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.

Our university rewarded the hard work of women at the university by unveiling a Women’s Memorial Garden at our Bloemfontein Campus on National Women’s Day, 9 August 2011. University Staff, students, some members of our Council and other guests gathered at the university for the unveiling of the new memorial garden.

Prof. Driekie Hay, Vice-Rector: Academic, told the somewhat 50 people at the unveiling that it was a historic day for the UFS, as this was a sign of how far the university have come. Prof. Hay told the women at the function to be proud of their achievements. She said the purpose of Women’s Day was to celebrate the historic struggle and sacrifices of all South African women, especially those who fought against racism and sexism.

The Women’s Memorial Garden consists of a botanical garden with more than 80 plant species. In the middle of the garden is a stone statue with a wild fig tree planted within. Prof. Hay told the guests that the tree’s numerous seeds represent unity and is an indication of real understanding, knowledge and faith, characteristics women at our university should pursue to ensure a sustainable and prosperous future for the UFS. The University leadership will now embark on a process to identify and recognise women from the university community who have made significant contributions during its 107 years of existence.

The memorial garden was designed by Habitat Landscape Architects. Mr Siegwalt Küsel, an architect at the firm, said the garden was developed to be a living monument to women. He said they hope that the garden will become an active learning space for visitors.
