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.

Celebrated author and educator, Deborah Meier, recently visited the university. Meier, ranked among the most acclaimed leaders of the school reform movement in the United States, spoke about democracy and education at a Critical Conversation hosted by the International Institute for Studies in Race, Reconciliation and Social Justice.

Speaking from her experience of the United States education system, Meier said that she had always been primarily concerned by the fact that schools were not engaging children in discussions about important and difficult topics such as democracy, race and class. As far as democracy was concerned, Meier pointed out that most schools viewed the occasional voting exercise as a lesson in democracy. However, as far as she was concerned, voting was the least important aspect of democracy. She admitted that democracy was almost impossible define, but in her view engaging with this difficulty was, in itself, an important democratic act – an act which could and should find its rightful place in the classroom.

Meier pointed out that children were effectively “incarcerated” for the six hours they spent at school every day. She expressed her grave concern about the fact that this time was not used to nurture and develop the considerable energy and creativity that young children had. Meier envisioned a school that could rise up to this challenge. At one point she mused, “Did I miss something? Did we invent some other institution that was taking on this responsibility?”
