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.

UFS receives research grant focusing on enablement of non-profit organisations

2011-01-20

Prof. Mabel Erasmus

The University of the Free State (UFS) has received a research grant to the value of R1,1 million from the National Research Foundation (NRF) to conduct research on community engagement, with the emphasis on knowledge as enablement – a Non-Profit Organisation (NPO) focus.

This was the first time the NRF had requested applications for research with a focus on community engagement (CE). With the grant, the UFS has become one of the first recipients of a research grant that focuses on community engagement.

The overarching research question that will be dealt with is how Higher Education Institutions (HEI) and the NPO sector can establish long-term, research-based collaborative engagements that will be mutually empowering and enabling through joint, reciprocal knowledge-based activities and capacity building.

The contention that this proposal is based on, is that HEIs have limited knowledge of the NPO sector and thus are unable to be fully responsive to the challenges that NPOs face. What is more, it is very likely that staff and students from HEIs do not have an adequate grasp of the experiential understanding, contextual community knowledge and practical know-how that NPO practitioners have, and hence do not appreciate the crucial contributions that they can make with regard to meaning-making processes aimed at improving some of the harsh South African realities.

According to Prof. Mabel Erasmus, Associate Professor and Head of the university’s Division: Service Learning, which submitted the research proposal to the NRF and is the grant-holder, the university would like the information generated by the research to be beneficial to both HEIs and the NPOs. “Knowledge regarding NPOs, specifically their challenges and information about what they are doing, will be invaluable to HEIs. At the same time, the research must benefit the NPOs with knowledge to improve their practice and strengthen their functioning.

“The research will take place in close collaboration with the NPOs, as their inputs are crucial. The research will thus not be ‘about’ them but ‘with’ them.”

“We do not want to send our students for community-based education or as volunteers to NPOs year after year and it does not mean as much to them as these organisations would hope for. With the research process we would like to strengthen NPOs, to build their capacity and give them our whole-hearted cooperation,” she said.

Funding received from the grant will be applied over a period of three years. Except for the study grants for five Ph.D. students and four master’s students, the grant will further make provision for a number of workshops, a local conference, a publication and presentations at international conferences on this matter. The research team of 22 persons includes academics from other HEIs such as the Central University of Technology, University of Zululand, University of Johannesburg and Monash SA. Several staff members of NPOs also form part of the team, including REACH (Bfn), Childline (FS) and others.

Prof. Erasmus said that the UFS was one of a few institutions that were currently conducting research to this extent on the link between the NPO sector and HEIs within the field of community engagement.
