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 unveils portrait of Ms Winkie Direko
A portrait of Ms Winkie Direko, former Chancellor of the University of the Free State (UFS) and Premier of the Free State Province and currently a Member of Parliament, was unveiled today during the last session of the UFS Council for this year on the Main Campus in Bloemfontein.

The portrait, painted by the gifted artist Ms Reshada Crouse, now hangs in the Council Chambers of the UFS.

Ms Direko was sworn in as Chancellor of the UFS in August 1999. She was the first black person and first woman in this position at the UFS. She was succeeded by Dr Franklin Sonn.

“Ms Direko had an exceptional legitimacy in the black community because of her role in black education in the Free State (as principal) and community leader in the difficult ‘struggle’ period. This former principal’s simultaneous insistence on transformation as well as discipline and order at an educational institution was exactly what the UFS needed at that stage,” said Prof Frederick Fourie, Rector and Vice-Chancellor, during the unveiling ceremony.

“She also played a special role to bring the UFS and the Free State Provincial Government closer to each other. Her comprehension for the own nature of a university helped in times when difficult decisions had to be made. She also realised the value of the university’s expertise for her government. The Premier’s Economic Advisory Council, with the UFS rector and academics like Lucius Botes and James Moses in leading roles, was formed to undertake important research on economic development strategies in the Free State,” said Prof Fourie.

In her speech Ms Direko said that it is an unique experience for her to be catalogued in the history of the UFS. “I am humbled and proud to be associated with the UFS,” she said.

Ms Direko said that the UFS is on the right track with its transformation process. “I will continue to convince people that the UFS is for everyone and will fight for that until the end. But, it is important to see a visible change concerning transformation. The UFS must bring its side and speed up the transformation process. I know that it is a difficult road, but we cannot hide from the realities of our time,” she said.
