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.

It takes a village to raise a child

Motho ke motho ka batho. A person is a person through others

Want to make a difference in the world? Here is how

South Africa has one of the most spectacular coastlines in the world. Take the ribbon of golden beaches sweeping along the shores of KwaZulu-Natal, for instance. But just beyond the kiteboards dappling the ocean and fields of swaying sugarcane lies one of the largest informal settlements in the province: Amaoti. A place where barefoot children are skipping alongside poverty, and violent crime incinerates hope.

Nonetheless, that place could not keep Valentino Ndaba from graduating at the University of the Free State (UFS), and setting her sails for post-graduate studies.

A village
It takes a village to raise a child. This African proverb ripples across Valentino’s life story. “My gran always used to say education is your eternal bread. She still says it to this day. She has always instilled in me the importance of education,” Valentino smiles. Her grandmother has been but one of several champions in Valentino’s life.

Maalthee Dayaram – a teacher at Brookdale Secondary School that Valentino attended – noticed a budding talent in the young girl’s writing. With dedicated attention and ceaseless encouragement, Mrs Dayaram helped pave the way for this young writer. “You might be talented and have potential, but having someone actually believe in you and tell you that you have potential makes such a difference,” Valentino says. “I fell in love with writing, and had an idea that writing might be my future.” Dire economic circumstances threatened to snuff out any sparks of hope from that fragile future, though.

Aided by Lungisani Indlela (a non-profit organisation that provides children in the Amaoti area with school fees, uniforms, shoes, etc), Valentino clung to faith in the power of education. With unwavering single-mindedness, she consistently earned top grades.

Not if, but when
“Dreaming of my future, my gran would always say to me, ‘when you go to university’ or ‘when you have graduated’, this and that will follow.” Her gran’s words proved to be prophetic. As the final matric results were published in early January 2012, Valentino received a phone call that would change her life irrevocably.

That call came from the well-known South African humanitarian, Tich Smith. “Would you be willing to go to university in another province?” Smith asked. Never having travelled beyond her immediate surroundings, Valentino’s brave answer was: “Yes.”

A few days later, she walked onto the Bloemfontein Campus of the UFS.

Changing futures

Valentino proceeded to obtain a BA degree in Media Studies and Journalism in 2014. She has now set her sights on an honours degree, and envisions pursuing a Master’s degree in creative writing overseas.

“Without the support I received, I would have been stuck without a future,” she says. “University has shaped me into a better version of myself. I’ve grown intellectually, spiritually, and emotionally.”

You can bring about the same change for other students in need. By contributing to the UFS Student Bursary Fund Campaign, you can change the future not only of individuals, but of communities and of our country as well.

The impact of your financial support reaches far beyond its monetary value. It pulls families from poverty. It sends forth experts and visionaries into the world. It sets in motion a culture of giving.
