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.

UFS hosts Fulbright senior specialist
2010-06-14

Pictured from the left, are: Prof. Aldo Stroebel (Director: International Affairs), Prof. Daryl Smith, Ms Dineo Gaofhiwe (Manager: International Research Funding Opportunities, UFS) and Mr John Samuel (Interim Director: the Institute for Studies in Race, Reconciliation and Social Justice, UFS).

The University of the Free State (UFS) has, for the past month, hosted Prof. Daryl Smith, Professor of Education and Psychology at Claremont Graduate University in the United States of America (USA), as a senior Fulbright specialist. She was hosted by the Institute for Studies in Race, Reconciliation and Social Justice, under the leadership of Mr John Samuel, who is its Interim Director. She helped in developing and establishing the research agenda of the institute.

A series of policy briefs and research papers will emanate from Prof. Smith’s tenure at the UFS, complemented by work of three additional Fulbright senior specialists who are joining the UFS early in the second semester. Prof. Smith met with various role-players and stakeholders in the domain of social justice, institutional change, transformation and diversity management, and will continue her association with the UFS at both the Institute and the Faculty of Education, in collaboration with its Dean, Prof. Dennis Francis.

Prof. Smith’s current research, teaching, and publications have been in the areas of diversity in higher education, leadership change, organisational implications of diversity, governance, and assessment and evaluation. She earned her Ph.D. in Social Psychology and Higher Education at Claremont Graduate University, her M.A. from Stanford University, and her B.A. in Mathematics from Cornell University.

Amongst many specialist missions, Prof. Smith served as part of two US delegations to the Ford Foundation-sponsored tri-national conferences (India, South Africa, US) on campus diversity in higher education that have taken place in South Africa and the United States. Her most recent book, Diversity’s Promise for Higher Education: Making it Work, is available from Johns Hopkins University Press.
