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.

“Our education system needs quality teacher education.”

This was the message from Prof Jean Baxen, Deputy Dean of Research at Rhodes University in Grahamstown. She delivered the Education Public Lecture on ‘The lives of children, citizenship and teacher education: challenges and opportunities’ at the University of the Free State’s Bloemfontein Campus.

Growing up in White River, the rural areas of Eastern Transvaal (as it was previously known), Prof Baxen took the audience on a journey of the imagination. She shared stories of how she and fellow learners walked miles to get to school and how her son found himself in a situation of being unsure about his own racial identity, questioning what it meant to be ‘coloured’. She also related stories of how teachers are not sufficiently prepared to mediate information on HIV/Aids.

These stories revealed how little teachers cared, and also how difficult and challenging it is for learners to cope in such teaching and learning environments – thus calling for quality teacher education.

She stressed the fact that quality teacher education is needed in South Africa to assist in curbing the challenges children and fellow citizens come across in our broader society. “It is important that, as teacher educators, we should groom teachers to find and understand their identity, sexuality, and also the world they live in. There is an urgent need for us to hold ourselves and others accountable and to not distance ourselves and make it someone else’s responsibility – it is our joint responsibility as citizens,” she said.

We need a pedagogy that would navigate and start formulating a language that we could use to face these challenges, she proposed.
