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.

Renowned author and disability activist Helen Keller once said the problems that come with being deaf are deeper and more far-reaching than any other physical disability, as it means the loss of the human body’s most vital organ, sound.

Dr Magteld Smith, researcher at the Department of Otorhinolaryngology (Ear, Nose and Throat) at the University of the Free State, said hearing loss of any degree can have psychological and sociological implications which may impair the day-to-day functioning of an individual, as well as preventing the person from reaching full potential. That is why Smith is making it her mission to bring about change in the stigmatisation surrounding deafness.

Beating the odds
Smith was born with bilateral (both ears) severe hearing loss, which escalated to profound deafness. But she has never allowed it to hinder her quality of life. She matriculated from a school for the deaf in 1985. In 2008 she received a cochlear implant   a device that replaces the functioning of the damaged inner ear by providing a sense of sound to the deaf person   which she believes transformed her life. Today, she is the first deaf South African to possess two masters degrees and a PhD.

She is able to communicate using spoken language in combination with her cochlear implant, lip-reading and facial expressions. She is also the first and only deaf person in the world to have beaten the odds to become an expert researcher in various fields of deafness and hearing loss, working in an Otorhinolaryngology department.

Advocating for a greater quality of life
An advocate for persons with deafness, Smith conducted research together with other experts around the world which illustrated that cochlear implantation and deaf education were cost-effective in Sub-Saharan Africa. The cost-effectiveness of paediatric cochlear implantation has been well-established in developed countries; but is unknown in low resource settings.

However, with severe-to-profound hearing loss five times higher in low and middle-income countries, the research emphasises the need for the development of cost-effective management strategies in these settings.

This research is one of a kind in that it states the quality of life and academic achievements people born with deafness have when they use spoken language and sign language as a mode of communication is far greater than those who only use sign language without any lip-reading.

Deafness is not the end

What drives Smith is the knowledge that deaf culture is broad and wide. People with disabilities have their own talents and skills. All they need is the support to steer them in the right direction. She believes that with the technological advancements that have been made in the world, deaf people also have what it takes to be self-sufficient world-changers and make a lasting contribution to humanity.
