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.

South African born biophysicist and Nobel Prize-winner in Chemistry, Prof Michael Levitt, paid a visit to the University of the Free Sate (UFS) as part of the Academy of Science of South Africa’s (ASSAf) Distinguished Visiting Scholars’ Programme. 

Early this week the professor in structural biology at Stanford University in the US presented a captivating lecture on the Bloemfontein Campus on his lifetime’s work that earned him the Nobel Prize in 2013. His lecture launched the UFS Vice-Chancellor’s Prestige Lecture series, aimed at knowledge sharing within, and beyond our university boundaries. 

Prof Levitt was one of the first researchers to conduct molecular dynamics simulations of DNA and proteins and developed the first software for this purpose. He received the prize for Chemistry, together with Martin Karplus and Arieh Warshel, “for the development of multiscale models for complex chemical systems”.

Attending the lecture were members of UFS management, academic staff from a range of faculties and other universities as well as young researchers. “Multiscale modelling is very much based on something that makes common sense,” Prof Levitt explained. “And that is to makes things as simple as possible, but not simpler. Everything needs to have the right level of simplicity, that is not too simple, but not too complicated.”  

An incredible mind
Prof Levitt enrolled for applied mathematics at the University of Pretoria at the age of 15. He visited his uncle and aunt in London after his first-year exams, and decided to stay on because they had a television, he claims. A series on molecular biology broadcast on BBC, sparked an interest that would lead Prof Levitt via Israel, and Cambridge, to the Nobel Prize stage – all of which turned out to be vital building blocks for his research career. 

Technology to the rescue
The first small protein model that Prof Levitt built was the size of a room. But that exercise led to the birth of multiscale modelling of macromolecules. For the man on the street, that translates to computerised models used to simulate protein action, and reaction. With some adaptations, the effect of medication can be simulated on human protein in a virtual world. 

“I was lucky to stand on the shoulder of giants,” he says about his accomplishments, and urges the young to be good and kind. “Be passionate about what you do, be persistent, and be original,” he advised.
