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.

Prof. Letticia Moja a winner in her category

Prof. Moja a finalist in award 
'Every member of staff is important to me'

Michelle Cahill - Bloemnuus

IF you are in need of a dose of inspiration, try and get an appointment with Prof. Letticia Moja, the Dean of the Faculty of Health Science at the University of the Free State. It will not be easy as she has an extremely tight schedule, over and above being a finalist in the 2004 Shoprite/Checkers Woman of the Year competition.

 

Although not a born and bred Free Stater, this dynamic woman has come to love the Free State. "Once you get past the mindset of a small town and all the negatives surrounding it, it is an absolutely wonderful experience," Moja said.

Moja was born in Pretoria and grew up in Garankuwa as the second eldest of five children. "That was nothing special. I was not the eldest and I wasn't the youngest," she quipped. She had two younger brothers, one of whom died in a car accident and then two sisters.

She went to school in Pretoria and her first contact with the Free State was when she wrote her matric at Moroka High School in Thaba Nchu. "That was one of the best schools for us at that time," she says. After completing matric, she went on to study medicine in KwaZulu-Natal.

In 1982 she returned "home" and completed her internship at the Garankuwa Hospital. Hereafter she specialised in gynaecological obstetrics at Medunsa.

She became the head of the gynaecological obstetrics unit and later opened a branch in Pietersburg.

"This was just about the most heart-rending time of my life. You saw people travelling for up to three days just to see a doctor," she says. "Here we really interacted with the community."

In 2001 she was invited by the University of the Free State to apply for the job of vice-dean of the Faculty of Health Science. "I wasn't too keen," she says, "but they kept on calling to find out if I had applied or not," she says with a smile. "Eventually I gave in and was appointed."

She thought she would work a couple of years under Prof. Kerneels Nel, then the dean of the faculty. "Unfortunately that was not to be. I had hoped that I could learn from him," Moja says.

Prof. Nel died of a heart attack in 2003 after which Moja deputised for him before being appointed as dean.

"This brought along a whole newset of challenges," she says, "Now I have to work out budgets and I need to know what human resources are," she jokes. This has prompted her to take up her studies again and she is currently doing her MBA.

"It has certainly been a challenge to go into management and without my support structure I most certainly wouldn't have been able to do it," Moja says.

Moja is actively involved in her church and serves on various committees including the Health Professional Council where she is acting president of the Medical and Dental Board and the Provincial Aids Council.

To her no job is menial. She recalls when she used to have "high tea" with her staff in Gauteng and Limpopo. "One of the cleaning ladies used to think her job was menial. That is just not so. No hospital can do without even the lowest position. Imagine stepping over rubbish while you're trying to catch a baby. To me everybody is important no matter what you do. "

Moja's eldest daughter is studying for her B.Accounting degree at Wits . Her youngest daughter is in Gr. 9 at Eunice and she has also brought along her niece, who is in Gr. 8 at Eunice. "You see, we need to be three girls in the house."
She feels honoured to have been nominated by the institution especially as it is traditionally male-dominated. "It is not about me, but about the support structure. Nobody can do it on their own. It is a team effort."
