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.

2015 Varsity Cup Rugby gets going at UFS
2015-02-09

Kovsies! Are you ready?

It’s that time of the year again when Mondays mean rugby that rocks!

On Monday 9 February, the UFS Bloemfontein Campus will again be bustling with supporters as our Shimlas kick off their 2015 Varsity Cup rugby campaign against the University of Pretoria Tuks.

Students have already been made aware of Varsity Cup excitement during an activation event held at the Thakaneng Bridge on the Bloemfontein Campus on Wednesday 4 February. During this event, the Shimlas captain, AJ Coertzen, introduced his team while KovsieSport held promotional competitions.

New Shimlas coach, Franco Smith, is hoping to transfer his European coaching experience to the UFS first team as he heads into his debut Varsity Cup season. Smith previously held the head coach position at the Pro12 club, Benetton Treviso, between 2007 and 2013.

On the other hand, Tuks are likely to be very determined to bounce back in this year’s Varsity Cup season after missing out on the play-offs as defending champions in 2014.

Therefore, the Shimlas’ debut Varsity Cup match this year should be packed with excitement, thrills, and good old-fashioned running rugby to entertain the student population. Speaking of entertainment, there should be loads more of that happening next to the field during the half-time and strategy breaks.

So Kovsies, don’t miss the first of many great upcoming Shimlas home matches on Monday 9 February at 18:30, only at Shimla Park.
