Prof Abdon Antangana
Prof Abdon Atangana, a Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS) and South Africa’s top-ranked scientist in Mathematics, wants to prepare the next generation of African professors.

A new book written by Prof Abdon Atangana, Professor of Applied Mathematics at the Institute for Groundwater Studies at the University of the Free State (UFS), in collaboration with one of his students, on the flow of groundwater, suggests several new and modified models to better predict anomalous behaviours of the flow and the movement of pollution within complex geological formations.

Mathematical Analysis of Groundwater Flow Models is one of two books Prof Atangana published recently that he wrote with his students. The other, Fractional Stochastic Differential Equations: Applications to Covid-19 Modeling, provides a thorough conversation on the underpinnings of COVID-19 spread modelling. He wrote the book with a postdoctoral fellow, Dr Seda Araz Igret from SIIRT University, Turkey. Since 2016 he has published a total number of six books, some of which are still under evaluation by Springer and Elsevier.

Time to prepare next generation of African professors 

This highly cited researcher is excited about collaborating with his students on projects such as these as he feels it is time for him to prepare the way for the next generation of African professors. Prof Atangana is ranked at No 219 in the world rankings and No 1 in South Africa by Research.com, a leading academic platform for researchers. 

According to the platform, which recently released the 2022 Edition of its Ranking of Top 1000 Scientists in the field of Mathematics, the ranking is based on the H-index metric provided by Microsoft Academic and includes only leading scientists with an H-index of at least 30 for academic publications in the field of Mathematics.

“Both books are important for me because they are first-time published books with my own students. There is a time to prepare the way for yourself and a time to prepare ways for the next generation. It is time for me to prepare the way for the next generation of African professors. I wish that the next time this list (https://research.com/scientists-rankings/mathematics/za) [is released] many of my students [will] appear,” says Prof Atangana.

About his book with Dr Igret, he says it presents the dynamic of COVID-19 spread behaviour worldwide. It is noticed that the spread dynamic followed process with nonlocal behaviours, which resemble power law, fading memory, crossover, and stochastic behaviours. Fractional stochastic differential equations are therefore used to model spread behaviours in different parts of the world. 

“The content coverage includes a brief history of COVID-19 spread worldwide from December 2019 to September 2021, followed by statistical analysis of collected data for infected, death and recovery classes,” says Prof Atangana.

Mathematical analysis of Groundwater Flow Models serves as a valuable resource for graduate and PhD students as well as researchers working within the field of groundwater modelling, says Prof Atangana. It includes features such as:
• Modified numerical and analytical methods for solving new and modified models for groundwater flow and transport 
• New flow and transform models for groundwater transport in complex geological formations 
• Examination of fractal and crossover behaviours and their mathematical formulations

Top-ranking scientist 

Prof Atangana was also recently elected as a fellow of The World Academy of Sciences (TWAS) and received the World Academy of Sciences Award for Mathematics (TWAS -Mohammad A Hamdan, 2020) on 1 November 2021.

Very recently, he was also ranked No 1 in the world in Mathematics, No 186 in the world in all the fields, and No 1 in Africa in all the fields, according to the Stanford list of 2% single-year table.

He was also named among the top 1% of scientists on the global Clarivate Web of Science list. Fewer than 6 200 or 0.1% of the world’s researchers were included on this list in 2019, 2020 and 2021, with fewer than 10 of the scientists hailing from South Africa. 

“While my name is ranked No 1 in South Africa and No 219 in the world, this shows the impact of my research that has been done since 2013. It is worth noting that this ranking disadvantages younger researchers. For example, I got my first publication in 2013 but the researcher who was ranked No 1 started in 1972. To make the ranking fair, the total H-index should be divided by the number of years of publication. I am very proud to see that despite this disadvantage I am still topping in South Africa and am No 219 in the world.”

Giraffe research broadcast on National Geographic channel
2016-03-09

Description: Giraffe research  Tags: Giraffe research

A documentary focusing on the latest and most interesting research about giraffes was recently broadcasted on National Geographic. Dr Francois Deacon from the UFS Department of Animal, Wildlife and Grassland Sciences and the team of researchers working with him, were first in the world to equip giraffes with GPS collars, and to conduct research on them.

Research by Dr Francois Deacon, from the UFS Department of Animal, Wildlife and Grassland Sciences, involving the equipping of giraffes with GPS collars, was broadcast this week as part of a documentary (4 March 2016 and subsequent weeks) on National Geographic (Channel 182). The documentary is the first of two on his team's research.

Dr Deacon and the team of researchers working with him were the first in the world to equip giraffes with GPS collars, and to conduct research on this initiative. The group of researchers can now follow the animals night and day by means of the GPS collars, while monitoring their movements from a distance on a computer screen and seeing the world from a giraffe's perspective.

“The documentary focuses on the latest and interesting information about our research in different countries,” Dr Deacon said. Besides their local research on giraffes, he and his team also assist in other projects and research in Namibia, Botswana, Zambia, Kenya, the Democratic Republic of the Congo, and Uganda.

“There is much to learn from the documentary,” Dr Deacon said. Interesting facts from their research include herd interactions by individuals towards each other, bulls versus bulls, and cows versus calves. In the documentary, the viewer can also learn how giraffes use thermoregulation, their tongues, and roaming areas and distances; peculiar behaviour such as feeding on bones and soil; bulls fighting; how and when giraffes drink water; and the conservation and management of giraffes.
 
Focus is also placed on the manner in which the latest research plays a role in the better understanding of the animals.
 
According to Dr Deacon, this is the first documentary to focus on giraffe research on such a large scale. Marco Polo Films from Terra Mater are contracted by National Geographic to produce nature films – this was the hundredth nature film produced by them.
 
“There has never before been such a production about giraffes. It also attracted huge interest and reaction overseas, which will provide great exposure for our research and for the UFS.
 
“We believe that the media involvement will provide much more exposure to giraffes, which is a good thing, since they are facing extinction in Africa. The exposure can, in itself, lead to new research and has already started attracting international students to the UFS,” Dr Deacon said.
 
The second documentary will follow later this year. Iniosante, a film team from Texas, USA, is producing this film, which focuses on the extinction of giraffes. It is the same team responsible for the production Last of the Longnecks.
