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.

“Zingisa, I saw the tears streaming down your face when you were being hooded,” said an emotional Dr Khotso Mokhele, Chancellor of the University of the Free State. “And you were not the only one with tears streaming down your face.”
 
Zingisa Ngwenya, a visually impaired BA Communication Science student, was one of those who graduated at the UFS 2016 Spring Graduation on 15 September 2016 at the Bloemfontein Campus. By her side were her guardians, Derek Watts, the presenter of the current affairs TV programme Carte Blanche, and his wife Belinda.

Dream becomes reality with support from community
Watts first met Ngwenya at the Audi Pioneer School Rally in Worcester, Western Cape, in which she was his co-driver. He admired her ability to read all her instructions in braille. “I was inspired by her because she had lost her sight late in her school career,” said Watts at the graduation ceremony. Ngwenya was academically strong and her aspirations to go to university led to the relationship.  

The UFS Centre for Universal Access and Disability Support, the Kirsty Watts Foundation, Gavin Fourie from Richmond, and Symington and De Kok law firm in Bloemfontein helped make Ngwenya’s dream a reality. “We managed the facility for her to do well, but it’s nothing compared to what she has done to get this degree,” Watts said.

Support from Watts family made things possible
Ngwenya will be studying towards a law degree at UFS, as well as working part-time at, Symington and De Kok. “She never bemoans what has happened to her in life. She just looks ahead to make the most of her life,” Watts said.

“Derek and Belinda’s support means everything to me. Without them it would not have been possible because it has really been a struggle, but they believed in me,” Ngwenya said.
