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.

Faculty of Education hosts global education conference
2015-11-09



The Faculty of Education at the University of the Free State hosted the Annual conference of the South African Education Research Association (SAERA).  From the left are Profs André Keet, Director of the Institute for Reconciliation and Social Justice, Sechaba Mahlomaholo, Dean: Faculty of Education, Carlos Torres, keynote speaker and Professor of Social Sciences and Comparative Education, and former Director of the UCLA-Latin American Center, and Azlam Fataar, SAERA president.

National and global issues, trends, and research were discussed at the annual conference of the South African Education Research Association (SAERA), hosted by the Faculty of Education at the University of the Free State.

Considered as the highlight for educators, education researchers, and education policy makers, this conference is linked directly to the World Education Research Association (WERA), and to the American Education Research Association (AERA).

More than 400 delegates from national and international universities, as well as other interest groups such as the Department of Higher Education and Training of South Africa, have submitted abstracts on a variety of topics, spanning the different disciplines in education.

Keynote Speaker, Prof Carlos Torres, Professor of Social Sciences and Comparative Education, and former Director of the UCLA-Latin American Center, explained the importance of global citizenship education.

“The requirements to enable global citizenship education are clarification, bare essentials, principles, teaching methods, and agents. Global citizenship education is an intervention in search of a theory.”

Prof Torres's areas of theoretical research focus on the relationship between culture and power, the interrelationships of economic, political, and cultural spheres, and the multiple and contradictory dynamics of power among, and within, social movements that make education a site of permanent conflict and struggle.

Prof Teboho Moja, policy researcher and policy analyst for higher education in South Africa, spoke enthusiastically about changes taking place currently in higher education, changes that are driven by the recent demands of university students. Her keynote address dealt with equality and equity in higher education in South Africa.

“This conference is taking place whilst ‘something’ is happening in South Africa. This ‘something’ had to happen to achieve equity in higher education. Recent events on campuses left me proud to see the unity amongst students. Will the next phase in transformation and reform see that the doors of learning will be opened to all, as stated in the Freedom Charter?”

Prof Moja has authored articles on higher education reform issues in areas such as the governance of higher education, policy processes, and impact of globalisation on higher education.

“Hosting a conference of this magnitude validated the research work of the Faculty of Education in particular. It also positioned the Faculty positively in the national and international conversations around education research and gave the Faculty the opportunity to showcase its research, teaching, community engagement, and most importantly its organisational skills,” said Prof Sechaba Mahlomaholo, Dean of the Faculty of Education. According to Prof Mahlomaholo, staff (academic and support) in the Faculty have benefited greatly from listening to and networking with outstanding scholars from across the broad spectrum of education disciplines in the world. “These scholars also role modelled excellence in education research, which both our students and academic staff are now working towards emulating and surpassing,” he said.
