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.

Change and growth at the University of the Free State
2011-07-04

“Come gather round people, wherever you roam. And admit that the waters around you have grown…”

These are the opening lines of Bob Dylan’s iconic single The times they are-a changing. They are also extremely apt words to describe the excitement about the winds of change and growth blowing across the University of the Free State, not only academically, but also physically.

Over the past few months there has been non-stop construction and growth of a physical nature, with several new buildings being erected and new sculptures rising up all over the Bloemfontein Campus.

The most visible and probably the most striking of all the new structures is the brand-new main entrance to the campus. This stunning new feature welcomes visitors to the campus in Nelson Mandela Drive, in the colours of each of the university’s seven faculties.

Once through this beautiful new gate, visitors have a choice of new and exciting features to explore on the campus.

The first is the brand new climbing wall, which is located against the West Block and Chemistry Buildings. This new addition to the campus is available for use by all enthusiasts of this exciting sport.

The Office of the Dean of Student Affairs manages the administration of the wall and students who want to climb can book at their office in the Student Centre at the Thakaneng Bridge. In order to ensure that students do not use the wall without permission, and to prevent accidents, the wall is covered by a tarpaulin, which is locked when the wall is not in use.

Next on the list of new developments is the high-performance gymnasium which is currently still under construction. With this project the university wants to create a work environment for its staff that will not only contribute to the cultivation of maximum work performance, but also to staff wellness.

The centre with its foyer and administrative offices will also consist of a health desk, university sports institute, sports sales, a spinning and aerobic centre, and dressing rooms. The total area will extend more than 2114 m².

Progress on other building projects, which commenced last year, is also very pleasing. One of the projects is a new Education Building which is being constructed opposite the UFS Sasol Library. Upon completion, this building will be used for the training of maths and science teachers in the Foundation Phase. It will include three classrooms for 100 students each and an auditorium for 225 students as well as an office block. The auditorium will also be used as a classroom. The building has been designed according to environmentally friendly principles to save water and use power effectively. Construction is going swimmingly and should be completed soon.

Planning for the construction of more student accommodation on the Bloemfontein Campus as well as the Qwaqwa Campus is also well underway. On the Qwaqwa Campus, a residence with 200 beds is being constructed. This also includes a computer laboratory. According to the planning, this residence is near completion. Furthermore, four residences will be constructed on the Bloemfontein Campus. These residences are in the planning phase.

In order to place technology within reach of Kovsie students and thereby empowering them, computer laboratories were installed at all residences. The computer laboratories will eventually make provision for approximately185 computers for student use. Proper security is also planned to safeguard the equipment.
A brand-new building for the Faculty of Health Sciences is also proceeding rapidly. This building will include a lecture hall for 200 students, five venues for 100 students each, as well as offices. Students from the School for Medicine and Occupational Therapy will make use of these facilities.

The new building for the Faculty of Economic and Management Sciences between the Flippie Groenewoud Building and the Wynand Mouton Theatre is also coming along nicely.

On the university’s Qwaqwa Campus a new Education building is being constructed. This building will include a lecturing hall with 100 seats, four 50-seat classrooms, six offices, ablution facilities, biology and science laboratory, as well as an information technology laboratory for 60 students.

In the meantime, existing buildings are being renovated on all the campuses. This includes, amongst others, improvements to the Architecture Building, the Biotechnology Building and the quarters for service workers on the Bloemfontein Campus. Other improvements that have already been completed include renovations to the Odeion’s foyer and the Callie Human Centre.

A special memorial park for women, residential accommodation within a sports environment, and a botanical garden are also among the beautiful, exciting new sites to be seen on the campus.

Coupled with all the beautiful sculptures, funded by the Lotto Sculpture project, our university’s campuses will soon be a more vibrant, beautiful attraction.
