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.

‘Your capacity for change is limitless’

 “You will change this campus, city, country, continent and the world, because you have the capacity for greatness,” Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), said.

He addressed the 2013 group of first-year students in the Leadership for Change programme at a farewell function before they will leave for universities abroad. The first 104 students from the 2013 total of 144 will depart on 18 September and return on 3 October 2013. The second group of 40 students will be abroad from 11 to 25 January 2014. The students are from the Bloemfontein and Qwaqwa Campuses. They will be accompanied by mentors from the UFS.

The students will visit 17 universities in the USA, Europe and Asia.

The first 71 first-year students in the Leadership for Change programme were sent abroad for two weeks in September 2010 to get intense exposure to the academic, social, cultural and residential lives of students in the USA. In 2011 the student number more than doubled and universities in Europe were included. In July 2012 the programme brought students from around the globe to the UFS for the Global Leadership Summit.

Prof Jansen inspired the young leaders, saying, “If you learn leadership values in your four years of study, a change will come. Build the new value system and take it into the country. Your capacity for change is limitless.”

He encouraged them to learn to know the stranger, not only abroad, but also the beggar at the street corner. “Learn to be comfortable with the beggar, as well as with the professor in the classroom.”

A stringent evaluation and training programme preceded the group’s visit abroad, and Prof Jansen could not formulate their achievement better: “I cannot tell you how proud I am of you.”
