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.

Freedom of religion is enshrined in the South African Constitution, states that everyone has the right to freedom of religion, which more specifically entails the freedom of conscience, religion, thought, belief and opinion. It makes provision for the protection of religious communities in South Africa. Consequently, the maintenance and protection of such a right is of fundamental importance.

Prof Shaun de Freitas, Associate Professor of Law at the University of the Free State (UFS) specialises in constitutional law, with a specific focus on the right to freedom of religion, and has produced several publications in the field. The latest is titled “Transcending the Private-Public School Divide in the Context of the Right to Freedom of Religion in South Africa”, Chapter 19, in Religious Freedom and Religious Pluralism in Africa – Prospects and Limitations published by Stellenbosch University in 2016.

Prejudice a challenge in all societies
There are numerous challenges faced by religious groups around the world concerning prejudice, association with terrorism and political power and influence. Therefore, research in this field becomes important in helping to uphold the rights and freedoms of religious minority groups, to be able to foster understanding between communities.

Balancing responsibility and religious rights
His current focus is on challenges that have arisen in South Africa, more specifically pertaining to the right of medical practitioners to object conscientiously towards participating in certain medical procedures, the parameters of freedom related to religious associations and the inclusion of religious expression in public schools. These matters are also relevant to many other parts of the world (including, ironically enough, those democratic societies that endeavour to make diversity flourish).
