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.

Two staff members from the Department of Political Studies and Governance, Prof. Hussein Solomon and Prof. Theo Neethling, were recently invited by the Osaka University in Japan to participate in a regional seminar in Lusaka, Zambia, on multinational peacekeeping and peace enforcement in Southern Africa.

The seminar was organised by the Southern African Centre for Collaboration on Peace and Security funded by the Japan Society for the Promotion of Science. Prof. Solomon presented a paper on the establishment of the Southern African contingent of the African Union’s African Standby Force, while Prof. Neethling presented his paper on United Nations peacekeeping operations in the war-ravaged eastern parts of the Democratic Republic of Congo.

The participation of Prof. Solomon, Senior Professor, and Prof. Neethling, Head of the Department of Political Studies and Governance, comes from a cooperation agreement between Osaka University’s School for International Public Policy (OSIPP) and the Faculty of Humanities at the University of the Free State. The agreement covers issues like joint collaboration projects, the exchange of staff and senior students and joint conferences. One of the key joint areas lay in the Southern African Centre for Peace and Security Studies, a consortium of several Southern African universities with Osaka University and the University of the Free State as its key pillars.

Other universities include the University of Zambia, Zambian Open University, University of Dar es Salaam, Mozambique-Tanzania Centre for Foreign Relations. Academics from other universities in the region, like Nzuzu University in Malawi, University of Botswana, University of South Africa, Stellenbosch University, University of Zimbabwe, are all in the network.
