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.

Research excellence is one of the major driving forces at the core of the University of the Free State (UFS). This striving for academic distinction has found embodiment within Trauma, Forgiveness, and Reconciliation (TFR) Studies. Headed by Research Fellow and Senior Research Professor Pumla Gobodo-Madikizela, the research unit is raking in achievements consistently.

Cornell University Distinguished African Scholar Award
Leading by example, Prof Gobodo-Madikizela received the prestigious 2016 Distinguished African Scholar Award from Cornell University recently. Being honoured with this award affirms an unusual depth of knowledge and experience in a field related to the recipient’s own work. Through this award, Prof Gobodo-Madikizela is now also affiliated with the Institute for African Development and the Psychology Department at Cornell University.

Ghent University fellowship in historical trauma
Another member of TFR has caught international attention. Lerato Machetela – a PhD student at the research unit – received an invitation from scholars at Ghent University in Belgium. Machetela will leave in September, where she will spend ten months in Ghent with experts in the field of historical trauma. She will be affiliated to their university’s Cultural Memory Studies Initiative and the Psychology Department. When Machetela submitted her PhD proposal on transgenerational transmisison of trauma among the youth in Jagersfontein to the UFS Psychology Department panel, “it was hailed as a unique project, and a first for the department,” Prof Gobodo-Madikizela says.

in Rwanda that has formed the basis of
her new book, Women Political Leaders
in Rwanda and South Africa: Narratives
of Triumph and Loss.

Book explores triumph and loss of female political leaders
TFR cultivates thriving authors actively, the latest being Naleli Morojele, who is pursuing a PhD in the field of Political Studies. Soon, Morojele will be launching her book, Women Political Leaders in Rwanda and South Africa: Narratives of Triumph and Loss. Through the stories of significant female Rwandan and South African leaders, the reader gains insight into these women’s early-life experiences, struggles, and successes. Perhaps even more pertinently, Morojele’s book also exposes the ways in which gender inequality still works to smother their roles as citizens and politicians.
