Prof Hendrik Swart named among South Africa’s most influential leaders

29 May 2025 | Story Martinette Brits | Photo Kaleidoscope Studios

Prof Hendrik Swart from the University of the Free State (UFS) Department of Physics was recently honoured at the Golden Key Honour Society Southern Africa’s Black Tie Gala Event, held on 23 May 2025. The event celebrated 300 of South Africa’s most influential leaders across academia, industry, government, and the financial sector.

Prof Swart, who is an NRF B1-rated researcher and currently also holds the SARChI Research Chair in Solid-state Luminescent and Advanced Materials (2023-2027), described the recognition as both meaningful and affirming at this stage of his academic journey.

“Being recognised by such a prestigious organisation is a meaningful acknowledgment of my academic efforts and personal dedication,” he says. “It was a moment of validation and inspiration, reminding me that hard work truly pays off.”

While the exact selection criteria were not publicly detailed, the emphasis was placed on academic excellence, scholarship, and leadership.

This is not Prof Swart’s first recognition from the Golden Key Honour Society. In 2012, the UFS student chapter awarded him honorary membership for his contributions as a mentor and supervisor – an early nod to his lasting impact on student success.

“The student chapter here on campus gave me some recognition by awarding me honorary membership,” he recalled. “It meant a lot to me as a mentor.”

The gala itself offered more than accolades – it created a space for meaningful exchange. Prof Swart reflected warmly on reconnecting with one of his former students from the early 2000s, calling it a highlight of the evening.

Looking ahead, Prof Swart welcomed the society’s plans to continue this initiative across the country.

“This was the first time they had an event like this, but more are expected to follow. I see it as a good initiative to mingle with other sectors in South Africa.”

Harvard couple to present lectures on Biostatistics and Mathematics at the UFS

2015-12-07

Professor Donald Rubin

Prof Donald Rubin (John L. Loeb Professor of Statistics at Harvard University) and Elizabeth Zell (MStat - mathematical statistician in the Division of Bacterial Diseases) will visit the University of the Free State (UFS) where they will present lectures on their respective work.

Over his prestigious academic career, Prof Don Rubin’s 400 publications and 13 books have earned him around 180 000 citations at an h-index of 113. He is one of the most cited statisticians/mathematicians/economists/psychologists in the world over the last 10 -15 years. He has supervised 35 PhD candidates as sole-supervisor, 17 more as co-supervisor, with a further eight in the pipeline.

Prof Rubin who will meet with UFS academics in the Department of Mathematics and Actuarial Sciences will also deliver a lecture: Rerandomisation to improve covariate balance in experiments.

Randomised experiments are the “gold standard” for estimating causal effects, yet in practice, chance imbalances often exist in covariate distributions between treatment groups. If covariate data are available before units are exposed to treatments, these chance imbalances can be mitigated by first checking covariate balance before the physical experiment takes place. Provided a precise definition of imbalance has been specified in advance, unbalanced randomisations can be discarded, followed by a rerandomisation. This process can continue until a randomisation yielding balance according to the definition is achieved. By improving covariate balance, rerandomisation provides more precise and trustworthy estimates of treatment effects.

Prof Rubin received an honorary professorship from the Faculty of Natural and Agricultural Sciences at the UFS.

Elizabeth Zell

The lecture will take place on:
Date: Tuesday 8 December 2015
Time: 16:00
Venue: Albert Wessels Auditorium, Bloemfontein Campus

Zell earned her Master’s degree in Statistics at North Carolina State University, and for more than two decades, was an active bio-statistical researcher in various offices of the Centers for Disease Control (CDC). Since 2013, she has been the Principal Statistician and President of Stat-Epi Associates, Inc. Her 150+ publications have earned her 14 500 citations at an h-index of over 50. She is a Fellow of the American Statistical Association, and, in 2010, she received the Statistics Section Government Award for outstanding contributions to statistics and public health by the American Public Health Association. During her career at the CDC, she earned more than 20 CDC research awards and honours.

She will deliver two lectures at the UFS. The first is entitled A Potential Outcomes Approach to Documenting the Public Health Impact of the Introduction of PCV13 for the Prevention of Invasive Pneumococcal Disease. The topic of her second lecture is: Assessing the Effectiveness of Intrapartum Antibiotic Prophylaxis for Prevention of Early-Onset Group B Streptococcus Disease through Propensity Score Design

Elizabeth’s lectures will take place on:
Date: Wednesday 9 December 2015
Time: 10:45 and 13:00
Venue: West Block 111, Bloemfontein Campus
