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.

“A graduation ceremony epitomises every student’s academic dream and pursuit, and allows you to look back as you enter the professional career of your choice.”

These were the words of guest speaker Dr Mafu Rakometsi, Chief Executive Officer of Umalusi, that resonated through the Callie Human Centre at this year’s Summer Graduation on the Bloemfontein Campus. He mentioned that today graduates would look back at a journey that started with hesitant steps, and despite all their ups and downs, they had managed to make it this far.

During the afternoon session, Prof Lis Lange, Vice-Rector: Academic, at the University of the Free State (UFS), said that graduations were always an occasion for celebration and this year, there were two reasons for these celebrations.

 “The first is simply that we made it through a difficult 2016 and the secondly because we are celebrating two crucial professions that will attribute to the well-being of this country, namely teachers and health practitioners.”

Meaningful graduation ceremony for Ferial Haffajee

This year, the UFS had the privilege and honour to confer editor-at-large at The Huffington Post SA, Ferial Haffajee, with an honorary doctorate in the Faculty of the Humanities.

Speaking after the graduation ceremony, Dr Haffajee said, “It was really, really meaningful for me, because I’ve never been able to graduate. When I finished university, it was during the struggle against apartheid, so we didn’t graduate. It was a wonderful day and wonderful to see the role that young people are playing on this campus.”

“Dr Ferial Haffajee has made a significant contribution to press freedom in South Africa. She is known both nationally and internationally for the work she has done and therefore it is an honour to welcome her as a Kovsie. She is one of the people who represent the values of the UFS. We are proud of her and we wish her great success,” said Prof Milagros Rivera, Head: Department of Communication Science and acting Dean of the Faculty of the Humanities at the UFS.

Inspiration drawn from graduation ceremonies

During his address, Dr Khotso Mokhele, the Chancellor of the UFS, made special mention of many that inspired him at the graduation ceremonies.

His inspirations included Dr Ambrotius Swartbooi, who suffered a spinal injury from a near-fatal car accident which left him paralysed and a quadriplegic, yet who still managed to receive his doctorate; Setsoane Ntseki, a matriculant with poise and an incredible voice, who delivered the song item; Judge Ian van der Merwe, Chairperson of the Council at the UFS and a close friend of Dr Mokhele, with whom he worked for many years; as well Dr Haffajee, a trail-blazer that many look up to.

Damian Viviers was recognised as one of the youngest PhD graduates in the Faculty of Law, where he received a PhD in Mercantile Law. He is a research fellow in the Department of Mercantile Law, and was recently appointed as candidate attorney in the commercial department at Phatshoane Henney Attorneys.

In closing, his message to the class of 2016 was simple, that even though the world and our country may find itself in an odd space now, the graduates needed to remember that even though they would become leaders, there was always something bigger than themselves.

“Go out there and do us proud. Come back and plough back into this institution not only with your money, but your skills and time too.”
