Prof Abdon Atangana was recently elected a fellow of The World Academy of Sciences (TWAS).

Prof Abdon Atangana, Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS), was recently elected a fellow of The World Academy of Sciences (TWAS).

He also received the World Academy of Sciences Award for Mathematics (TWAS -Mohammad A. Hamdan, 2020) on 1 November 2021.

TWAS, described as the voice for science in the South, is working towards the advancement of science in developing countries and supports sustainable prosperity through research, education, policy, and diplomacy. 

Outstanding contribution to science

Prof Mohamed HA Hassan, President of TWAS, congratulated Prof Atangana on this prestigious achievement, “Your election as fellow is a clear recognition of your outstanding contribution to science and its promotion in the developing world. We will be honoured to have you among our members.”

Candidates elected as TWAS Fellows are scientists whose contributions to their respective fields of science meet internationally accepted standards of excellence, and they must have distinguished themselves in efforts to promote science in developing countries. 

Prof Atangana is known for his research to develop a new fractional operator, the Atangana-Baleanu operator, which is to model real-world problems. With this operator, he not only describes the rate at which something will change, but also account for disrupting factors that will help to produce better projections.

Among others, his models can advise people drilling for water by predicting how groundwater is flowing in a complex geological formation. Furthermore, his work can also be applied to predict the spread of infectious diseases among people in a settlement, forecasting the number of people who will be infected each day, the number of people who will recover, and the number of people who will die. 

These are only two examples of how his work can be applied to better the lives of people.

Promoting science in the developing world

Besides promoting science in the developing world, Prof Atangana’s work also contributes to the United Nations Sustainable Development Goals – the global goals as set in 2015 that call for ending poverty, protecting the planet, and ensuring that all people enjoy prosperity and peace.

Prof Atangana says the election as fellow is a clear recognition of his outstanding contribution to science and its promotion in the developing world. “My work over the past five years has made a great impact in all fields of science, technology, and engineering.”

To be elected as TWAS fellow in mathematics, made him the second South African researcher to be elected in the field of mathematics (the first person elected was Prof Reddy Batmanathan Dayanand, who was elected in 2003). This also placed him as the sixth African mathematician to be elected as a TWAS fellow.

Very recently, he also ranked number one in the world in mathematics, number 186 in the world in all the fields, and number one 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. Less than 6 200 or 0,1% of the world's researchers were included on this list in 2020, with no more than 10 of the scientists hailing from South Africa. 

Prof Atangana is also editor of more than 20 top-tier journals of applied mathematics and mathematics, and for some of these journals he was the first African to be selected as editor.

UFS mourns the passing away of Prof. Leo Barnard
2009-04-02

It is with sadness that the management of the University of the Free State (UFS) heard about the death of Prof. Leo Barnard. He passed away yesterday afternoon in the George Medi-Clinic as a result of cancer.

Prof. Barnard was associated with the UFS for many years and was Head of the university’s Department of History from 1997–2008. He was appointed as research associate at the department after his retirement last year.

“Prof. Barnard was one of the few military historicists in South Africa. He was amongst others a member of the South African Historical Society and also served on several professional organisations such as The South African Academy for Science and Arts,” said Prof. André Wessels, Head of the Department of History at the UFS.

He served on the editorial committee of the Journal for Contemporary History, an accredited academic journal published by the Department of History at the UFS. He was editor of this journal for ten years. “Prof. Barnard played an important role in the development of the journal, especially in the publishing of special editions. When he passed away, he was working on the latest edition of the journal, which deals with the so-called border war,” said Prof. Wessels.

Prof. Barnard was especially well-known for his mentorship to Master’s and Doctoral students. “At the time of his death he was still providing guidance to students,” said Prof. Wessels.

Prof. Barnard did a lot of research and writing for the UFS’s centenary publication, From Grey to Gold – The first 100 years of the University of the Free State.

“We also sympathise with Mrs Renaldine Barnard and the couple’s four daughters, Eda, Arina, Leona and Elfrieda, their two sons in law and one grandchild. Prof. Barnard has left a gap in the hearts of the people who knew and worked with him at the UFS,” said Prof. Wessels.

The memorial service will be held on Friday, 3 April 2009 in the community hall of Vleesbaai in the Western Cape.
