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.

Professor awarded by Cardiff University for exceptional teaching and research record

2015-10-20

Prof Pieter Duvenage

Cardiff University is one of the best research universities in the United Kingdom (UK) and the world. In 2014, Cardiff was ranked number 2 and 5 among UK universities in the Research Excellence Framework for impact and quality, respectively.

Annually, Cardiff selects and recruits the most outstanding teachers and researchers from across the globe. This year, this institution bestowed on Professor Pieter Duvenage the title of Honorary Professorship in Political Philosophy for his contribution and commitment to philosophical research in South Africa and internationally. Prof Duvenage is Head of the Department of Philosophy at the University of the Free State (UFS).

Prof Duvenage has authored and co-authored four books, publishing almost 40 accredited articles in journals and books. As a distinguished scholar, he displays immense dedication to the investigation of the political implications of intellectual traditions.

Since 1997, Prof Duvenage has been lecturing philosophy as an associate professor, full professor, or visiting professor at various South African and Australian universities. He was appointed as Head of the Department of Philosophy in 2011, where he continues to explore his interests in Phenomenology, Critical Theory, and South African Intellectual History.

His rich academic history had earned him the prestigious five-year Honorary Professorship at Cardiff’s Department of Politics. In 2014, the same university invited Prof Duvenage to be a Professorial Fellow of the Collingwood and British Idealism Centre for an indefinite period.

Professor David Boucher, Director of the Collingwood and British Idealism Centre, has played a crucial role in initiating both processes. According to Prof Duvenage, “Professor Boucher is a respected British academic and a Distinguished Visiting Professor at the University of Johannesburg.”

When Boucher announced the good news, Prof Duvenage was very surprised. “The appointment came as a total surprise. I never studied there [at Cardiff University], therefore it was purely through academic networks.”

Considering Cardiff’s reputation and Prof Duvenage’s exceptional skill sets and values, his relationship with the world-leading university in research is bound to blossom.
