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.

Prof Jeanet Conradie, professor in the Department of Chemistry at the University of the Free State (UFS), was the runner up in the senior category for Distinguished Women Researchers: Physical and Engineering Science in the Department of Science and Technology’s 2014 Women in Science Awards. With this award, female scientists and researchers are encouraged and rewarded, and also profiled as role models for younger women. 
 
Science and research, by which new concepts are discovered, is her great passion. Due to this keen interest in science, Prof Conradie studied a variety of subjects during her undergraduate years, providing her with a vast knowledge and the necessary background for her current main research interest, which is a combination of various scientific fields. Her PhD in Chemistry, as well as her strong background in Physics, Computer Science, Mathematics and Applied Maths, influenced her choice of research interest and expertise to gradually develop in the direction of computational chemistry, which is a beautiful combination of chemistry and physics. 
 
Today, Prof Conradie’s research expertise is in computational chemistry, using the super computer and appropriate software to simulate, understand and predict the behaviour of atoms and molecules in real life. The use of computational chemistry makes it possible to study chemical reactions and phenomena that are impossible or too dangerous to study experimentally. Her research team also performs experimental work in the laboratory to combine and compare with the computational analysis. Based on the results obtained, new materials with specific properties are developed. 
 
“We are very proud of Prof Conradie. This award is the result of 14 years of hard word, a lot of it after hours. We are fortunate to have someone like you as colleague who puts guidance to students and learners first in research, teaching and community service,” said Prof André Roodt, Head of the Department of Chemistry at the UFS. 
 
Prof Corli Witthuhn, Vice-Rector: Research said: “Prof Conradie serves as a role model for younger academic scholars in higher education through her motivation, productivity and drive. She also serves as an example of how female scientist can reach the top of their profession while juggling both professional and family responsibilities. This is well deserved recognition for her outstanding research achievements”
