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.

Former President Nelson Mandela was part of the Moses generation that took people out of bondage. What the country now needs is the Joshua generation that will take it into the promise land.

This is according to political analyst and public commentator, Prof. Somadoda Fikeni. He was speaking to staff and students participating in the Global Leadership Summit, which took place on the Bloemfontein Campus from 8-20 July 2012. Prof. Fikeni took part in a panel discussion on Justice and Reconciliation. He and other panellists observed that there were still many challenges facing reconciliation in South Africa.

Referring to controversial statements made by Helen Zille, Julius Malema and Pieter Mulder, Prof. Fikeni said public discourse had become toxic and that the country was faced by a leadership crisis.

Ms Yasmin Sooka, a former Commissioner of the Truth and Reconciliation Commission (TRC) and Executive Director of the Foundation for Human Rights South Africa, asked if reconciliation had not come at the expense of redress. She said that to date there had been no restitution.

Ms Lihlumelo Toyana, a post-graduate student at the university, was also part of the panel. She told the audience that 18 years into democracy, there are still people waiting for justice. Toyana said young people hoped to see change and wondered if South Africans would ever sit down and have dialogue about the past. “We need closure; we need to take the country forward.”

The other panelists were lawyer, politician and former Human Rights Commissioner Prof. Leon Wessels; a professor from the University of Cape Town’s Law Faculty, Prof. Jaco Barnard-Naude; and psychologist, Prof. Alain Tschudin.
