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.

New yeast named after Bloemfontein

A second living organism was named after Bloemfontein, adding to the fact that the University of the Free State (UFS) has the largest yeast collection in the Southern Hemisphere.

In an article in the highly acclaimed scientific journal, International Journal of Systematic and Evolutionary Microbiology, three lecturers from the Department of Microbial, Biochemical and Food Biotechnology, at the UFS, Dr Carlien Pohl, Prof. Martie Smit and Prof. Jacobus Albertyn, describe four new yeast species.
 
One of these species, isolated from pine needles from Bloemfontein, has been named after this city and will be known as Rhodotorula bloemfonteinensis. ‘Rhodo’ refers to the redness of these types of yeast. This makes this yeast only the second living organism to be named after Bloemfontein. The other is a mite (Pilogalumna bloemfonteinensis), which was described in 1972.
 
In short, yeast is a micro-organism that is part of the fungi family. Prof. Albertyn, “The most common of these are the bakers’ yeast, of which the bloemfonteinensis forms part.”
 
Among these four species they discovered, the Rhodotorula pini was also discovered on the Bloemfontein Campus of the UFS during December 1995.
 
“The UFS now has the largest yeast collection in the Southern Hemisphere. All over the world, science is busy researching the field of bio-diversity. This promotes the bio-diversity at the UFS,” Prof. Albertyn says.
