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 medical students reach out to the community

A group of third-year medical students from the University of the Free State was responsible for many smiling little faces when they unveiled a entirely renovated crèche to its little students on Friday, 15 April.

Reinhardt Erasmus, Fathima Vawda, Veneshree Govender, Antoi Roets, Riaan Calitz, Motlalepula Mabizela, Tertius Potgieter and Chanel van der Westhuizen were the students responsible for the massive renovation work that went into the Beyang Bana Pele Creché in Mangaung.

The students tackled the project as part of a community service project and ensured that the 30 children who attend the crèche can look forward to coming to a safe healthy environment every day.

According to Riaan Calitz, they started the project at the beginning of the year by doing a needs analysis and talking to the children’s parents and teachers. They also involved the aid of an architect and quantity surveyor to calculate the needs of the crèche.

Next, they had to search for sponsors for their work, and struck it lucky when the Windmill Casino agreed to donate R100 000 to their project. They also managed to raise a further R5 000 as well as approximately R50 000 in goods and services donated by various other companies.

This money was enough to improve the safety at the crèche, install safe gas equipment in the kitchen, improve the insulation to ensure a warm winter, install new playground equipment and host several health and safety workshops.

“It took a lot of late nights and early mornings,” Calitz said. “Some of us also had to return from our holiday early, but it was worth it.”

He says the gratitude from the school’s children and teachers, as well as community members, who would stop and thank them for their help while they were busy working, makes it all worthwhile.

The students plan to stay involved with the crèche and say the renovation plan was drafted in such a way that when they move along, another group can simply pick up from their work with ease.

Mrs Sarah Mothoana, the crèche matron, thanked the students as well as everyone who assisted them in “creating a wonderful, safe and healthy environment for the children.”
