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.

UFS cracks down on crime on campus

2006-03-15

A comprehensive plan to step up the security on the Main Campus of the University of the Free State (UFS) in Bloemfontein, was approved by the Executive Management (EM) this week.

“The plan briefly comprises of the introduction of reasonable and affordable measures that will promote a safe campus and working environment,” said Rev Kiepie Jaftha, Chief Director: Community Service at the UFS.

“With the plan we want to try and create a user friendly, but safe campus,” said Rev Jaftha.

The plan is the result of an intensive investigation about campus security done by an EM task team.

The following measures will be implemented immediately in phases:

The five current vehicle entrances and exits will remain (i.e. the gate at Nelson Mandela Avenue, the gate at Roosmaryn, the gate at Agriculture, the Wynand Mouton Avenue gate and the Furstenburg Road gate).

The number of smaller pedestrian gates will be reduced and security at those remaining will be increased.
The fences around the campus will remain, upgraded and patrolled on a daily basis.

The security measures at high risk areas (e.g. the Kovsie Church) will be stepped up and the fences in these areas will be electrified.

Vehicle exit control will be stepped up at the gates by means of a mixture of electronic and compulsory visual security control.

Public areas, streets and footpaths will be patrolled and shrubs and trees will be cut and pruned. The streets, footpaths and buildings will also be lit.

Speed reducing mechanisms will be implemented before and after the security control points at all the gates.
Additional staff will be appointed to facilitate the flow of traffic at the gates.

“Over and above these measures, the EM also approved in principle the installation of electronic equipment at all the entrance gates. This will include the installation of cameras,” said Rev Jaftha.

According to Rev Jaftha the installation of the electronic equipment will be complemented by the compulsory cutting and restarting of engines for all vehicles exiting the gates. The measure has been in force since 1 February 2006.

Last year special measures were put in place to safeguard residences and their inhabitants when security guards were placed at all the ladies residences. These measures will stay in force.

“Regular audits will be done to determine the effectiveness of the strategies and systems. Although crime in and around the campus grounds can never be completely eradicated, we want to strive to create an environment on campus and in the workplace where it can be limited,” he said.
