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.

Microbiologist Dr Adepemi Ogundeji has uncovered a new use for an old medicine that can potentially save lives and money. Under the guidance of her study leader, Dr Olihile Sebolai, Dr Ogundeji set out to fight a fungal disease caused by Cryptococcus neoformans. Drs Ogundeji and Sebolai are from the University of the Free State Department of Microbial, Biochemical and Food Biotechnology. 

Dr Ogundeji is passionate about education. “My aim will always be to transfer knowledge and skills in the microbiology field,” she said. “Dr Ogundeji’s study is celebrated in that it found a new purpose for existing medicines. An advantage of repositioning old medicines is by-passing clinical trials, which sometimes take 20 years, and the safety of such medicines is already known,” Dr Sebolai, explained.

Cryptococcus infections are difficult to control and often lead to brain inflammation. In layman’s terms: “Your brain is on fire”. People with HIV/Aids are especially vulnerable, surviving only about three months without treatment. Such patients may present with a Cryptococcus-emergent psychosis, and some with an out-of-control inflammatory condition when initiated on ARVs. 

Dr Ogundeji found that the clinically recommended dosage of aspirin (anti-inflammatory medicine), and quetiapine (anti-psychotic medicine) is sufficient to control the infection. Her exceptional work was readily published in some of the foremost journals in her field, namely, Antimicrobial Agents and Chemotherapy and Frontiers in Microbiology
