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.

Dr Henry Jordaan’s research to establish benchmarks for sustainable freshwater use in agri-food industries

Dr Henry Jordaan, Senior Lecturer in the Department of Agricultural Economics, is working on a multi-disciplinary research project for the Water Research Commission. The project assesses the water footprints of selected agri-food products that are derived from field and forage crops produced under irrigation in South Africa. These foods include animal products, such as meat and dairy, and crop products such as bread and maize meal.

“The water footprint of a food product is the total volume of freshwater that is used to produce the product, measured from the farm to the actual consumption of the food product. Thus, the water footprint is a good indicator of the impact that the consumption of a product has on our scarce freshwater resource. The agri-food sector is a major user of freshwater in South Africa with a relatively large water footprint,” says Dr Jordaan.

However, the agri-food sector also has an important role in economic development in South Africa. It generates income and employment opportunities along the value chains of the food products.

The challenge is to maximise the economic and social benefits from using freshwater in an environment where freshwater gets increasingly scarce.

Through his research, Dr Jordaan aims to establish benchmarks for sustainable freshwater use in selected agri-food industries – from an environmental, economic and social perspective. These benchmarks will inform water users on the acceptable volumes of freshwater to use to produce food products. It will also inform users of the economic and social benefits that they are being expected to generate through their actions so that their water use behaviour could be considered sustainable.
