Prof Tomas Vetrik, addicted to maths research

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 receives record number of applications

2011-12-31

The University of the Free State (UFS) is looking forward to the start of the new academic year in January 2012, when thousands of new students will be joining the Kovsie family.

The UFS received almost 13 000 applications for studies in 2012. This is an increase of about 80% compared to the total number of applications received in 2010 for studies in 2011.

This increase is partly attributed to the university’s new method in approaching prospective students and the marketing initiatives followed during 2011. These included visits to various schools in the country by the Vice-Chancellor and Rector, Prof. Jonathan Jansen.

“This shows that the UFS is becoming a preferred place of study. Unfortunately, we can only take in about 4 000 first-years from these applications. We will, of course, choose the best and most diverse class of students,” says Prof. Jansen.

The university’s marketing initiatives will be intensified next year where students will take part as ambassadors in the university’s student recruitment campaigns for 2013.

Mr.Rudi Buys, The Dean of Student Affairs at the UFS, says Prof. Jansen’s visit to various schools in the country was very successful. This will be continued in 2012 and student leaders from residences, associations as well as the Student Representative Council will accompany him on these visits during the course of the year.

“These learners, just like our students, are part of a new generation of new democratic South Africans. Our students are excellent examples of youth leadership in the country and we are very excited about all our initiatives,” Mr Buys said.

The UFS is aware of the fact that learners will only receive their final Grade 12 results in January 2012. Final admission will therefore only be granted upon the submission of a certified copy of the matriculation results. Fax these results to 086 586 8947 or e-mail to applications@ufs.ac.za as soon as it is available.
