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.

A team of cardiac doctors associated with the Robert WM Frater Cardiovascular Research Centre at the University of the Free State’s (UFS) Faculty of Health Sciences has commenced with a pioneering research project regarding idiopathic dilating cardiomyopathy.  

An Afrocentric research focus
Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS and Head of the Frater Centre, describes dilating cardiomyopathy as a heart muscle disease that is quite common, particularly among people of African descent. The disease weakens the heart muscle, which in turn leads to heart failure.

“To date there is no curable treatment for this condition and 50% of patients that have shown heart failure, died within a period of five years. The causes of this condition have been unknown in the majority of patients. But over the past few years major strides have been made where virus infections of the heart muscle or myocarditis have been identified as a possible underlying cause. Various genetic diseases are also linked to it,” says Prof Smit.

International collaborations ensure success
According to Prof Smit, the project is being run in conjunction with Prof Heinz-Peter Schultheiss of the Charité University and the Institute for Cardiac Diagnostics and Therapy in Berlin, Germany.

“We have been working on the project over the past 18 months and I have twice visited Prof Schultheiss in Germany. He is now visiting us in Bloemfontein. We have established a collaborative project focused on patients in central South Africa”.
Prof Schultheiss is a world leader regarding the diagnosis, pathology and treatment of dilating cardiomyopathy, says Prof Smit.

“He brings a lifetime of research experience to Bloemfontein and is internationally renowned as the father of myocardial or heart muscle biopsies.

“His pioneering work on the discipline has led to diagnostic accuracy that has induced purposeful and personalised treatment of dilating cardiomyopathy and has brought about dramatic changes in some subsets of patients’ life expectancy and their cure.”

Solving problems close to home
According to Prof Mokoali Makatoko, Head of the Department of Cardiology, there are more than 1500 new cases of heart failure identified annually at the Universitas Academic Hospital, of which approximately 30% are attributed to cardiomyopathy. “With the use of endomyocardial biopsies the team hopes to treat viruses unique to Southern Africa as well as other underlying causes of dilating cardiomyopathy.”

Prof Stephen Brown, Head of Paediatric Cardiology at the Universitas Academic Hospital, says children suffering from this disease never reach a mature age and those under his supervision will also be undergoing these tests. Various other departments at the UFS will also participate in this project. Profs Makatoko and Brown did the first four endomyocardial biopsies under the management of Prof Schultheiss during the past week. The results will be available in the coming weeks after which the project will be officially launched and patient recruitment will start in earnest.
