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.

Otorhinolaryngology research hopes to decrease morbidity

Otorhinolaryngology at the UFS

Prof Riaz Seedat, Head of the Department of Otorhinolaryngology at the UFS is a world-renowned ear, nose and throat specialist and researcher. He is also a National Research Foundation C3 rated scientist.

He is conducting his research in ear, nose and throat (ENT) pathology in a developing world setting, particularly focusing on recurrent respiratory papillomatosis and other ENT conditions. “This condition is caused by human papillomavirus (HPV), infective conditions as well as allergic rhinitis,” said Prof Seedat.

Current research is aimed at further describing the epidemiology of recurrent respiratory papillomatosis, identification of the HPV variants responsible for causing the condition and markers of disease aggressiveness.

The research has led to various international partnerships such as the multicentre collaborative studies, “Genetic Susceptibility to Papilloma-induced Voice Disturbance” at the Centre for Genomic Sciences at the Allegheny-Singer Research Institute in Pittsburgh, United States, and the HPV6/11 Global Diversity Consortium at the University of Ljubljana in Slovenia.

Although most head and neck squamous cell carcinomas are caused by excessive tobacco and alcohol use, there is an increasing body of evidence to show that HPV causes a subset of head and neck squamous cell carcinomas. However, there are few studies on the role of HPV in head and neck neoplasms in developing countries.

“Through the research we have shown that recurrent respiratory papillomatosis, caused by HPV, is not as rare in South Africa as it is in developed countries and that patients usually present respiratory papillomatosis at an advanced stage when the condition is life-threatening,” said Prof Seedat.

“It is hoped that this research will help us to address the morbidity caused by ENT conditions common in developing countries,” said Prof Seedat.
