UFS professor recognised as one of Africa exceptional young scientists Prof Abdon Atangana
Prof Abdon Atangana is from the University of the Free State’s Institute for Groundwater Studies.
Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies was recently announced by the African Academy of Sciences (AAS) as one of 25 early career scientists who were elected to form part of the third cohort of the AAS Affiliates Programme, which recognises exceptional young African scientists.

The Affiliates will be part of the AAS membership pool from 2018 to 2022, during which time they will be supported to attend conferences, symposia and workshops and other activities that will improve their skills in proposal development, grant writing and pitching innovations to help them win more grants, improve their publication records and ensure that their research impacts their communities.

Brilliant minds
“We welcome the new cohort that represents some of the brilliant minds from the continent. The AAS is committed to ensuring that they are provided with the opportunities they need to develop their careers and contribute to the development of the continent,” said AAS Executive Director Prof Nelson Torto.

The third cohort saw the most competitive pool yet with an overwhelming number of nominations from across the five regions of the continent of PhD holders below the age of 40. This year’s Affiliates are also drawn from countries not covered in the previous two cohorts including, Ethiopia, Senegal and Sierra Leone. Other countries from which the 25 were selected are Benin, Cameroon, Egypt, Ghana, Kenya, Nigeria, Tanzania, Tunisia, South Africa and Uganda.

Besides mathematical sciences, Affiliates also represent disciplines that include cultural sciences, humanities and social sciences, medical and health sciences, agricultural sciences, biosciences and geological, environmental, Earth and space sciences.

World class research leaders
The AAS is a pan-African organisation headquartered in Kenya, that aims to drive sustainable development in Africa through science, technology and innovation. The AAS set up the Affiliates programme in 2015 to recognise, mentor and help early career professionals develop into world-class research leaders.

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
