Karla takes netball world by storm
Karla Pretorius, vice-captain of the Protea netball team, has become a leading player in world netball.

The University of the Free State (UFS) has produced a number of exceptional netball players over the years, but none quite on the level of Karla Pretorius, who is widely considered as probably the very best in her position.

 

A whole new level


Pretorius, who is completing her postgraduate studies in Dietetics, was already deemed one of the best when she left for Australia at the end of 2016; however, she has since risen to a whole new level. The Protea vice-captain plays for the Sunshine Coast Lightning in Australia’s Suncorp Super Netball league, the world’s leading competition. She is scheduled to return there again next year. Karla comfortably leads the stats with a total of 50 intercepts and was named in the Team of the Tournament.

 

According to the former Australian coach, Norma Plummer, who is now at the helm of the Proteas, “Karla currently has to be one of the best, if not the best, goal defenders playing at this moment in time.”

 

Karla’s ability to come through with speed-anticipating interceptions is something that is so exciting to watch. She is very versatile and can switch from one-on-one to split circle or other defensive styles, explained Norma. She says Karla is light in stature but physically very strong.

 

Keep on improving

 

According to Pretorius, who played for the Kovsies between 2009 and 2015, playing in an environment where every possible aspect gets attention – with emphasis on detail – has benefited her immensely. “Everything is done so professionally to eventually push you to become the best possible player.” Karla explained that she experiences challenges in many fields of her life but has the chance to play with and against the best players with different skills, which helps her to keep on improving and bettering her craft.

On 14 May this year, Dr DW Bester received a DPhil in Statistics from the University of Oxford. The entire ceremony, which was held in the Sheldonian Theatre in Oxford, was conducted in Latin, as has been the case for the past 800 years.

Dr Bester completed his undergraduate studies and his honours degree at the University of the Free State (UFS). “At first, I was only planning to study for a master’s degree, but was privileged to get an opportunity to do a PhD as well. I didn’t think twice!” he says.

Studies at the University of Oxford


Universities in England do not require a master’s degree for PhD studies. With the help of Prof Max Finkelstein from the UFS Department of Mathematical Statistics and Actuarial Science, Dr Bester registered for the DPhil programme in Statistics directly after his honours studies.

“The title of my thesis was: Joint survival models: A Bayesian investigation of longitudinal volatility. It dealt with a problem in the medical field to determine the cause of stroke risk: is it the absolute level of blood pressure, or the volatility thereof? The analysis of this question led to interesting models which needed advanced application techniques. I had to study these techniques and write programmes for their application.

Although Dr Bester is working currently as the technical head of a company that calculates insurance for power stations, satellites, rockets, and cyber risks, he would like to continue working with his Oxford supervisor in future to make the techniques they have developed more accessible for researchers outside of the field of statistics.
 
“Studying at Oxford requires hard work, perseverance, and a lot of luck. Luck plays a big role, since there are no guarantees that hard work will ensure you a spot in one of the top universities.

Regarding his studies at Oxford, Dr Bester thinks back on his exposure to the GNU/Linux operating system, and free software. “I have seen how valuable this is for analyses in practice. I also had the privilege of meeting the father of free software, Richard Stallman,” Dr Bester says.

2011 Rhodes Scholar

He was elected as Rhodes Scholar in 2011. According to Dr Bester, who has been interested in Mathematics since high school, the Rhodes scholarship was something of a fluke. He applied for the Rhodes scholarship on the recommendation of Prof Robert Schall of the Department of Mathematical Statistics and Actuarial Science.

Role of the UFS in his successes


In addition to the continued support from the team of passionate professors and lecturers at the UFS, the actuarial degree at the UFS is fraught with statistics. Emphasis is also placed on Bayesian statistics. This was crucial to his studies at Oxford. According to Dr Bester, this topic is emphasised strongly in the international statistics community.

Dr Bester regards the work done by two of his lecturers, Michael von Maltitz and Sean van der Merwe, among his highlights at the UFS. Since our first year, they have created an atmosphere of camaraderie among the students. “I think this contributed to the success of everybody. They also make an effort to present topics outside of the syllabus regularly,” says Bester.
