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.

Alumni inspired to keep flying the Kovsie flag high at reunion weekend festivities
2015-09-01

Dr Khotso Mokhele and Adv Roelf Meyer

The University of the Free State hosted alumni from all over the country on the Bloemfontein Campus during a weekend of exciting events, talks, and tours around the campus on 28 and 29 August 2015.

The celebratory events were kick-started with a leadership symposium hosted by Dr Marcus Ingram, Director: Institutional Advancement with Adv Roelf Meyer. The symposium was attended by current student leaders and the SRC Presidents Alumni Association. In his dialogue with the audience, Adv Meyer shared his experiences and personal growth in the process of bringing about democracy in the country with student leaders as change agents. “If you really want to contribute to change, it is not only an intellectual exercise; it is also a heart and soul thing,” he said.

The anchor event was the inaugural Chancellor’s Distinguished Alumnus Award Luncheon hosted by Chancellor, Dr Khotso Mokhele. Prof Jonathan Jansen, Vice-Chancellor and Rector, welcomed guests by highlighting the latest extraordinary achievements of UFS students and academic staff.

Keynote speaker of the day, Ms Nozizwe Madlala-Routledge, Executive Director of Inyathelo and a renowned politician, spoke of the role that universities have in preparing women for leadership roles and how they, in turn, can prepare society for female leadership.  She commended the UFS’s advancement efforts supported by the Kresge Foundation, which supports young people, to keep them in universities. “I am proud to say that the UFS’s efforts in advancement have achieved its goals.”

In his remarks, Dr Mokhele said “what draws a student back to his/her Alma Mater is the quality of the experience they had on campus.  This campus contributed to the transformation of this country through alumni such as Roelf Meyer and Kobie Coetsee.”  He said this initiative should create a lived experience for students on the university campus.  The Chancellor presented the Distinguished Alumnus Award to Adv Roelf Meyer, for his outstanding contributions to the human interests of South Africa, and his current work of facilitating peace processes around the world.

In accepting the award, Adv Meyer introduced Youth Zones, a project which he has been involved with for the past five years, empowering and supporting 40,000 youths in the Free State. In accepting the award, he said “I was a first-year student in 1960, my year group represented the most emphatic group of this university. There are many who came before and after us who well deserve this award, therefore, I accept it on behalf of all alumni.”

To wrap up the weekend’s festivities, former SRC President, Richard Chemaly, hosted the Faculty of Law alumni cocktail event at the CR Swart Auditorium.
Speaking at the event, Prof Caroline Nicholson, Dean of the Faculty of Law, said “A faculty cannot exist without its alumni, we need you to carry us.  Your continued support and collaboration is truly appreciated.”

Alumni and staff enjoyed further entertainment by well-known musical groups, Freshly-Ground and The Muses.
