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.

“One thing I can assure you: here academic work comes first.” This was how Prof. Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), set first-years parents’ minds at ease during the welcoming events of the first-years on the Main Campus the past weekend. 

The welcoming events, which took place over two days, were attended by a total of 7 000 first-years and their parents from across the country. 
 
Prof. Jansen also told the students and their parents that they were at the best place, by sharing his excitement about all the new students who decided to come and study at Kovsies. “You have overcome major obstacles in order to be here today,” he said at the welcoming.
 
With more than 90% new students who comply with admission requirements, this group of students promises to become true leaders of South Africa.
 
Prof. Jansen shared a few plans for the year with the audience. “As in 2010, we shall once again send a group of first-year students to universities later this year, not only in America, but amongst others also to Europe and Asian countries, amongst others, to learn more about different cultures and diversity. We aim to double the number of students who will be selected to 150 this year.” We can also look forward to, amongst others, a brand-new entrance and gymnasium for the Main Campus and four new hostels, two of which will be built on the Qwaqwa Campus.
 
Prof. Jansen emphasised the seriousness with which academic work had to be regarded, by referring to the compulsory class attendance that was implemented last year. “Since the inception of this arrangement in 2010, there was a 30% increase in students’ pass rate,” he said.
 
This year, for the first time, honorary awards were also given to young people who had rendered an exceptional service to the community. Anél Kleingeld, a 10-year-old learner from Trompsburg, and Mpho Phahlo from the UFS’s Unit for Students with Disabilities proudly received these awards. Anél made a remarkable contribution to George’s community when she encouraged learners from her` school to collect and deliver 700 litres of water for this community. Mpho made a point of assisting and motivating persons with disabilities at Kovsies to work hard on a daily basis.
