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.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
