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.

Researchers focus on parrots, poultry and phage therapy

Veterinary biotechnology focuses on microbial and molecular biological approaches to veterinary illnesses. The group working on veterinary biotechnology research at the University of the Free State (UFS) consists of two academic staff members, Prof Rob Bragg and Dr Charlotte Boucher, two post-doctoral fellows, Drs Chris Theron and Arina Hitzeroth, five PhD and three honours students.

The group has three research focus areas.

Dr Boucher says, “Our main focus area is infectious coryza in poultry, caused by the bacterium Avibacterium paragalliarum. The aim is the control of the disease, mainly through improvement of vaccines, understanding the immune response and improved biosecurity. A key objective is improving methods for serotyping; studying of selected surface antigens and investigating the influence recently discovered bacteriophages might have on virulence. We have co-operative projects with research groups in China, India and Israel.

“The second focus area is an expression system co-developed with the National Institute for Agronomic Research (INRA), France. The flagship project is the expression of the coat protein gene of the beak and feather disease virus, a disease affecting parrots, currently threatening the endangered Cape parrot. This system has led to the development of serological tests, currently under patenting. The application of this system has been extended to human-related diseases, with two interdisciplinary projects underway, co-working with Profs Muriel Meiring and Felicity Burt. Prof Meiring is working on diseases causing bleeding disorders, such as blood-clotting impairment, while Prof Burt is working on viral infections causing haemorrhagic (bleeding) disorders.

“We are also researching disease control in a post-antibiotic era, investigating the potential of phage-therapy by targeting and destroying pathogenic islands within a host, with reduced side-effects on the host itself.

“We have smaller projects, including an interdisciplinary project with Zoology, looking at the protein profile of amphibian (frog) secretions with the focus on antimicrobial activity, as these secretions assist with protecting amphibian skin against infections.”
