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.

Double achievement for Prof. Paul Grobler

Early this year, two journal editions appearing almost simultaneously in Europe featured cover photographs based on papers by Prof. Paul Grobler of the Department of Genetics and his collaborators.

These papers stem from collaborations with Prof. Gunther Hartl at the University of Kiel (Germany) and Dr Frank Zachos from the Natural History Museum in Vienna (Austria). Both papers cover aspects of the genetics of southern African antelope species.
 
The first paper appeared in the Journal of Zoological Systematics and Evolutionary Research” (from the Wiley-Blackwell group). This was titled “Genetic structure of the common impala (Aepyceros melampus melampus) in South Africa: phylogeography and implications for conservation”.
 
In this paper, the team analysed impala from various localities in South Africa to determine the relationship between distribution and genetic structure. The results suggest a clear relationship between genetic characteristics and habitat features that regulate gene flow.
 
The second appeared in the journal Mammalian Biology (from the Elsevier group), with the title “Genetic analysis of southern African gemsbok (Oryx gazella), reveals high variability, distinct lineages and strong divergence from the East African Oryx beisa”.
 
Here, the researchers looked at various aspects of the genetics and classification of gemsbok. Among the notable findings is that gemsbok populations on the game farms studied are less inbred than previously predicted.
 
Proffs. Grobler and Hartl initiated these projects on gemsbok and impala, with sub-sections of the research later completed as M.Sc. projects by students from both South Africa and Germany.
 
Prof. Grobler has been involved with aspects of the population genetics of various mammal species since the early 1990s, and continued with this line of research after joining the UFS in 2006. Current projects in this field include work on wildebeest, vervet monkeys and white rhinoceroses.
