Dr Ocaya
Dr Richard Ocaya’s research addresses the skills development and transfer millennium goal of many governments globally.

With the Fourth Industrial Revolution becoming a reality, Dr Richard Ocaya’s research is receptive to the fact that Africa and the world need to re-imagine their research. His research focuses on electronic instrumentation design for scientific measurements, computational physics on atomic nano-atomic structures, and semiconducting organic compounds materials built on silicon to realise Schottky devices.

Software developer 
“I develop most of the instrumentation that I apply in my research – both software and hardware,” said Dr Ocaya, a Physics Lecturer and Programme Director: Physics and Chemistry on the UFS Qwaqwa Campus.

“I am active in scientific computing through the computing cluster and software development, mathematical physics for material science modelling, and embedded instrumentation design using microprocessors. I also have deep interest in radio and data telemetry, in which I hold a South African patent issued in 2013. My present international collaborations are with like-minded researchers in similar fields in Saudi Arabia, Turkey, Japan, Egypt, South Korea, and the United States,” he added.

How does his research talk to the real world?
“The driving principle of all areas of my research has always been to deploy cutting-edge research to actual, real-world applications for the immediate betterment of Africans. The areas of my research align closely with the millennium goals of many governments globally, including the Republic of South Africa. These goals pertain to skills development and transfer that position us to better address the challenges of energy, water, and other priorities.”

Dr Ocaya is currently co-promoting a PhD student, having previously supervised one PhD, two MSc, and more than twenty honours students. He is a self-taught electronics and computer programmer, whose curiosity led him to question ‘the voices and music coming from a box; a radio’. “In my quest to satisfy my curiosity, I collected many discarded devices, took them apart, and tried so many circuits, only to have them fail because the theory was lacking. After thousands of failed projects and with me barely thirteen and in lower secondary school, my first ever project actually worked,” he said.

NRF-rating
He is the author of the book Introduction to Control Systems Analysis using Point Symmetries: An application of Lie Symmetries, which is available in all major bookstores such as Amazon, in both print and e-book format. He is a C3 NRF-rated researcher whose work makes a pioneering contribution to the new and growing field of phononics, an independent field of the now established photonics.

“This field will someday lead to improved energy-storage devices and faster processors due to more efficient heat removal from nanodevices,” he concludes.

UFS Doctors make History in South Africa
2011-07-14

 

New aortic valve

Three members of our Faculty of Health Sciences made history by being the first to implant a special new aortic valve in South Africa. 
 
In a combined effort, the Departments of Cardiology, Pediatric Cardiology and Cardiothoracic Surgery did the first Medtronic CoreValve implant in South Africa on a patient in Universitas Academic Hospital. 
 
With the support of hospital management and the Medtronic company, Prof. Hennie Theron, Prof. Stephen Brown and Dr JP Theron of the Faculty of Health Sciences, with the assistance of Dr Jean-Claude Laborde, performed the operation early on Wednesday morning, 06 July 2011.
 
The advantage of this new valve is that it can be implanted percutaneously through a catheter from the groin. This eliminates the need for invasive surgery.
 
The valve is made from porcine pericardium (tissue derived from pigs) and is mounted on an expandable stent, which is threaded along an artery, until it reaches its desired position. Prof. Theron says the valve is especially useful in older patients who suffer from aortic valve disease and pose a high surgical risk. Furthermore, the use of this valve greatly reduces hospitalisation time, in comparison to traditional surgery.
 
“One patient already received an implant this morning and we hope to finish 2 more today,” Prof. Brown said, emphasizing the swiftness and efficiency of the new valve implanting process.
 
“It is a complex procedure, but this service can in future be offered to all patients in the public and private sectors of the Free State. It is heartwarming that the academic complex can take the lead in this modern, high-tech therapy.”
 
For more information on the procedure, please contact Prof. Theron at 051 4053428.
