Edwin Skhosana
Edwin Skhosana is working hard to become a successful and competent actuary one day. With him is his lecturer, Dr Michael von Maltitz.

Edwin Skhosana, an Actuarial Sciences student, was described by his lecturer, Dr Michael von Maltitz of the Department of Mathematical Statistics and Actuarial Science, as ‘very quiet’ in his Causal Inference class. 

This may sound like a compliment, but it’s not.

For Dr Von Maltitz, being quiet is definitely not encouraged – not with the new teaching methods applied in class.

“See, my class is all about engagement – getting the students to watch videos on the topics, read about the methods in question, and then come to class to grill me about things they don’t understand. This change in teaching method is extremely disconcerting for many Mathematical students, who have up until now only been taught in the ‘memorise-regurgitate’ form they had ever since the start of high school,” he explains.

Future success


“My goal is to get the students to a level of understanding where they can sit down with me or with an expert in the field and have a conversation about the Mathematical Statistics topics that I teach. This is a very difficult task in such a technical module, and few students ever feel comfortable enough to engage with me actively in class in this way,” Dr Von Maltitz points out. 

Edwin is working hard towards applying the skills and knowledge he has obtained at university to become a successful and competent actuary one day. 

An important turning point was when it dawned on him how the things discussed in class could find an important practical application in so many fields.  

“This suddenly drove a spontaneous fascination in my mind that led me to engage with Dr Von Maltitz,” the previously quiet Edwin explains.

And everything changed.

Desperate to learn

Dr Von Maltitz explains: “Edwin came to my office to ask some questions. The incredible thing was that he sat down, and a conversation about the Mathematics, the foundations, and the methods just flowed between us. I have seldom had such an insightful chat about my module with a student. It was like a cascade of information just fell into place for Edwin.”

Although he sometimes still experiences his studies as challenging and grapples to adapt to the various styles of lecturing from different lecturers, Edwin now has hope for his class in Causal Inference. 

“I think Dr Von Maltitz’s way of presenting in class is excellent. It is, however, hard to grasp if you are still anchored in the old way of cramming, because he wants you to understand and be able to apply what he teaches,” says Edwin.

“It was just wonderfully refreshing to see someone so desperate to learn something (rather than just wanting to get a degree), and then actually managing to turn around a bad semester mark into such a river of understanding,” Dr Von Maltitz concludes.

Names are not enough: a molecular-based information system is the answer

South Africa is the second-largest exporter of citrus in the world, producing 60% of all citrus grown in the Southern Hemisphere. It exports more than 70 % of its citrus crop to the European Union and USA. Not being able to manage fungal pathogens effectively can have a serious impact on the global trade in not only citrus but also other food and fibre crops, such as bananas, coffee, and cacao.

The Department of Plant Sciences at the University of the Free State (UFS) hosted a public lecture by Prof Pedro W. Crous entitled “Fungal Pathogens Impact Trade in Food and Fibre: The Need to Move Beyond Linnaeus” on the Bloemfontein Campus.

Prof Crous is Director of the world’s largest fungal Biological Resource Centre, the Centraalbureau voor Schimmelcultures (CBS), in the Netherlands. He is also one of the top mycologists in the world.

Since the topic of his lecture was very pertinent to food security and food safety worldwide, it was co-hosted by the Collaborative Consortium for Broadening the Food Base, a multi-institutional research programme managed by Prof Wijnand Swart in the Department of Plant Sciences.

Reconsider the manner in which pathogens are identified

Prof Crous stressed that, because international trade in products from agricultural crops will expand, the introduction of fungal pathogens to new regions will increase. “There is therefore an urgent need to reconsider the manner in which these pathogens are identified and treated,” he said.

According to Prof Crous, the older Linnaean system for naming living organisms cannot deal with future trade-related challenges involving pests and pathogens. A system, able to identify fungi based on their DNA and genetic coding, will equip scientists with the knowledge to know what they are dealing with, and whether it is a friendly or harmful fungus.

Embrace the molecular-based information system

Prof Crous said that, as a consequence, scientists must embrace new technologies, such as the molecular-based information system for fungi, in order to provide the required knowledge.

He presented this very exciting system which will govern the manner in which fungal pathogens linked to world trade are described. This system ensures that people from different countries will know with which pathogen they are dealing. Further, it will assist with the management of pathogens, ensuring that harmful pathogens do not spread from one country to another.

More about Prof Pedro Crous


Prof Crous is an Affiliated Professor at six international universities, including the UFS, where he is associated with the Department of Plant Sciences. He has initiated several major activities to facilitate global research on fungal biodiversity, and has published more than 600 scientific papers, many in high impact journals, and authored or edited more than 20 books.
