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.

Learning from industry experts is essential for students’ development. When that learning eases the financial burden of tuition fees, it is even better. TATA Africa has ensured that students from the University of the Free State (UFS) earn academic currency for displaying leadership and business skills.

Jehan Van Vuuren walked away with R40 000 in his student account, Hendrike Prinsloo earned herself R30 000, Stephan Strampe has R25 000 less to worry about when the 2016 academic year arrives, and seven other students managed to save their parents R20 000 each.

These top 10 Strategic Marketing students from the UFS Department of Business Management and Department of Communication Science took up the challenge of devising strategic concepts to be implemented by the Africa branch of TATA Group companies.

TATA Group is a multinational conglomerate which specialises in a wide range of products and services, such as automobile manufacturing, hotel accommodation, construction, textiles, food and beverages, amongst other enterprises operating under its banner. On 15 October 2015, the company’s Head Office representatives signed a cheque for R275 000 to reward the creative input of our students.

Lesle-Ann George won an academic bursary worth R20 000 for her individual effort, and was also part of one of the best four groups that won R10 000 each. She said the competition was an opportunity of a lifetime. The financial aid will be channeled towards the BCom Marketing Honours degree she intends pursuing next year.

The students’ ideas included market research for TATA motors, the development of a mobile application for the Taj Hotel, as well as innovative student-oriented social media, and guerrilla marketing strategies.

“This collaborative partnership between TATA Africa and UFS has provided the students with an opportunity to learn from key role-players in the industry and, in turn, to gain practical exposure to real-life industry happenings,” said Naquita Fernandes, a Business Management lecturer and the competition’s co-organiser.
