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.

“What do Africans have to say about the remaking of the global order?” was the opening question of Prof Tim Murithi’s lecture which was hosted by the Centre for Africa Studies (CAS) of the University of the Free State (UFS) to celebrate Africa Day on 25 May 2016.

The annual Africa Day Memorial Lecture, entitled: Africa and the Remaking of the Global Order, doubled as Prof Murithi’s inaugural lecture. He is CAS’s newly-appointed Extraordinary Professor, as well as the Head of the Justice and Reconciliation in Africa Programme at the Institute for Justice and Reconciliation in Cape Town. He made a compelling argument for the need for Africa to exert an active influence on international narratives of peace, governance, justice, and reconciliation.

“If we are waiting for American leadership to get us out of the quagmire of a situation we are in, we will be waiting for a long time,” said Prof Murithi.

The Head of the Centre, Prof Heidi Hudson, concurred with Prof Murithi’s suggestion of devising African solutions for African problems. She quoted Audre Lorde’s well-known assertion that “The master’s tools will never dismantle the master’s house.”

Remembering 1963
Over five decades ago, on 25 May 1963, the Organisation of African Unity was formed, and was renamed the African Union in 2002. Africa Day marks this pivotal point in the continent’s history. On this day, we reflect on the continent’s journey into democracy, peace, stability and socio-economic development. It is also an opportunity to celebrate African identity and heritage.

Continent-building dialogues
The UFS Sasol Library celebrated Africa Day with a book launch. Facets of Power. Politics, Profits and People in the Making of Zimbabwe's Blood Diamonds by Tinashe Nyamunda is a reflection of some of the challenges that Zimbabwe continues to face. It details the disadvantaged position which the country finds itself in due to greed, maladministration, and corruption, despite possessing large deposits of minerals.

In celebration of Africa Month, CAS has held a series of lectures by esteemed scholars from across the globe.  Earlier in the month, Prof Henning Melber presented lectures on Namibia’s independence and the African middle class. Kevin Bloom and Richard Poplak unpacked the issues surrounding Africa’s continental shift, while Prof Joleen Steyn Kotze focused on the possible fall of the African National Congress.
