Ebeth Grobbelaar is a Scientific Manager in the South African Doping Control Laboratory (SADoCoL) who is responsible for the review and approval of results at SADoCoL, to ensure compliance with the technical requirements of the World Anti-Doping Agency (WADA).

For Ebeth Grobbelaar, Scientific Manager in the South African Doping Control Laboratory (SADoCoL) – which is housed by the University of the Free State (UFS) – her work at the laboratory is profound, as fairness on and off the playing field is vital to her.

“Creating a fair playing field for athletes to compete carries a heavy responsibility, as an anti-doping violation impacts the athlete’s career,” says Grobbelaar, who is responsible for the review and approval of results at SADoCoL to ensure compliance with the technical requirements of the World Anti-Doping Agency (WADA).

Women are the cogs in the wheel

According to her, anabolic steroids, the multiple analytical disciplines, and rapidly changing technical requirements from WADA have attracted her to the sciences of anti-doping. Sixty percent of her colleagues at SADoCoL are women.  “They are the cogs in the wheel, ensuring the laboratory's smooth operation, taking daily challenges in their stride, and excelling in what they do as analysts and administrative staff,” says Grobbelaar.

Grobbelaar says there are many options in the anti-doping field for women inside and outside of the laboratory. Some of the most influential people in the anti-doping community are women – in their roles as laboratory directors, leading researchers, directors of athlete passport management units for international sports federations, or national anti-doping agencies in various capacities.

With all the responsibilities, come challenges and pressure – especially in a year when the Olympic Games take place. 

Women should learn how to say ‘no’ 

“An Olympic year always has additional stress due to the large number of samples before the games. This year, the pressure is more, with not all accredited laboratories operational, as well as disrupted testing schedules due to COVID-19.  Enabling athletes to compete in fairness on the world stage is a responsibility and a privilege.”

“My faith is my anchor.  As far as possible, I try to leave my work behind when I leave the laboratory, and concentrate on enjoyable things such as gardening, my dog, reading, and walking with my dog. On challenging days, something sweet also helps,” explains Grobbelaar the pressure and how she copes with it. 

This Women’s Month, Grobbelaar says, women should learn how to say ‘no’ to create time for rest and play. Says Grobbelaar: “For many women, ‘doing your best’ or saying yes means working yourself to the point of a mental and physical breakdown. Having the courage to say no, loving oneself through rest and play, replenishing our spirits, and realising that we are unique and precious in God’s eyes, is a challenge that many women face.” 

“Rest and play can take different forms, such as having coffee with a friend or being creative.  The important thing is that your rest or play activity brings joy to your soul and energises you. Ask your friends to support and assist you,” she concludes.

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
