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.

Avant-garde filmmaker. Renowned feminist scholar. Revolutionary Prof Laura Mulvey.

2014-06-27

Prof Laura Mulvey – currently a professor at Film and Media Studies at Birkbeck, University of London, is about to visit the Bloemfontein Campus. As a tribute to her achievements, the UFS is bestowing an Honorary Doctorate on her during our Winter Graduation Ceremony. In addition, two events are scheduled during which the public can get to know Prof Mulvey and her films better.

Prof Mulvey is a hugely influential figure in the international arena of film and visual media. She is globally recognised as an eminent feminist film scholar and worked at the British Film Institute for many years. During the 1970s and ‘80s she exploded onto the scene as a prominent avant-garde filmmaker.

During her visit, she will discuss a film with Prof Annie van den Oever (University of Groningen) and some of her most renowned film material will also be screened.

Under the Skin of the City (Iran, 2001), directed by Rakhshan Bani-E'temad, will be screened in full on Thursday 3 July 2014. The film centres on the trials and tribulations faced by an Iranian family. This award-winning film will resonate with a South African audience because of the social issues it addresses. Prof Mulvey and Prof Van den Oever will also discuss the film afterwards.

On Saturday 5 July 2014, Prof Van den Oever and Prof Mulvey will have another discussion and the audience will be treated to snippets from her prominent films.

The details of these events are:
