Prof Tomas Vetrik, addicted to maths research

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.

Official opening: UFS earmarks R10-million to support national priorities

2006-02-06

The University of the Free State (UFS) is to align key areas of its academic and research efforts with national priorities through the introduction of five strategic clusters which would be funded by seedmoney of R10-million in 2006.

Speaking at the Official Opening of the UFS on Friday (3 February 2006), the Rector and Vice-Chancellor, Prof Frederick Fourie, said the academic and research work that will be done in the five strategic clusters would contribute to the development of Mangaung, the Free State, South Africa and Africa.

“It makes sense to concentrate the university’s human resources, our infrastructure, financial resources and intellectual expertise to ensure that the UFS makes a contribution to the country and the African continent,” Prof Fourie said.

“Strategic clusters will be organised on the basis that these areas of knowledge could become in the short term the flagships of the UFS, meaning those areas where the university currently has or in the very near future is likely to have some competitive advantage,” Prof Fourie said.

According to Prof Fourie, this strategic-cluster approach will be in line with the approach being designed by the National Research Foundation (NRF) to take national priorities into account and would enhance the quality of scholarship at the UFS.

The five strategic areas in which research and academic investment at the UFS will be clustered are the following:

Enabling technologies / Technology for the future;
Food production, quality and food security for Africa;
Development;
Social transformation;
Water resource and ecosystem management;

“Such strategic clusters are understood not only as research areas but as areas that also encompass strong undergraduate and particularly postgraduate teaching and a potentially solid scientific basis for service learning and community service research,” Prof Fourie said.

Within each of these clusters specific niche areas will be identified. Clusters could focus on one or more aspects of a particular discipline or could involve more than one discipline in researching a particular issue.

He said not all academic work and research being done at the UFS would be clustered in this way. Sufficient resources and support have been put in place for general research excellence in the past five years.

“Some of the spin-offs can have an important impact on industrial development, for example in the chemicals industry and may also create a basis for cooperation with provincial, national and international partners,” he said.
