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.

Course on sustainable development recognised at COP 17
2011-12-07

 

Some participants of the PED Nexus Programme during a field trip are from left: Jacques van Zuydam, Chief Director: Population and Development at the national  Department of Social Development; Prof. André Pelser, course coordinator (UFS); Prof. Sosten Chiotha, Director, LEAD Southern and Eastern Africa; and Dr Nola Redelinghuys, course facilitator (UFS).

The University of the Free State (UFS) received a nod of approval at the COP 17 Climate Change Conference in Durban for a short course it presents in partnership with the Chief Directorate Population and Development, United Nations Populations Fund (UNFPA), LEAD International and SANParks.

The UFS received an honourable mention in a press release from the Department of Social Development for the short course entitled ‘Leadership Training in Sustainable Development: The Population, Environment and Development (PED) Nexus’. The release was issued as part of COP17. It mentions that the course is recognised in a publication of the United Nations Development Programme (UNDP) as one of ten innovative experiences and best practices in population and development in the developing world.
 
Prof. André Pelser, UFS Professor in Sociology, says the university played a key role in the development and implementation of the course. The UFS has been presenting the course since its inception in 2005.   Similar courses under the banner of the PED Nexus, although in a totally different format, are also presented at the Nelson Mandela Metropolitan University and the University of Cape Town. A total of 21 courses have been presented nationwide since 2005, of which the UFS has hosted eight. More than 230 participants from all over the world have been trained in these eight short nine-day courses.
 
The PED Nexus Programme focuses on the interrelationships of population, environment and development and its significance for sustainable human development and is closely linked to the implementation of the national Population Policy for South Africa. The press release reads that the programme is implemented in the form of short courses that target professionals and managers in governments at all levels as well as non-governmental agencies responsible for the implementation of programmes related to sustainable development.
 
Prof. Pelser and Dr Nola Redelinghuys, also from the Department of Sociology, have recently been tasked by the National Department of Social Development to upgrade the course outline.  The next course will run from 17-25 April 2012. As in the case of pervious courses, the first six days will be hosted on our main Campus in Bloemfontein, whereafter course participants and their facilitators depart to the Golden Gate Highlands National Park for the practical part of the course.
