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.

“It is quite easy to write a book in a professional capacity but very difficult to write a book from the heart.”

These were the words of Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), at the launch of Beauty of the Heart: The life and times of Charlotte Mannya Maxeke by Zubeida Jaffer, the current Writer-in-Residence in the Department of Communication Sciences at the UFS.

Perseverance and dedication yields results

Writing a book from the heart is exactly what Jaffer, an award-winning South African journalist and author, set out to do. “When you make the choice to write a story, you need to be very dedicated,” she said.

As this is Jaffer’s third book, one would think that she would have no difficulty in putting pen to paper. On the contrary, she mentioned that it was, in fact, the hardest book she has written because the narrative was not easy to get hold of.

“I wanted Charlotte’s voice to come through, and it took my team and I three years of research and writing,” she said.

Maxeke’s story helps to shape South African society

The three-person panel, hosted by the UFS Sasol Library and SUN MeDIA, and chaired by Prof Jansen, included Jaffer and Dr Thozama April, University of Fort Hare historian who had done her PHD thesis on Maxeke.

Dr April said that Maxeke’s life story is an inspiring one, as it encourages a rethinking of established narratives. “These established narratives have made it possible for historians and researchers to write about the shaping of South African society,” she said.
