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.

The latest success story of the Vice-Chancellor’s Prestige Scholars Programme (PSP) is that the first National Research Foundation (NRF) Y1-rating was awarded recently to a scholar while teaching in the Faculty of Economic and Management Sciences at the University of the Free State (UFS).

Dr Andrew Cohen received this distinguished rating on 10 November 2015. It is awarded to a “young” (younger than 40) scholar five years or less post-PhD, whose curriculum vitae predicts, according to a panel of international and local reviewers, that he is poised to become a leader in his field. Dr Cohen is a research fellow at the UFS.

This rating is a reflection of Dr Cohen’s record over the past eight years, and the scholarly environment he was part of at the UFS under leadership of Prof Ian Phimister. Cohen is currently a research fellow in Prof Phimister’s International Studies Group.  He taught economic history in the Department of Economics until September 2015, when he joined the School of History at the University of Kent.

Dr Cohen’s professional trajectory is emblematic of the visionary approach of the UFS Prestige Scholars Programme (PSP): to support prestige scholars with advanced mentorship, and the creation of a college of peers in order to nurture intellectual breadth and depth to generate knowledge over disciplines.

The PSP was initiated by Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS in 2011.

“Jonathan Jansen’s prestige scholars have become sought after in the academic community at large, as this recent appointment at the University of Kent indicates,” says Professor Neil Roos, co-director of the PSP. “Yet the alumni’s commitment to the programme, the university and their peers continues.”

Cohen is the editor (with Casper Andersen) of the five volume, The Government and Administration of Africa, 1880-1939. Dr Cohen’s next project is forthcoming from I.B. Tauris, The Politics and Economics of Decolonisation: The Failed Experiment of the Central African Federation.
