Dr Francois Jacobs
Dr Francois Jacobs received his Doctor of Philosophy degree in Chemistry on Monday, 9 December.

Dr Francois Jacobs, a 30-year-old PhD graduate, has recently returned from an intensive training workshop in Harwell, Oxford, courtesy of the David Blow Bursary. This prestigious award recognises outstanding African researchers making significant contributions to macromolecular crystallography.

Dr Jacobs earned his Doctor of Philosophy degree in Chemistry on Monday, 9 December. While earning a PhD by the age of 30 was not part of his initial plan, he always aspired to pursue higher education. “From a young age, I had a strong desire to study at university. Once I got there, my ambition shifted towards obtaining a PhD,” he says, reflecting on the journey that led to this remarkable achievement.

Groundbreaking research on cancer and antibiotics

Dr Jacobs’ research addresses some of the most pressing health challenges of our time: cancer and antibiotic resistance. Using crystallography, he investigates the interactions between newly developed anticancer and antibacterial compounds and biological structures such as proteins at the atomic level. This work is vital in combating the growing threat of antibiotic-resistant bacterial infections and advancing cancer treatments.

"For me, it's about seeing humans thrive and reducing the suffering caused by illness," he explains. "I lost my grandmother to cancer, and I hope my work can spare someone else’s loved one from a similar loss."

Prestigious workshop with global experts

The "DLS-CCP4 Data Collection and Structure Solution Workshop," hosted by Diamond Light Source, offered Dr Jacobs an unparalleled opportunity to learn from leading experts in macromolecular crystallography. The workshop covered critical skills such as growing protein and DNA crystals, preventing degradation during data collection, and processing complex data. Participants also gained insights directly from the engineers and scientists behind the facility’s cutting-edge software and synchrotron technology.

“It was an incredible opportunity to learn from some of the brightest minds in the field,” says Dr Jacobs. “Not only did I acquire new skills, but I also forged new collaborations with potential research partners who can help take my work to the next level.”

The David Blow Bursary, which enabled Dr Jacobs to attend this workshop, is awarded to  African researchers conducting impactful macromolecular crystallography studies.

"This training has been transformative," he adds. "It is a fantastic experience for any aspiring researcher, and I’m grateful to have had the chance to learn from these experts. Many researchers who attend workshops like this go on to work at the Diamond Light Source itself. I am eager to see where this training will take me."

A vision for the future

As Dr Jacobs continues his research, he remains driven by the hope that his work will lead to life-saving advancements in healthcare. “I want my research to provide hope and solutions for individuals battling cancer and bacterial infections,” he says.

His achievements exemplify the transformative power of education, research, and collaboration, and his story serves as an inspiration to aspiring researchers across Africa.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
