Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics, shares his UFS journey.

The University of the Free State (UFS) is celebrating Youth Month by showcasing the positive influence of the institution on career development. As part of this initiative, we are sharing the stories of UFS alumni who are now working at the university.

Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics, shares his UFS journey:

Q: Year of graduation from the UFS: 

A: 2004 and 2015.

Q: Qualification obtained from the UFS: 

A: BSc in Physics and Mathematics and PhD in Solid State Physics.

Q: Date of joining the UFS as a staff member: 

A: 2003 to 2004 and 2012 to date.

Q: Initial job title and current job title: 

A: I began my journey as a Lab Assistant, but over time, I advanced to higher positions within the academic realm. Presently, I proudly serve as a Senior Lecturer and Subject Head in the esteemed Department of Physics. Additionally, I have taken on the role of acting Assistant Dean in the distinguished Faculty of Natural and Agricultural Sciences.

Q: How did the UFS prepare you for the professional world? 

A: First and foremost, I successfully completed my BSc degree, followed by the attainment of a Doctor of Philosophy (PhD). I firmly believe that these educational achievements serve as a solid foundation for excelling in both teaching and leadership roles.

Q: What are your thoughts on transitioning from a UFS alumnus to a staff member? 

A: It is a very interesting aspect; however, this transition may entirely depend on an individual’s interest in whether to continue with their studies or not. The stimulation may come from the undergraduate teachings that exhibit real interventions for new developments towards empowering the society at large.

Q: Any additional comments about your experience? 
A: As both an academic and a departmental leader for the past nine years, I am very grateful for all the support from the university community. I would encourage young scholars to explore more leadership roles that are available in the sector, because one is always up to date with new initiatives and strategies for the betterment of human and academic projects.

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.
