Corlé van der Walt received her honours degree in mathematics and applied mathematics. She wants to show students that mathematics is not necessarily difficult, but that it is logical and practical.

Mathematics is undeniably part of the world – from telling time, buying groceries, to manufacturing clothing sizes, and everything in between.

This is the view of Corlé van der Walt, Junior Lecturer in the Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), who received her honours degree in mathematics and applied mathematics (with distinction) at the university’s April 2023 graduation ceremonies. 

The focus of her honours was on applied mathematics, specifically optimisation and dynamical systems. “These subjects link to my undergraduate degree, which is in industrial engineering,” says Van der Walt, who has always enjoyed and excelled in mathematics for as long as she can remember. 

Maths = skills +

She believes that mathematics is important because it helps us describe and value ourselves. “But still, mathematics is more than just the skills we learn; in the words of Albert Einstein, "Mathematics is, in its way, the poetry of logical ideas".

She says that mathematics is also the foundation for other sciences, such as physics, chemistry, and engineering. “Mathematics paves the way for all other forms of science. Without the computational groundwork, it will not be possible to do physics, chemistry, engineering, or any other form of science,” she adds, remarking that we will not be able to make scientific or technological progress.

“This is where I come in; I want to teach young upcoming students’ mathematics and the power of it. I want to show students that mathematics is not necessarily difficult, but that it is logical and practical. With my current qualification, I have already been appointed as a junior lecturer and I teach precalculus to university students who would like to take calculus,” she says.

A balancing act

Although she enjoys her work, Van der Walt finds it challenging to juggle work and studies. But she overcomes these obstacles by prioritising tasks and celebrating small achievements. Her motivation also comes from the joy of seeing her students understand concepts that they previously struggled with. 

With plans to complete her master's degree in the next two years and commencing her PhD studies, Van der Walt is committed to teaching the power of mathematics to upcoming students.

Ethiopia is one of the African countries, deeply affected by food insecurity. Berhanu Tadesse Ertiro, a citizen from Ethiopia started his career - after graduating with his undergraduate degree in 2003 - as a junior maize breeder. Today he is pursuing his doctorate degree in Plant Breeding at the University of the Free State (UFS).

His research had made some great strides in contributing to food security in Africa. He recently received a fellowship from the prestigious Norman E. Borlaug Leadership Enhancement in Agriculture Program (Borlaug LEAP).

This fellowship is only awarded to students whose research has relevance to the national development of the student’s home country or region. The aim of these fellowships are to enhance the quality of thesis research of graduate students from developing countries who show strong promise as leaders in the field of agriculture and related disciplines.

Low soil fertility a major maize production constraint
Berhanu is also a visiting student at the International Maize and Wheat Improvement Center (CIMMYT) in Kenya, where he is running field experiments for his PhD thesis dissertation. His research focuses on Nitrogen Use Efficiency (NUE) and Maize Lethal Necrosis (MLN) disease tolerance. Low soil fertility and MLN are among the major maize production constraints in eastern and southern Africa, where maize is staple food.

Such hybrids have the potential to contribute greatly
towards food security among farmers and their
families through increased productivity.

The use of new tools could increase breeding efficiency and reduce the time needed for the release of new stress tolerant hybrids. Such hybrids have the potential to contribute greatly towards food security among farmers and their families through increased productivity. Berhanu is looking at the feasibility of genome wide selection for improvement of NUE in tropical maize.

Fellowship includes mentorship and supervision across borders
The programme supports engaging a mentor at a United States university and Consortium of International Agricultural Research Centers (CGIAR). During his fellowship, he will be supervised and mentored by Prof Maryke Labuschagne of the UFS, Prof Rex Bernando, a professor of Corn Breeding and Genetics at the University of Minnesota and Dr Biswanath Das of CIMMYT, Kenya.

As a LEAP fellow, Berhanu was invited to attend the 30th Annual World Food Prize events to take place in October 2016, in Des Moines, Iowa. The week will include his attendance at the Board for International Food and Agricultural Development meeting, participation at side-events at the Borlaug Dialogue International Symposium and the World Food Prize.
