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.

Disruption of academic activities on the Qwaqwa and Bloemfontein Campuses
2017-10-18

This morning, a group of students blocked the main entrance of the Qwaqwa Campus and handed a memorandum to the campus management. Academic activities were cancelled and will resume tomorrow (Thursday 19 October 2017).
 
Disruption of some academic activities occurred on the Bloemfontein Campus this afternoon after a meeting of students took place at the Student Lekgotla. Members of the executive management subsequently met with the Bloemfontein Campus Student Representative Council (SRC).
 
It was agreed that the students want to take part in a march to the provincial government office, demanding free education and the release of the Heher Commission’s Report on the feasibility of fee-free higher education and training by President Jacob Zuma. The executive management supports peaceful protests on matters that are of concern to our students and indicated that the march should include staff and students from the UFS and Central University of Technology, as well as other relevant stakeholders. A memorandum will be handed to the executive management tomorrow.
 
The situation on the Bloemfontein Campus is under control and is being closely monitored. Academic activities on the campus will also continue as normal tomorrow.
