Prof Atangana
Prof Abdon Atangana, a professor of Applied Mathematics at the University of the Free State (UFS), is the highest-ranked UFS scientist included in Stanford University’s World’s Top 2% Scientists list.

A professor of Applied Mathematics at the University of the Free State (UFS) is again the highest-ranked scientist from the institution included in Stanford University’s annual ranking of the top 2% of scientists in the world. 

Prof Abdon Atangana from the UFS’s Institute for Groundwater is ranked number one in applied mathematics, mathematical physics, mathematics, and statistics in the world, and number 260 in all of science, technology, and engineering in the Stanford University World’s Top 2% Scientists list. He is also ranked highest (5 620) of all the UFS scientists included in the career-long data set. 

‘Africans in Africa can impact the world’

“The ranking provides us with the impact of our outputs, and it shows that Africans can contribute to the development of science, technology, engineering, and mathematics while still in Africa,” Prof Atangana said. “This also shows that Africans in Africa can have impact on the world. My motivation is to tell the next generation that Africans do not always need to graduate from the top universities of the global North to make a global impact.  

“We must work hard to make our African universities reach the same level of those from the global North, such that a student from the global North will wish to enroll in our universities. The development of our continent does not rest on sport, music, and so forth alone, but on science, technology, engineering, and mathematics. Having the best scientists, mathematicians, and engineers in the world in Africa should be the strive of all Africans.” 

Three of the UFS’s SARChI Research Chairs have also been included in this list: Prof Hendrik Swart, Chair: Solid-state Luminescent and Advanced Materials (Applied Physics, ranked 40 269 in the single-year dataset); Prof Melanie Walker, Chair: Higher Education and Human Development (ranked 68 337); and Prof Maryke Labuschagne, Chair: Disease Resistance and Quality in Field Crops (Plant Sciences, 165 780).  

Other UFS scientists included in the single-year data set are: Prof John M. Carranza (Geology, 4 837); Prof Muhammad Altaf Khan ( Applied Mathematics, 6 366); Prof Maxim Finkelstein (Statistics/ Mathematical Statistics, 63 394); Prof Marianne Reid (School of Nursing, 72 861); Prof John Owen (Centre for Development Support, 103 368); Prof Brownhilder Neneh (Department of Business Management, 73 635); Prof Jorma Hölsä (Research Fellow: Department of Physics, 88 833); Prof Johann Beukes (Philosophy & Classics, 6 547 764); Rian Venter, (829 709); Dr Yuri Marusik (Zoology and Entomology, 553 619); Prof Robert Schall (Department of Mathematical Statistics and Actuarial Science, 276 681); Prof Deborah Posel (Department of Sociology, 275 535); Dr Vijay Kumar (Physics, 274 541); Dr Abhay Prakash Mishra (Pharmacology, 229 625); Prof RE Kroon (Physics, 226 554); Dr Krishnan Anand (Chemical Pathology, 235 300); Prof Andrew Marston (Chemistry, 147 147); Dr Seda Igret Araz (Applied Mathematics,125 824); Prof Jeanet Conradie (Chemistry, 106 521); Prof Louis Scott (Plant Sciences, 73 874); Prof Johan Grobbelaar (Plant Sciences, 97 722); Prof David Motaung (Physics, 53 553); Dr Samuel Nambile Cumber (Health Systems Research and Development, 555 563). 

Career-long data set 

The Stanford University rankings also include a list of the top 2% of world-class researchers based on citations over their full careers. Scientists are classified into 22 scientific fields and 174 sub-fields. Field- and subfield-specific percentiles are also provided for all scientists with at least five published papers. Career-long data is updated to the end of 2021, and single recent-year data pertain to citations received during calendar year 2021. The selection is based on the top 100 000 scientists by C-score (with and without self-citations) or a percentile rank of 2% or above in the sub-field.

The career-long data set includes the names of:

Prof Carranza (17 466); Prof Scott (55 882); Prof Reid (57 173); Prof Hölsä (64 402); Prof Grobbelaar (71 094); Prof Walker (78 239); Prof Andrew Marston (Chemistry, 84 484); Prof Schall (90 268); HA Snyman (Animal, Wildlife and Grassland Sciences, 96 374); Prof Swart (103 895); Robert WM Frater Cardiovascular Research Centre (111 896); Prof Frederick Kruger (Centre for Environmental Management,117 971); Prof Finkelstein (124 118); Prof Johan Visser (Geology, 125 331); Prof James C du Preez (Biotechnology, 168 841); Prof Posel (172 295); Prof Conradie (178 157); Prof Michael D MacNeil (Dairy and Animal Science, 184 193); Prof Khan (201 101); Prof Owen (262 897). 

“The representation of our researchers from a variety of disciplinary domains in this prestigious ranking, is confirmation of their excellence, impact, and the global esteem they hold. UFS is proud to be a home to scholars in our midst who take us incrementally forward as an institution because of their cutting-edge research,” said Prof Vasu Reddy, UFS Deputy Vice-Chancellor: Research and Internationalisation. 

  • Prof Atangana has also been shortlisted as one of the finalists for the prestigious Alkebulan Immigrants Impact Awards (AIIA) 2023, in the South African Flag Carrier category. Voting started on 1 November, and the award ceremony is set to take place on 23 November in Johannesburg.

From music to theology: Stats Unit valuable in research process

Whether it is analysing data on church attendance, climate change in the Northern Cape or injuries among elite female hockey players, the Statistical Consultation Unit at the University of the Free State (UFS) can assist researchers from the planning of research to publication therof.

Many students and researchers think that the time to consult a statistician is after their research data has been collected. According to Prof Robert Schall, head of the unit, the most significant contribution a statistician can make to a research project is often during its planning. Preferably all researchers should consult the unit early in the research process.

Statistical consultation service free for postgraduates
The consultation unit, established in 2014 in the Department of Mathematical Statistics and Actuarial Science, provides support to all UFS researchers. This service is rendered to postgraduate students at no charge.

“The unit can make a contribution throughout the research process, from the planning of the research project, through the analysis of research data, up to the publication of the findings. I have been involved in projects where, for example, a few very simple changes to the design of a questionnaire would have saved the researcher and the statistician a lot of trouble. It will be beneficial for researchers to have their questionnaires and study proposals (where relevant), reviewed by a statistician,” Prof Schall said.

“The unit can make a contribution
throughout the research process,
from the planning of the research
project, through the analysis of
research data, up to the publication
of the findings.”

Fascinating research topics deliver fascinating data
The professor assisted in a study for the Department of Soil, Crop and Climate Sciences to determine whether rainfall in the Northern Cape had changed over the past 90 years, potentially indicating climate change.

Other interesting projects he has worked on came from the Department of Exercise and Sport Sciences. “Who will not be fascinated by data sets on aspects of rugby, cricket or even netball? One significant finding was a predictor of injury in elite female hockey players. The PhD student identified a pre-season test which predicted the occurrence of an in-season injury with 100% specificity and 100% sensitivity. The finding was quite surprising, and, if the results can be replicated, obviously would be useful in the prevention of injuries,” he said.

This is, of course, not an exhaustive list of projects the unit has worked on. “Not in my wildest dreams would I have expected to be involved in projects coming from the Faculty of Theology, or from the Odeion School of Music,” Prof Schall said.
