Prof Abdon Atangana, leading applied mathematics scholar at the University of the Free State, who has been awarded the Chevalier de l’Ordre de la Valeur by the President of Cameroon in recognition of his outstanding contributions to science and international academic engagement.

In recognition of his exceptional contributions to science and for promoting a positive image of Cameroon internationally, Prof Abdon Atangana, a leading professor of applied mathematics at the University of the Free State (UFS), has been awarded one of the country’s highest national honours by His Excellency President Paul Biya.

Prof Atangana, who is based in the UFS Faculty of Natural and Agricultural Sciences, was formally informed by the Cameroon High Commission in Pretoria that the President had decided to confer upon him the title Chevalier de l’Ordre de la Valeur (Knight of the Order of Valour).

“I am deeply honoured by this recognition and grateful to the High Commission for conveying the news,” said Prof Atangana.

The Ordre de la Valeur is one of Cameroon’s principal national distinctions, awarded to individuals who have rendered distinguished service or made significant contributions in fields such as science, public service, the arts, or international representation.

“The title Chevalier denotes formal national recognition by the President,” Prof Atangana explained. “It affirms the value of my work and encourages continued research, mentorship, and international collaboration.”

 

A career of global impact and recognition

Prof Atangana’s career is marked by both academic excellence and international engagement. He has consistently ranked among the top 1-2% of applied mathematicians worldwide, according to Stanford University’s global list. His achievements include being the first African mathematician under 40 to become a Fellow of the African Academy of Sciences Affiliates, receiving the UNESCO–TWAS Mohammad A. Hamdan Prize, the AL Fozan UNESCO Award for STEM, and the African Genius Award.

He also serves as Chair of the African Mathematical Union Commission on Research and Innovation and is the first President of the African Society for Industrial and Applied Mathematics (ASIAM).

In a historic milestone for African mathematics, Prof Atangana represented Africa for the first time at the Board Meeting of the International Council for Industrial and Applied Mathematics (ICIAM) in Vietnam in 2025. This prestigious gathering brings together presidents of national and international applied mathematics societies, including the President of the International Mathematical Union, and marks a significant recognition of his leadership on the global stage. 

“Being named Chevalier de l’Ordre de la Valeur recognises years of sustained work and the support of many colleagues and students,” he said. “Professionally, it is an important encouragement to continue my research, mentoring, and international engagement.”

Beyond awards, Prof Atangana has actively promoted Cameroon’s profile in the international scientific community. He has built high-impact research collaborations, supervised and mentored students from Cameroon and across Africa, presented at international conferences, and published research connecting African science with global knowledge networks.

 

Advancing science through the UFS and international collaboration

Much of the work recognised by this honour has been conducted at the University of the Free State.

“The recognition reflects the outcomes of work done at the UFS and signals the university’s contribution to advancing regional research capacity and international partnership,” Prof Atangana said.

His academic engagement in South Africa has enabled him to act as a bridge between institutions, fostering joint research, student exchanges, and collaboration across continents. These activities demonstrate the power of academic engagement in promoting scientific excellence and strengthening international networks.

Looking ahead, Prof Atangana plans to leverage this recognition to expand collaborative research projects, create more opportunities for student exchanges and mentorship, and advance interdisciplinary initiatives addressing regional and global challenges.

“I will continue to promote the value of academic engagement in service of shared scientific and societal goals,” he said. “This recognition will inspire me to strengthen collaborative networks, pursue joint research initiatives, and mentor the next generation of researchers.”

Details of the official medal award ceremony will be shared by the Cameroon High Commission in due course.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
