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.”

#Women’sMonth: A career in Sign Language interpreting proves to be full of rewards for Natasha Parkins-Maliko

Natasha Parkins-Maliko is an alumna of the University of the Free State who graduated with a master’s in Linguistics. She is a well-rounded interpreter with a language combination of South African Sign Language-English-Afrikaans. She continued her studies and achieved an international master’s in Sign Language interpreting at the Humak University of Applied Sciences in Finland.  Natasha was recently presented with the Pansalb Multilingual Award in the category: Translation and Interpreting 2016/2017, as recognition for her achievements in a sixteen-year career.

“Winning the Pansalb Translation and Interpreting Award for 2016/2017, was for me as Kovsie a pat on the back in the true sense of the word.  The university is where I started my journey in South African Sign Language interpreting, and from then on, I never looked back,” she said.

Her interpreting career has provided many challenges, and was accompanied by great achievements along the way.

A career of fulfilment in Sign Language

“The foundation of my success was laid by my lecturers and mentors, such as Dr Philemon Akach and Emily Matabane, where I trained in the Department of South African Sign Language (SASL) at the university.”

“My determination and success is grounded in the motto, ‘Inspiring Excellence, Transforming Lives’ – a continued journey in excellence gives a renewed sense of pride for all language practitioners in South Africa,” she said.

Natasha went on to work in the deaf community for most of her career. She started as a grassroots interpreter, and is now a professional interpreter registered with SATI (South African Translators Institute). She is also a Sign Language television interpreter on SABC for content such as SABC 3 news bulletins, the budget speech, opening of Parliament, Youth Day broadcasts, January 8th statement broadcasts, MPC Reserve Bank speeches, and many more. Natasha is not only concerned with growing her career – despite her mover and shaker persona, she still takes time to volunteer her services for deaf people who do not have the financial ability to pay for interpreting.

“Winning the Pansalb Translation and
Interpreting Award for 2016/2017, was
for me as Kovsie a pat on the back in
the true sense of the word.”

The journey to excellence never stops
Over and above lecturing in Interpreting and Translation at Wits University, Natasha is still in pursuit of excellence. She is a PhD candidate in the SASL Interpreting programme at Wits University, the first of its kind in the country, and is pursuing an AIIC (International Association of Conference Interpreters) accreditation. Her aim is to put South African Sign Language interpretation on the global map.

As a role model and icon in her field, Natasha is the chairperson of the National Association of South African Sign Language Interpreters (NASASLI), the regional coordinator for the African Federation of Sign Language Interpreters (AFSLI), and the Africa regional representative on the board of the World Association of Sign Language Interpreters (WASLI).  The award presented to her is no doubt a fitting accolade and something all UFS alumni takes pride in.
