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.

It is time for the 2014 Winter Graduation on our Bloemfontein Campus. From 2 – 4 July 2014 Masters and Doctoral degrees will be bestowed on graduates from across all seven faculties as well as the School of Open Learning. These include the conferral of Medicine degrees on the South African Cuban trainees.

Wednesday 2 July 2014 at 14:30: School of Open Learning
The School of Open Learning will confer a total of 609 degrees this year – almost double compared to the 320 of last year.

Thursday 3 July 2014 at 09:30: Faculty of Natural and Agricultural Sciences
Prof Magdalena Blum will receive an Honorary Doctorat, DPhil honoris causa, at this event. Prof Blum is an Extension Systems Officer in Rome. She works for a specialised agency of the United Nations called the Food and Agriculture Organization. This organisation’s mandate is:
• to improve nutrition,
• increase agricultural productivity,
• raise the standard of living in rural populations and
• contribute to global economic growth.

Her position serves to modernise and strengthen rural advisory services, their systems and networks worldwide. She has filled this position for almost nine years.

Prof Blum is driven by a passion for development, humanitarian work and female upliftment, but most of all, to enable people to help themselves.

Blum’s life has taken her from a small German village to Africa, Asia and Europe – and she has made an impact wherever she went.

Thursday 3 July 2014 at 14:30: Faculties of Economic and Management Sciences, Humanities, Education, Health Sciences, Law and Theology
At this ceremony, Faculty of the Humanities will award an Honorary Doctorate, DPhil honoris causa, on Prof Laura Mulvey. She is a feminist film theorist and worked at the British Film Institute for many years. She is currently a professor at Film and Media Studies at Birkbeck, University of London.

Prof Mulvey was prominent as an avant-garde filmmaker in the 1970s and ‘80s. In collaboration with her husband, Peter Wollen, she co-wrote and co-directed:
• Penthesilea: Queen of the Amazons (1974),
• Riddles of the Sphinx (1977, perhaps their most influential film),
• AMY! (1980),
• Crystal Gazing (1982),
• Frida Kahlo and Tina Modotti (1982), and
• The Bad Sister.

In 1991, she returned to filmmaking with Disgraced Monuments, which she co-directed with Mark Lewis.
