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).

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.

Prof Melanie Walker, Chair: Higher Education and Human Development, is ranked 68 337 in the single-year data set.

Prof Brownhilder Neneh, from the Department of Business Management and Vice-Dean for Research Engagement and Internationalisation, is ranked 73 635.

Prof Marianne Reid from the School of Nursing is ranked 72 861.

Research on locomotion of giraffes valuable for conservation of this species

approximately 20 - 30 m away. When the
drone moves closer, they will revert
to galloping.

The meaning of the Arab term Giraffe Camelopardalis is ‘someone who walks fast’. It is precisely this locomotion of their longnecks that encouraged researchers, Dr Francois Deacon and Dr Chris Basu, to study the animals more closely.

Despite the fact that giraffes are such well-known animals, very little research has been done on the manner in which these graceful animals locomote from one place to the next. There are only two known ways of locomotion: the slower lateral walking and the faster galloping. Most animals use these ways of moving forward. It is unknown why giraffes avoid intermediate-speed trotting.

Research of great value to the industry
Research on the manner in which giraffes locomote from one place to the next will assist the industry in understanding aspects such as their anatomy and function, as well as the energy they utilise in locomoting from one place to another. Information on the latter could help researchers understand where giraffes fit into the ecosystem. This data is of great value for large-scale conservation efforts.

Universities working together to collect data
Dr Basu, a veterinarian at the Royal Veterinary College in the UK, has studied the animals at a zoo park in the United Kingdom. He visited the University of the Free State (UFS) in order to expand his fieldwork on the locomotion of giraffes. This study was done in cooperation with Dr Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research in South Africa and other African countries.

The fieldwork for the research, which was done in the Woodland Hills Wildlife Estate and the Willem Pretorius Nature Reserve, preceded research on the movement and the forces involved in the locomotion of giraffes. Due to the confined fenced area in the zoo park, it was practically impossible to study the animals at speed. “The study of actions ‘faster than walking’ is crucial for gathering data on, inter alia, the frequency, length, and time associated with each step.

Technology such as drones offers unique
opportunities to study animals like giraffes.

Technology used to ensure accuracyTechnology such as drones offers unique opportunities to study animals like giraffes. Apart from the fact that it is possible to get high-quality video material of giraffes – moving at speed – it is also a very controlled device that ensures the accuracy of data.

It is the first time ever that a study has been done on the locomotion of giraffes with this level of detail.
Research on the study will be published in the Journal of Experimental Biology.

The project was approved by the UFS ethics committee.
