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.

New Genetics building on Bloemfontein Campus spirals into new frontiers

2015-09-11

On Thursday 3 September 2015, the Department of Genetics hosted the official opening of its new offices on the Bloemfontein Campus of the University of the Free State (UFS).

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, Prof Neil Heideman, Dean of the Faculty of Natural and Agricultural Sciences, and Prof Paul Grobler, Head of the Department of Genetics cut the ribbon, symbolising the opening of this building with its state-of-the-art facilities.

The new genetics building boasts a new administration block with a reception area, seven offices, a small committee room, and a seminar room for 50 people. Furthermore, the undergraduate laboratory block provides a laboratory for 150 students. The research block has facilities for 30 researchers.

This building also hosts a chemical waste sorting and storage facility. This is a first for the university.

Several sites were investigated for the new building, but due to its size and envisaged second phase, a “green fields” site was found on the western side of the campus. The main entrance caters for visitors from the north, students on foot, and those using the parking area in front of the library. The secondary south entrance is for those who use the dedicated parking area south of the building. The link between these two entrances is the spine of the building, a helix with services/buildings spaced on either side. The helix will be extended in the second phase to keep the circulation and linkage of buildings as simple as possible.

In his opening speech, Prof Grobler gave a breakdown of the history of the Department of Genetics. Today, this department, which opened its doors at the UFS in 1960, is proud of its 131 students and 46 honours students.

According to Major-General Edward Ngokha, Head of the Forensic Science Laboratory, students who graduate from the UFS in the field of genetics make excellent employees. The Forensic Science Laboratory has employed 25 honours students since the BSc Honours degree in Genetics was implemented in 2010.

“The UFS delivers education of high quality and high standards. Thank you for your contribution toward fighting crime by delivering well-prepared, committed employees,” said Major-General Ngokha.

The department presents programmes on population conservation genetics, plant molecular genetics, cytogenetics, forensic genetics, forensic science, human genetics, and behavioural genetics.
