The recently dual-capped Stefanus Scheepers, Senior Admin Assistant Officer in the UFS Faculty of Education, says his success lies in mastering the art of balance.

Completing a master’s degree in record time is a remarkable achievement, but for Stefanus Scheepers, Senior Admin Assistant Officer at the University of the Free State Faculty of Education, it marked the beginning of an even more extraordinary academic journey. In a feat few could match, he earned two master’s degrees in just 20 months.

Scheepers’ first degree, a Master of Education specialising in Higher Education Studies, was conferred by the University of the Free State (UFS) on 9 December 2024. His thesis, ‘Effective Pedagogical Practices Teaching Assistants Use in Hybrid Teaching Modes: A Community of Inquiry Approach’, explored innovative teaching strategies in hybrid learning environments.

The second degree, a Master of Science by Research in Sustainable African Futures, was conferred through the Wits-Edinburgh Sustainable African Futures (WESAF) Doctoral Programme. His thesis, ‘Investigating the Perception, Adoption, and Utilization of Generative Artificial Intelligence in South African Higher Education Institutions’, examined the impact of generative artificial intelligence (GAI) on sustainable education in South Africa.

“My experience presenting workshops on GAI tools and its misuse by students sparked my research interest,” he explained. The resulting mini-dissertation shed light on the critical need for sustainable education practices in an era increasingly influenced by AI. This theme will continue as Scheepers embarks on a PhD at Wits University in 2025, exploring how to balance GAI’s benefits and risks in education.

Initially, Scheepers embarked on a part-time master’s degree in 2023 at the UFS while working full-time. “I hadn’t planned to complete two degrees,” he said, “but my supervisor’s encouragement and excellent guidance made completing the degree within a year seem possible.” Midway through, however, a nomination from the Dean and Vice-Dean of the Faculty of Education changed everything. The WESAF Doctoral Programme offered an opportunity that was too valuable to pass up, even though it added another degree to his demanding schedule.

“At first I was very hesitant, but my supervisor said that I would regret not taking it”, he said with a smile.

Time management does the trick

Balancing the demands of studying for two master’s degrees was no small feat. Scheepers chose to embrace meticulous time management, creating a schedule that integrated study and rest.

“Time management is not just about making a plan but sticking to it,” he emphasised. This structured approach allowed him to maximise productivity without burnout. “I must admit, working at night in your office did feel strange at first, but tranquil after a while.” Weekends included much-needed downtime, which helped him maintain resilience throughout.

Reflecting on this intense period, Scheepers attributes his success to cumulative skills gained over the years. “Every skill learnt in prior degrees was put to the test. The journey wasn’t easy, but intentionally applying these skills made the challenge rewarding.”

After nearly six years at higher education institutions – Scheepers’ career ambition is to transition into a lecturer role, with the hope of passing on his research and hands-on experience to a new generation of students.

When asked what he would share with prospective students at the UFS, Scheepers said, “The path to success isn’t always straightforward. I’ve experienced setbacks, even dropping out twice before finding my footing. But each challenge taught me resilience and determination. To all students: Keep going, even when the journey feels daunting. Every obstacle you overcome is a step closer to your goals. Remember, success is not about avoiding failure but learning and growing stronger with each experience. Stay focused, believe in yourself, and trust the process – you can do much more than you may realise.”

This remarkable dual graduation is not only a rare achievement in academia but also highlights Scheepers’ exceptional time management, strategic planning, and unwavering commitment to advancing the fields of education and sustainable futures.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
