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 are the heart and soul of a university, a legacy that lives on for generations, bringing pride to the alma mater. Each year, the University of the Free State (UFS) through the Chancellor’s Distinguished Alumni Awards, celebrates its outstanding alumni, who have stood out among their peers, making waves in their careers, at home and abroad. The UFS Chancellor, Dr Khotso Mokhele, said the university plays a pivotal role in ensuring that students enjoy a life-long relationship with their alma mater.  He encouraged the UFS management to create opportunities to engage students during their years of study, in order to create this mutually-beneficial relationship into the future.

The Chancellor’s Distinguished Alumnus of the Year Award, the highest honour accorded to an alumnus, recognises the distinguished national or international achievements of its recipient. The award was presented to Vian Chinner, chief executive officer at Xineoh, a performance marketing company he founded in 2014. The company, based in Bloemfontein, with offices in Cape Town, Oregon in the US, and Vancouver in Canada, specialises in applying mathematical modelling and machine learning to optimise conversion in industries including real estate, mortgage banking and e-commerce. It has generated more than $30 million in revenue for its clients.

The Young Alumnus of the Year Award acknowledges the achievements of alumni who graduated within the past decade and was presented to Leah Molatseli, founder and managing director of Lenoma Legal, who graduated with an LLB at UFS in 2010.

The Cum Laude Award is bestowed upon an alumnus in recognition of excellence in any field, whether vocational or voluntary. The awards in this category were presented to three alumni:

David Abbey, Acquisition and Leveraged Finance Deal Maker at Rand Merchant Bank. David graduated with a BCom Accounting (RU) 2007 and a BCom Hons Accounting (UFS) in 2008.

Johan Eksteen, Agricon Pelleting, graduated with an MSc in Sustainable Agriculture in 1998, and received an MBA in 2005, both at the UFS.

Zola Valashiya, Co-founder and director: Debate Afrika and Schools Projects and Campaigns Manager at Corruption Watch. He graduated with an LLB (UFS) in 2014, and Masters of Public Administration (Central European University, Hungary) in 2016. He is a Mandela Rhodes Scholar (2015) and a Young African Leadership Initiative Mandela Washington Fellow (2017) and is presently featured on the Mail & Guardian list of top 200 young South Africans.

The Executive Management Award:
this service award is presented to an individual who has delivered exceptional service to the UFS and is not limited to alumni of the institution, current students and the community at large. The award was presented to Sarina Cronje, Head of Athletics at KovsieSport.

She graduated with a Bachelor of Science (UFS) in 1977 and a Postgraduate Diploma in Higher Education (UFS) in 1983. She is a mother and career woman, whose family carries the same passion and drive for sports that champions are made of.

The Kovsie Ambassador Award is bestowed upon a current student whose achievements have brought him/her distinction, benefited his/her community, and brought credit to the UFS.

Crystal-Donna Roberts graduated with a BA Drama and Theatre Arts (UFS) in 2005. She is an active television, theatre and film actress who has appeared in a multitude of theatre productions in addition to starring in Afrikaans soap opera “7de Laan, Getroud Met Rugby, Montana” and “Vallei van Sluiers” in which she won public favour. She is currently playing the lead role in the internationally acclaimed film, “Krotoa” which has won numerous awards including Best Film at the Harlem International Film Festival in New York. It also won the Award of Excellence at the International Film Festival for Women: Social Issues and Zero Discrimination, and many more.

Franco Smith, Director: Free State Rugby and Assistant Coach: Springboks. He graduated with a BA Human Movement Sciences (UFS) in 1996 and began his career in rugby in 1999 when he was selected for the Free State Under-18 Craven Week team. He became a regular on the Free State Under-20 and the UFS Shimlas teams prior to his Free State Cheetahs debut in 1992. Franco was reappointed backline coach of the Cheetahs and head coach of the Shimlas in 2015. With many accolades to his name an illustrious career in coaching and management over the years, the name Franco Smith should not be foreign to true rugby connoisseurs.

The Rector and Vice-Chancellor, Prof Francis Petersen, congratulated all the award recipients: “I applaud all alumni; you have made the city of Bloemfontein and the whole province proud.” The National Executive Alumni Chairperson, Dr Pieter du Toit, congratulated the award recipients and thanked the leadership of the university as well as the event organisers.
