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.

State of our campuses: UFS Bloemfontein and South Campuses closed on Tuesday 20 September 2016
2016-09-19

After much consideration, the senior leadership of the University of the Free State (UFS) decided to close the Bloemfontein and South Campuses on Tuesday 20 September 2016.

Bloemfontein Campus:
No academic and administrative services will be available and no lectures and/or tests will take place.

The decision comes after all academic activities were suspended this afternoon because of a growing unease on campus and disruption of some academic activities by groups of students resulting from this morning’s announcement on tuition fees by the Minister of Higher Education and Training, Dr Blade Nzimande.

The closing of the campus will afford an opportunity to the senior leadership to further engage with the Student Representative Council (SRC).

South Campus:
Because of problems with bus transport from the Bloemfontein Campus to the South Campus, no academic services will be available tomorrow. No lectures and/or tests will therefore take place. Administrative services will, however, continue, and staff on the South Campus have to report for work.

Qwaqwa Campus:

Academic and administrative services on the Qwaqwa Campus will continue as normal tomorrow.

Information about the situation on the campuses will be shared as and when it becomes available during the course of tomorrow.
