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.”

“My time at the UFS was the golden gem of my career”

“My time at the University of the Free State (UFS) was the golden gem of my career. I have worked at medical schools or biomedical research centres in the United Kingdom, United States and at some of the top medical schools in South Africa, but working at the UFS was one of the highlights of my career,” says Prof Alan St Clair Gibson, Head of the UFS School of Medicine.

After spending just over two years at the UFS, Prof St Clair Gibson resigned from the institution in June 2016 and will take up the position of Dean: Health and Human Performance Sciences at the Waikato University in New Zealand in mid-July, where he will assist to establish a new faculty for all the health-science disciplines. “It was a privilege to work at the UFS. I come from a strong research background and wanted to grow research at the university, which I achieved. I came to the UFS because of the Academic and Human Projects and am proud of what has been achieved at the School of Medicine during the time I was here,” he said.

Prof St Clair Gibson highlighted some of these achievements, including the development of a management infrastructure across the disciplines of the school. “The establishment of an executive management committee for the school, as well as research champions in departments, highlighted the importance of proper governance and strategic management. By developing data dashboards, my management team and I could develop an understanding of research income and productivity, how the school works, what the role of teaching and learning is, and how the school could benefit in terms of third-stream income from the many contracts obtained by its academic staff. As a result, contracts and the financial management model of the school have also been reconfigured to the benefit of the university so that the institution and school can benefit from it,” he said.

His strong belief in an open-door policy has made staff feel part of the environment and it has created an atmosphere of equality and inclusivity. He believes in staff development and has, for instance, established leadership and management courses for heads of departments. Another factor to be proud of is the increase in the number of young researchers who recently joined the school, such as Prof Ross Tucker, who is one of the foremost sport scientists in the country. “It is a fact that staff retire or resign in all schools and departments of any university. It is also true that these departures offer opportunities to bring new academic and professional staff into the UFS. In fact, for the first time virtually every department in the School of Medicine now has a full-time Head of Department and 46 new staff were appointed since January 2015,” said Prof St Clair Gibson.

“I am especially proud of contributing, together with the senior leadership of the UFS, to stabilise the relationship with the Free State Department of Health (DoH). With the assistance of these parties, as well as my executive management team, we could find a better way of working together to the benefit of the school and the province.’’

Transforming the student profile to be representative of the country’s demographics is another milestone Prof St Clair Gibson will remember. “The intake of black and white students is of such a nature that we now have a much more balanced ratio of black and white undergraduate students than before.”

“I wanted to stay longer to see the effect of all the changes I made at the school, but the deanship is an offer I cannot refuse. I would have liked to see a steadier increase in the number of permanent clinical staff and have worked hard with both the UFS management and the DoH to try and achieve that; but more work needs to be done.”

I have worked with a number of fantastic staff members at the school, who are determined to do good in a challenging environment. I am amazed at the energy of the university leadership and how the Human and Academic Projects are executed. My wish for the university is to maintain and grow its standards and for the School of Medicine to maintain its reputation as one of the best schools in the country. I will always be a proud alumnus of the UFS,” he said.
