Cutting-edge research can improve Africa: Dr Ocaya

06 March 2020 | Story Thabo Kessah | Photo Tsepo Moeketsi

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.

Mandela statues and the issue of public representation

2015-09-04

Prof Grant Parker, Associate Professor of Classics and Co-Director of the Centre for African Studies at Stanford University, USA, presented a public lecture on the Bloemfontein Campus on 27 August 2015, in which he explored the topic of ”Memorialising Mandela after Rhodes Must Fall”. What stories do the multitude of Mandela statues tell us about the man? Our society? Ourselves? These were some of the questions Prof Parker addressed during his lecture.

Paradoxes
Prof Parker discussed some of the paradoxes presented by the Mandela statues. The huge 9m high Mandela statue at the Union Buildings in Pretoria does not necessarily reflect his humility. Iconic statues strewn across the world do not reveal Madiba’s appeal. “Madiba’s charm,” Prof Parker said, “was all about his ability to relate to people of very different backgrounds. People who were his enemies would – to their surprise – find a humanity they were not expecting. It’s very hard to reconcile that with the colossal statues.”

Rhodes Must Fall
On the topic of the Rhodes Must Fall campaign, Prof Parker said that “the debates around it seem to express the frustration of deepening equality in general and lack of demographic change.” He also believes that, although the campaign centres on statues, there are much deeper issues at play that need to be addressed.

Artists should be part of the conversation
Prof Parker also advocated that artists’ voices should be incorporated into the creative processes of public art. “There is a much greater need for creative artists,” he concluded, “to be part of conversations, not only about what we as South Africans want to commemorate, but how we do that. I would very strongly suggest that this be done by non-figural representations.”
