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 hosts the first Southern African Young Scientists Summer Programme
2012-11-26

The University of the Free State is to host the first Southern African Young Scientists Summer Programme (SA-YSSP) from 1 December 2012 to 28 February 2013. 

This will form part of an annual three-month education, academic training and research capacity-building programme jointly organised by the National Research Foundation (NRF), the Department of Science and Technology (DST), and the International Institute for Applied Systems Analysis (IIASA), based in Austria.
 
The NRF, as the National Member Organisation (NMO), in collaboration with DST, has developed a novel and innovative initiative with IIASA to establish the SA-YSSP. This programme was officially launched by the Minister of Science and Technology during November 2011.
 
IIASA is an international research organisation that conducts policy-oriented scientific research in the three global problem areas of energy and climate change, food and water and poverty and equity (www.iiasa.ac.at). South Africa’s engagements with IIASA, and specifically with regard to the SA-YSSP, relate primarily to the DST’s Ten-Year Innovation Plan.
 
Aligned with the YSSP model that is presented by IIASA in Austria annually, the SA-YSSP offers scientific seminars covering themes in both the social and natural sciences. These seminars often have policy dimensions and aim to broaden the participants’ perspectives and strengthen their analytical and modelling skills, further enriching a demanding academic and research programme (www.ufs.ac.za/sa-yssp).
 
Keynote lectures are to be delivered by national and international leaders in their respective research fields, partly drawn from IIASA’s widespread network of alumni and collaborators, as well as from the NRF’s extensive international networks of excellence.
 
The programme is to be enhanced with specific field trips and cultural and heritage excursions that will involve networking with locally based research programmes. Supervisory teams of both IIASA and South African experts will guide a cohort of competitively selected South African and international advanced Ph.D candidates.
 
The programme will be opened on 2 December 2012 at the Centenary Complex by the Minister of Science and Technology, Mr Derek Hanekom, the Director/CEO of IIASA, Prof Pavel Kabat and the Vice-Chancellor and Rector of the UFS, Prof Jonathan Jansen. They will be joined by a number of Nobel Prize Laureates and luminaries representing the government, the diplomatic sector and Higher Education.
 
The programme is directed by a multidisciplinary team at the UFS that includes:
Prof Aldo Stroebel and Prof Neil Roos (Co-Directors)
Prof André Roodt (Dean of SA-YSSP)
Prof Martin Ntwaeaborwa and Dr Henriëtte van den Berg (Deputy-Deans of SA-YSSP)
Dr Priscilla Mensah and Dr Sonja Loots (Strategic Managers)
