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.

Department celebrates 50th anniversary

On 13 March the Department Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS) celebrated its 50th anniversary in a splendid fashion with a lecture entitled, The origin of life: Exactly how did life begin? as part of the Darwin commemorative lecture series, followed by a reunion of current and former staff members and postgraduate students of the department with a barbeque on the following day.

The proceedings were concluded on 14 March with a gala dinner in die Centenary Complex at the UFS attended by 153 staff members, post-graduate students (current and former) and other guests. During the dinner the guests were treated to a presentation of historical photos of the founding and development of the department. Currently the department is one of the largest departments in the Faculty of Natural and Agricultural Sciences in respect of the number of staff members and students as well as research outputs. This is the result of entrepreneurial actions to increase student numbers and research activities, as well as the merging with the smaller Department of Biochemistry in 1988 and more recently with the Department of Food Science in 2002. The department comprises 20 academics, 24 support staff and 65 postgraduate students. It also boasts 12 lecturers with ratings from the National Research Foundation (NRF), which include three academics with a B-rating, an indication of international recognition for their research. The department has the largest number of lecturers with an NRF-rating at the UFS. 

“It was interesting to learn during the reunion of the variety of professions occupied by former students of the department, i.e. at other tertiary educational institutions, the CSSIR, SAPPI, Sasol and a multitude of other industries, as well as at research institutions in the USA and Australia,” said Prof. James du Preez, Head of the Department.
