and makes me feel proud to represent my faculty in such a positive way.

“Graduating with distinction feels incredibly rewarding — it’s a validation of all the late nights, hard work, and perseverance. Achieving this required discipline, time management, and a genuine passion for the material. I also leaned on a strong support system and made sure to stay consistent throughout the academic year,” says Angelique.

 

Dean’s Medal winners

The Dean’s medal was also awarded to Celine Taute, Alexander van Wyk and Dr Monique Davidson who all graduated last year. Taute, who graduated with a Bachelor of Medical Science with specialisation in Radiation Sciences degree (obtained with distinction), was awarded the Dean’s medal for achieving the best results as a third-year student. Van Wyk graduated with Bachelor of Biokinetics degree with distinction and received the Dean’s medal for achieving the best results as a fourth-year student while Dr Davidson received was awarded for obtaining the best results as a fifth-year student. 

Dr Davidson graduated with the degree Bachelor of Medicine and Bachelor of Surgery with distinction. Just like Johnson, Dr Davidson, Taute and Van Wyk was also awarded the faculty’s floating trophy for achieving the best results in their respective study years at Thursday’s (10 April 2025) prize-giving ceremony. 

 

Driven by passion 

According to Angelique, she will now pursue an MBChB degree as her passion for medicine drives her to go beyond simply making small changes — she wants to create a meaningful, lasting impact. “To borrow and adapt the words of Prof Gert van Zyl, Dean of the Faculty of Health Sciences, I don’t just aim to create ripples or waves in the field of healthcare — I aspire to create a tsunami of positive change in people’s lives and in the medical profession.”

In 2023 she completed a BSc in Human Physiology (cum laude) from the University of Pretoria (UP). She decided to enrol for an Honours in Pharmacology degree after developing a strong interest in how the body responds to different substances, especially at the cellular and molecular levels.

“Pharmacology felt like a natural extension of that curiosity — it dives deeper into the mechanisms of drug action and how they can be used to treat disease. I wanted to better understand how physiological processes can be manipulated for therapeutic benefit, and pharmacology offered the perfect balance between science and real-world medical application,” she concludes.

 

Provide comfort 

According to Celine, both the Dean’s medal as well as the awards came as a big surprise because she did not set out to achieve them. “I feel immensely blessed and thankful. Things that are worth it, require some sacrifices.” 

“I am so grateful. I set out to do my best and trusted that God would sort out the details. Discipline and hard work were key in my success. A person is not an island, so having family that always believed in me even when I didn't, helped me get through those tough exams,” says Celine. 

Celine, who is currently busy with an honour’s degree whereafter she will embark on a two-year internship, says she chose to specialise in radiation as she wanted to provide comfort and education to the mostly cancer patients and their families who radiation treatment can help.

Carbon dioxide makes for more aromatic decaffeinated coffee

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
