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.

Meet the person behind the new #FaceOfFacebook

2016-05-19

Reuben “R” Davids

The votes have been counted, and we have a winner! After much excitement and a fairly close contest, Reuben “R” Davids emerged victorious from the top five contestants selected by our panel of judges. We chatted with the vibrant and enthusiastic Mr Davids to get a sense of the person who will be our Facebook ambassador for the next year.

What does the “R” stand for?

“Interestingly, some also know me as Vuyo. It's not a name on my birth certificate or anything; I just really like it. And I also coincidentally found out that it means “joy/happiness”, and I do enjoy being happy.”

What is your field of study, and how far along are you?

“I am pursuing a career in the economics field as a third-year BCom Accounting student in the Faculty of Economic and Management Sciences here at the University of the Free State.”

Are you originally from Bloemfontein?

“Yes, born and bred. I've been a Bloem Kid since day one.”

How is it that you ended up here, studying at the UFS?

“The UFS has always been one of my favourite universities. During my high school period, I was constantly exposed to people from my neighbourhood as well as schoolmates who performing excellently here at UFS, and it didn't go unnoticed. So I have always been drawn to the prestige that UFS carries.”

Which residence are you in, and what do you enjoy most about res life?

“I currently stay at home with the family, but for my first 2 years of study I resided at ConLaurês. What I enjoyed the most about res life is the freedom and independence that you get. It also enables one to participate in campus life much easier. It actually helps one grow and mature into the adult you're supposed to become with all the challenges and responsibilities that you're faced with.”

What do you hope to accomplish during your term as the #FaceOfFacebook?

“I enjoy the art of presenting (as well as being an MC), and being the #FaceOfFacebook will enable me to exercise that skill. Also, my interaction skills will be exercised. That being said, I would like to have those skills developed further by the end of my term as #FaceOfFacebook.”

What is your motivation in your studies, in taking part in this contest, and in life?

“I am an adrenaline junkie. I like taking on challenge; so what I normally do is I set a certain goal for myself and then take on the challenge to achieve that goal. That's my number one motivating factor. And I think I'm also inspired by the failures and successes of myself and of those around me.”

Reuben has already been featured in a #PeopleOfKovsies post on Facebook, and appeared in his first Facebook video covering the Open Day on our Bloemfontein Campus.
