Gali Mokgosi
Gali Mokgosi uses her passion for students and films to promote conversations about mental health and how campus life inside and outside the classroom – including residence life – affects and is affected by the physical, mental, and spiritual health of its students.

Using her experience in theatre and her passion for students, Gali Mokgosi, Residence Head of House Madelief, helps students explore and implement skills to cope with the demands of university life. A Health and Wellness coordinator for residence life, she helps improve their lives by teaching them the value of sufficient sleep, nutrition, exercise, recreation, positive coping strategies, healthy social and sexual relationships, and a sense of belonging within residences.

Mentoring and supporting university students

As a former English lecturer for first-year students, this go-getter saw an urgency to mentor and support university students. In 2016, she landed a job as residence head and resigned from lecturing to focus on theatre and residence affairs. Soon after her appointment, she and her colleague, Nthabiseng Mokhethi, Residence Head of House Ardour, were asked to coordinate the Residence Life Health and Wellness portfolio at a time when there were many suicide attempts and mental health issues, and drug and alcohol abuse plagued residences.

“Our main responsibility as Health and Wellness coordinators is to support Residence Committee Health and Wellness representatives (RCHW) in their respective residences. We facilitate training for RCHW peers and help them to think broadly about how campus life inside and outside the classroom – including residence life – affects and is affected by the physical, mental, and spiritual health of its students.”

Using film to address topical issues

With an honours degree in Drama and Theatre Arts, this UFS alumna knew she had to adapt to virtual means for her portfolio to continue supporting students during COVID-19.

“There was a need for intervention, and I saw an opportunity to close this gap by helping students through their challenges using films. I wrote films that directly address the challenges students were/are facing. Being a residence head, content for my films is always under my nose, and the storyline is undeniably relevant to them.”

Mokgosi wrote and produced four films for the various student support offices, with the help of Shibashiba Moabelo, Institutional HIV/AIDS Programme Coordinator at Kovsie Health, and Pulane Malefane, Assistant Director: Residence Life. These films are, I am, Triggers, Versus me, and Monate jou lekker ding.

This scriptwriter says when students can identify themselves in a story, they tend to gravitate towards a solution as suggested by the story. Students across the University of the Free State’s (UFS) three campuses act in the films. After watching a film, students engage with each other and receive tools to explore the story and reflect on the outcomes as suggested by the film.

Proving her sensitivity for inclusiveness, she had an opportunity to be part of the art skills exchange programme in Deaf theatre at Gallaudet University, Washington, DC. She also presented a research paper in Athens, Greece.

Mokgosi is looking forward to experiment with Deaf films in 2023.

Asked how she looks after her mental health, she reveals: “I take care of my mental health through prayer and meditation. I believe the first place to prosper is through my spiritual life. God is my strength from day to day. He is my all in all. Without Him, I will fall.”

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.
