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.

Student gives hope to childhood cancer patients

2015-10-16

Siphokuhle Jama believes that the underprivileged are also destined to reign.

The inaugural ‘Dance and Musical Childhood Cancer Fundraising Day’, held on Saturday 26 September 2015 at the Free State Childhood Cancer (CHOC) Foundation, was “a huge success,” according to Siphokuhle Jama, the organiser.

Siphokuhle is a second-year BSc Agricultural Economics student at the University of the Free State (UFS), who has devoted his life to bettering the lives of the less fortunate. The 21-year-old self-proclaimed motivational speaker, entrepreneur, and budding author was inspired by his humble beginnings to found the Destined to Reign Foundation, which champions various community initiatives in both his home town of Mtata and Bloemfontein.

To support the fight against childhood cancer, the young philanthropist took it upon himself to invite music and dance fanatics either to perform or to enjoy spectatorship for a good cause. The impressive support received from the UFS, Universitas Academic Hospital, and Central University of Technology (CUT), various artists, and the community has contributed towards ensuring that the inaugural fundraiser was a prelude to annual events to come.

Singers, dancers, and poets entertained the audience with vigour, making the day one of the most special for the young children, who spend their days and nights at the CHOC House, with little to do but undergo radiation and chemotherapy and await a discharge date. .

All proceeds went towards basic needs, such as food, toiletries, and clothing for the children residing at the House, which is located in the same suburb as our university. In addition to accommodating dozens of cancer patients and their mothers, the House also assists with the treatment and rehabilitation of children suffering from life-threatening blood disorders. Thus, the fundraiser served to promote awareness of these health conditions.

Siphokuhle’s passion for giving hope to the underprivileged was unveiled by a school community engagement project 14 years ago. He has never looked back.“It has always been in my heart to serve my community,” he said.
