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.

UFS lays criminal charges against students
2008-02-28

Statement by Mr Anton Fisher, Director: Strategic Communication at the University of the Free State (UFS)

The management of the University of the Free State (UFS) has today instructed its attorneys to formulate criminal charges against four students who were involved in the production of an extremely offensive and racist video.

This follows other action taken late yesterday to prohibit two of the four students from the Reitz men’s residence from the campus. The other two students who can be seen in the video have since completed their studies and are no longer on campus.

Further steps are in the pipeline as the internal disciplinary procedure of the university must also take its course.

The Rector and Vice-Chancellor of the UFS, Prof. Frederick Fourie, has condemned the video and the gross violation of human rights that it portrays and has promised to deal swiftly and firmly with this matter.

This morning Prof. Fourie met personally with the workers who were tricked into taking part in the video and apologised to them face to face. Counselling is being arranged for the workers.

The management has also suspended lectures today in a proactive step to allow the emotions of staff and students to calm down. Lectures will resume tomorrow (Thursday 28 February 2008).

This follows a protest march earlier today against the extremely offensive and racist video which shows white students staging a mock “integration” of black workers in the residence.

After the march the management received memoranda from student organisations and two trade unions, NEHAWU and UVPERSU, about the video.

The students and the unions have made certain demands that the management will consider and respond to as soon as possible.

While the march proceeded peacefully, there have been sporadic incidents of intimidation and damage to property. Five students were arrested.

Prof. Fourie has appealed to students to act in solidarity with the management against the scourge of racism and to support the UFS in its policy to integrate student residences.
