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 and DRC Free State sign cooperation agreement
2013-11-27

The University of the Free State (UFS) recently signed a cooperation agreement for a period of five years with the DRC Free State. In this contract it is agreed that the university will offer theological training to DRC ministers.

With this agreement, the DRC Free State confirmed that the theological training currently offered by the Faculty of Theology meets the requirements and expectations of the church in such a way that her ministers can be trained within this context and ethos of the UFS. The Faculty of Theology believes that church involvement in the training of students of the DRC FS (as with all other churches), as well as the spiritual formation and guidance of those students, are important during their training and should be retained.

According to Prof Driekie Hay, Vice-Rector: Academic, the Faculty of Theology at the UFS is the only institution in Central South Africa that offers complete and comprehensive theological training.

“As the youngest of the faculties at the UFS, this faculty has developed a lot in a relatively short time and is firmly established on many levels. The faculty currently offers training in all theological disciplines, from undergraduate to PhD level,” says Prof Hay.

The Faculty of Theology offers a unique national and international contribution to the development of the church, society and academic theological environment. This is made possible through quality theological training and specialist research based on a framework of classical theological training and research.

The new cooperation agreement that was signed acknowledges the uniqueness and independance of both the DRC in the Free State and the Faculty of Theology as public institutions, and strives to serve the interests of both institutions best.

According to Prof Fanie Snyman, acting Dean of the Faculty of Theology, this new agreement proves that the UFS is not only training students academically, but is also concerned with the human aspect of its students.

“It is a privilege for the university to be associated and work together with the DRC in this way,” says Prof Hay. Rev Jan Lubbe, Moderator of the DRC Free State, also indicated that he is very positive and excited about the new agreement.
