Prof Tomas Vetrik, Professor in the Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), recently delivered his inaugural lecture on the Bloemfontein Campus.

His research area is graph theory, and he mainly focuses on the degree-diameter problem, graph indices, and metric dimension of graphs.

Research focus

According to Prof Vetrik, mathematics was always his favourite subject in school. He also excelled in maths at university and decided to enrol for a course on graph theory while working on his master’s degree. “I liked it, so I also chose topics from graph theory for my PhD thesis,” he says.

In 2014, at the age of 32, he was appointed Associate Professor at the UFS, after postdoctoral research at the University of KwaZulu-Natal and working at the University of Pretoria. An NRF-rated researcher, he has published close to 75 research papers, a third of that as a single author in some of the most well-known journals in his area. Moreover, he was also research supervisor of three PhD and three master’s students.

International collaborations

In the eight years since his appointment at the UFS, Prof Vetrik has made research visits to universities from 14 different countries that have invited him for research collaborations. 

“I am often overseas. I like working from different places. It is interesting to me, and it helps me to be productive,” says Prof Vetrik, explaining some of the inspiration behind his mathematical ideas.

In the next two years, he would like to study more general mathematical problems beyond his current research area.

He says he is addicted to his research. “It overshadows all my other interests.” 

On the rare occasion when he is not working on his research, Prof Vetrik states that he has to keep himself busy. Unable to relax and do nothing, he likes to do sports of some kind or to travel. 

“I am a simple person. I do not even have a TV at home. I use an old-fashioned mobile phone that cannot access the internet,” he says.

Eugene de Kock, FW de Klerk and forgiveness – Prof Gobodo-Madikizela’s take on gestures of reconciliation
2015-02-06

What Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness and Reconciliation Studies at the University of the Free State, found over the years talking to Eugene de Kock, was a man tortured by his past. By the deeds he has committed.

“As a result he was confronting these – not as a cog in a machine – but as a person who actually did the deed himself,” Prof Gobodo-Madikizela said during an interview [https://soundcloud.com/primediabroadcasting/dr-gobodo-on-de-kock-parole] with Pippa Hudson on Cape Talk. A man taking personal responsibility.

Against the backdrop of De Kock recently granted parole, what, then, is the nature of forgiveness?

“Often people think when they forgive, you forgive and forget. That’s not the point,” Prof Gobodo-Madikizela says. “Forgiving, in fact, I found is the wrong word. We are using forgiveness for a range of responses. What I find useful in this kind of work is to think about how people change, how people are transformed. In other words, to think about our empathic connection to people who are our former enemies.” In other words: to reach a place where both parties can see each other as fellow human beings. “Somehow when a person expresses remorse – in the way Eugene de Kock has done – it opens a door for the different kinds of relationships to that traumatic past,” Prof Gobodo-Madikizela says.

In an article for the Sunday Times, Prof Gobodo-Madikizela refers to the motion to immortalise F W de Klerk by renaming Table Bay Boulevard after him. In this piece, she clearly points out that De Klerk is not without blood on his hands. She agrees with Mayor Patricia de Lille’s support of this tribute to De Klerk, though, when De Lille refers to ‘the spirit of reconciliation that Tata Madiba believed in’.

Justice Minister Michael Masutha – who granted De Kock parole – and De Lille “are right in evoking the memory of Nelson Mandela through these important gestures of reconciliation,” Prof Gobodo-Madikizela remarks. The need to return to Nelson Mandela’s vision, she adds, remains urgent.
