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.

Wayde changed the game – Naidoo

For a long time, AB de Villiers and Chad le Clos have dominated fan support in South Africa, but Wayde van Niekerk changed the game.

This was what Kass Naidoo, well-known sports journalist and cricket commentator, tweeted after the Kovsie athlete, Wayde van Niekerk, made a clean sweep at the tenth SA Sports Awards in his home town, Bloemfontein, on Sunday 22 November 2015.

According to Naidoo, the golden boy from the University of the Free State (UFS) is now the hottest property in South Africa, and should be watched during the 2016 Olympic Games in Rio de Janeiro.

Hat trick for Kovsie athlete
Naidoo was one of several celebrities to congratulate Van Niekerk on Twitter after Wayde received a hat trick of awards in the Sand du Plessis Theatre. The 400 m athlete was named Sports Star of the Year, Sportsman of the Year, and was crowned as winner in the People’s Choice category.

Apart from this, a humble Van Niekerk received total prize money of R1,1 million and two luxury Mercedes Benz vehicles - one for Sports Star of the Year and one as People’s Choice winner.

Big names outperformed
What makes his awards even more remarkable is the fact that he has outperformed several big names.
In addition to De Villiers and Le Clos, the tennis player, Kevin Anderson, the swimmer, Cameron van der Burgh, and the athlete, Caroline Wöstmann, were all nominated for Sports Star of the Year.

For the People’s Choice Award, Van Niekerk beat De Villiers, the cyclist, Ashleigh Moolman-Pasio, (who was crowned Sportswoman of the Year), Le Clos, and the wheelchair tennis player, Lucas Sithole. The public voted for this award.

Le Clos was nominated with the mountain biker, Greg Minnaar, for Sportsman of the Year.

Best is yet to come
“I don't think we have seen the best of Wayde. Hopefully that will come in Rio next year, along with a gold medal,” Naidoo tweeted.

The Springbok winger, JP Pietersen, also congratulated Van Niekerk on the social network, saying that he deserved his award as Sportsman of the Year.
