Nkahiseng Ralepeli will join the Rhodes Scholarship cohort of 2019.

Aspiring lawyer and political prodigy, Nkahiseng Ralepeli, will soon join a cohort of Rhodes Scholarship recipients at the University of Oxford in the UK later this year. He completed his LLB at the University of the Free State (UFS) in 2018, and it comes as no surprise that this young achiever has his eyes set on greater heights.

As a student, Nkahiseng was always a cut above the rest, with his involvement in non-governmental organisations such as Corruption Watch and Debate Afrika, where he used debating to not only educate youth in South Africa but to engage various social ills that plague the country in whichever way he could. He represented the UFS at various debating tournaments such as the Pan-African Universities Debating Championships and the World Universities Debating Championships.

“This is something I’ve wanted for an incredibly long time. Receiving this scholarship is so important, and makes me feel that all my efforts and work have been validated. What I’ve learned is that regardless of the situation you’re born into, rich or poor, hard work is rewarded. I hope this experience will help me realise my dreams and career goals, but most importantly I want to have a significant impact in whatever space I find myself in and on the people I encounter,” said Nkahiseng.

As an Abe Bailey Bursary recipient, he is deeply interested in the transformation of African political theory and the establishment of various structures in the development and maintenance of African ‘infant’ democracies and post-civil wars. He later hopes to pursue a career in South African politics. His list of achievements keeps getting longer as he adds to it the Rhodes Scholarship. The UFS is truly proud to have an alumnus of this high calibre.

UFS alumnus receives PhD in Statistics from the University of Oxford

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.
