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.

“We have the capacity to make a success of South Africa. We have incredible people who refuse to leave the country and want to make a difference.” This is according to Archbishop Emeritus Desmond Tutu who was speaking at the University of the Free State (UFS) today.

Dr Tutu took part in a dialogue with Prof. Mark Solms, owner of the Solms-Delta wine estate in Franschhoek.Prof. Solms is also an A-rated scholar and the Head of the Department of Psychology at the University of Cape Town.The theme of the dialogue was “Living Reconciliation: Winds of Change in Franschhoek and Transformation at Solms-Delta Wine Estate”.

Prof. Solms led an initiative to transform the lives of farm workers on the estate through the Wijn-de Caab Trust. This initiative was extended to empower the wider community of farm dwellers when Prof. Solms co-founded the Delta Trust and the Franschhoek Valley Transformation Charter.

The dialogue was the second in the Dialogue between Science and Society series and was facilitated by Prof. Pumla Gobodo-Madikizela, Senior research professor on Trauma, Forgiveness and Reconciliation at the UFS. The Dialogue series aims to inspire new ways of thinking about responsible citizenship. It also highlights the unique and important ways of engaging with the critical issues of social equality, social justice, social transformation and reconciliation in South Africa.This morning Dr Tutu said the work done in the Franschhoek community is proof that people cannot prosper alone if others are also not prospering. “We belong together. Why did it take us so long to realise it? South Africans have the capacity to make South Africa a better place. It is unacceptable that people go hungry and go to school under trees. It is unacceptable that they still have no books in the third term, and that the pass rate is 30%.

“Is this why we struggled, why people died? We want to go to our graves smiling… we will not be allowed peace and stability if we do not attend to the problems.”

Prof. Solms said the miracle of the political transformation did not trickle down to the people. A lot has been done, but much more needs to be done. “It can only be done by us. It is not the government’s responsibility. The way we live as a result of apartheid is that we are a deeply divided society. We must recognise this and do something to change it.”

He encouraged people to think “small”. An individual cannot change the whole country, but the changes in his community are there to see.

Dr Tutu also congratulated the UFS on becoming a truly South African university, recognising the transformation of the past few years.

The dialogue was presented at the Global Leadership Summit that 250 students and academic leaders from 21 international universities are participating in. The summit runs until Friday 20 July 2012.
