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.

The first International Congress on Calvin Research in Africa was this week presented on the Main Campus of the University of the Free State (UFS) in Bloemfontein. This was the tenth Calvin Research Conference presented. The conference is presented every four years.

The theme of the congress was: Reconciliation in the Theology of Calvin. Presentations were made about, amongst others, Calvin’s viewpoint regarding slavery and social justice. There was also a discussion about the extraordinary interest to record the original Calvin texts in databases and to make it available to researchers worldwide.

According to Prof. Dolf Britz, Director of the Jonathan Edwards Centre at the UFS, the objective of the congress was to study original Calvin sources critically. “An important part of the congress’ work is to publish an important part of Calvin’s work in a comprehensive text critical edition. This process is already well advanced and includes a number of unknown texts,” said Prof. Britz.

With its research on Calvin, the UFS emphasises the study of original theological sources. “This approach makes the Faculty of Theology part of the UFS’s strategy towards internationalisation. This is also one of the reasons why the UFS was selected by Yale University in America as partner in the recent establishment of the Jonathan Edwards Centre Africa,” said Prof. Britz, whose brainchild it was to also include young upcoming researchers with the study of original sources and classical languages such as Latin.

The congress was attended by researchers and academics from across the world. Twenty young, emerging researchers formed part of this group that was invited by the UFS. According to Prof. Britz, these young researchers are the top achievers at their respective universities, such as the North-West University, Stellenbosch University, Mukanyo Theological College in the Pretoria area and the UFS.

At this event, attended by more than 70 world-renowned Calvin scholars from countries like, amongst others, Taiwan, Japan, South Korea, Finland, Switzerland, France, The Netherlands, America, Germany and Hungary; UFS academics like Prof. Eric de Boer, Extraordinary Professor in Classical and Reformed Theology and students like Rev. Ntabanyane Tseuoa from Lesotho, read and presented papers as well.

According to Prof. Britz this congress was a very good opportunity to introduce the UFS to the rest of the world.
