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.”

Award-winning architect firm presents the 29th Sophia Gray Memorial Lecture and Exhibition

The laureates of this year’s Sophia Gray Memorial Lecture were George Elphick and Nicholas Proome from the award-winning architecture firm, Elphick Proome Architects (EPA). Over the past 28 years this Durban firm has received 26 awards and its work has been published in 26 magazines.  

From bedroom to boardroom
EPA is involved in major corporate architecture as well as several residential projects. It believes that good design is produced from careful study and research combined with sound technical knowledge and artistic judgement. At the 29th Sophia Gray lecture, presented by the Department of Architecture at the University of the Free State, EPA addressed the Bloemfontein community, stating that architecture was about people, space and light. 

For EPA, architecture is the form of art with the most impact on society. “Ultimately, our architecture needs to be enjoyed and be hard to forget,” it said. 

In its three decades of practice, most of EPA’s built work has been executed in South Africa. It has also completed projects beyond South African borders, including Mozambique, Kenya, Ghana, and France. 

The lecture was followed by the opening of the 29th Sophia Gray Memorial Exhibition at Oliewenhuis Art Museum.

New PhD in Architecture with Design announced
A highlight at this year’s lecture was the announcement by Henry Pretorius, the head of the department, of a new and innovative doctoral programme, the PhD in Architecture with Design. From 2018, students with a MArch (professional) or MArch can enrol for this postgraduate qualification.

“The programme recognises the intelligence and ingenuity of design. Its primary objective is to harvest and study the implicit orientations, operations, and achievements of design, and to enlist creativity in the formation of new knowledge. The degree facilitates analytical reflection, stimulates creative action, and opens new insights into the unique logic of design,” said Pretorius.

“Although design-based research has gained international momentum in recent years, similar research has not been done in South Africa until now.”

Contribution to the Sophia Gray Bursary Fund 
During a breakfast function, the department also announced another initiative, the Sophia Gray Bursary Fund. Prof Francis Petersen, Rector and Vice-Chancellor at the UFS, said that the type of architecture in developing countries was different from places such as New York and other big cities in developed countries. For a transformed profession we need architects from different cultures and demographics in the system. The bursary fund was a fantastic starting point for this to happen. 

The Sophia Gray Bursary Fund initiative is part of a greater call to alumni and friends of the department to be actively involved in the department’s continuous development and future endeavours towards imagination, care, and excellence.
AJ Corbett, founder and director of TCN Architects in East London, made the first contribution towards the fund.
