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.

Self-help building project helps to change lives

UFS PhD student Anita Venter did not know it in the beginning, but her doctoral research would eventually change her life and the lives of many others. 

The research was whether South Africa’s housing policies were socially and culturally responsive to grassroots reality in informal settlements. Venter agreed her research approach might have raised a few eye brows, but it was a journey she holds had more benefits than failures. 

Green living
For her case studies, Venter looked at ‘Start Living Green’ as a concept and further examined the implementation models of Earthship Biotecture Academy in New Mexico and Central America and the Long Way Home non-profit organisation in Guatemala. 

These groups train people with no specialised construction skills in applying and managing environmentally sound self-help building projects. Furthermore, their primary objectives were not building-related, but people-centred, with an advocacy role to create social, environmental and educational change through utilising the building technologies. 

It resulted in Venter signing up for a course in Guatemala to get the skills to implement her case studies here at home in Bloemfontein. 

An experimental mud, straw and waste material structure in her back yard grew into similar houses built in informal settlements, through the transfer of knowledge of indigenous building methods.  

Are rickety corrugated iron shacks only alternative?

Her case studies, one in Freedom Square in the Mangaung Metro Municipality, highlighted, among others, baffling tenure insecurities and “tangible conflicts” entrenched between Westernised and African perspectives on home ownership.

Venter says her thesis, in essence, did not oppose existing housing strategies but did challenge the applicability of an economically inclined model as the most appropriate housing option for millions of households living in informal settlements. 

The main findings of the case studies were that self-help building technologies and skills transfer could make a significant contribution to addressing housing shortages in the country; in particular in geographical locations such as the Free State province and other rural areas.

Venter’s own words after her academic endeavour are insightful: “These grassroots individuals’ courage to engage with me in unknown territories, gave me hope in humanity and inherent strength to keep on pursuing our vision of transforming informal settlements into evolving indigenous neighbourhoods of choice instead of only being living spaces of last resort.”

Positive results 
The study has had many positive results. The City of Cape Town is now looking at new innovative building technologies as a result. Most importantly Venter's study will open further discussions that necessarily challenge the status quo views in housing development.
