Dr Yolandi Swart
Dr Yolandi Swart, who took over from Prof Lynette van der Merwe as the new Director of the Undergraduate Medical Programme (MB ChB programme) in the School of Clinical Medicine within the Faculty of Health Sciences at the University of the Free State (UFS), says she is excited about the new opportunities that come with this position.

The new Director of the Undergraduate Medical Programme (MB ChB programme) in the School of Clinical Medicine within the Faculty of Health Sciences at the University of the Free State (UFS) has a passion for teaching and learning and brings a wealth of experience with her.

Dr Yolandi Swart, who took over from Prof Lynette van der Merwe on 1 March 2022, says she is excited about the new opportunities that this position brings. She was not actively job-hunting and came across the advertisement by accident but was thrilled when she was informed that she is the recommended candidate.

A deep love for the UFS

“I will be heading up an amazing team of people who drive the MB ChB programme, making sure that we walk with our students on their journey to become the next generation of health professionals who will contribute to the health and wellness of our population. Our functions include coordinating the undergraduate curriculum, providing student support, as well as logistic support to ensure the smooth running of the MB ChB programme,” says Dr Swart.

As an alumna of the university (she obtained both her MB ChB and postgraduate MMed in Community Health at the UFS), she has a deep love for the UFS, as it has played a huge role in developing her into the person she is today.

According to Dr Swart, she looks forward to getting to know the students and seeing them develop into the best they can be, as well as engaging with the academic staff as they guide and train the students. She brings a diverse background to the position, having practised as a doctor, specialised in Community Health, and worked in clinical research at various levels, including senior management. This has afforded her the opportunity to equip herself with skills that she hopes will provide support and direction to the Undergraduate Programme Management team in order to provide excellent service in all its functions.

Her vision

“I love teaching and learning – taking a concept and making it accessible to someone.  There are few things as satisfying as seeing that expression that says ‘Oh, now I get it!’

Kovsies has always had a reputation of producing excellent doctors.  “It is my vision to build on that reputation, integrating local and international best practices as they develop into our students’ training, with the aim of developing young professionals who are competent, resilient, and able to face the challenges that life will throw at them – so that they, in turn, can play their role to influence lives for the better.”

Prior to her appointment, she worked at FARMOVS as a clinical research physician for more than six years, the past year and a half as the company’s Medical Director. Says Dr Swart: “I love challenging myself with new things every so often. Past and present hobbies include surfing (which died an early death, as I was horrible at it), scuba diving (yes, with sharks as well), horse-riding, and self-defence.  Most recently, I got hooked on traditional archery – a very challenging skill to try and master.”

Dr Swart says she has learned throughout her personal life and professional career that life sometimes takes unexpected turns – but if one is open to the opportunities afforded by those unexpected turns, it often turns out so much better than the original plan could ever have been. “Difficulties and challenges will always come – but if one faces them with a positive attitude, they teach life skills that you would otherwise never have attained.”

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.
