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.

An astrophysics pioneer at Kovsies

Prof Pieter Meintjes

Over the last decade Prof Pieter Meintjes’ strong background in astrophysics led to the development of a course of excellence at the University of the Free State.

Today we present an Astrophysics degree at our university, from first-year courses to PhDs.

Meintjes matriculated at the Sybrand van Niekerk High School in Sabie and completed a BSc in Physics and Mathematics at the North-West University in 1988. In 1990 and 1993 he respectively obtained his MSc and PhD in Physics from the same university.

Hereafter he spent a post-doctoral year at the Max Planck Institute for Space Science near München in Germany. In January 1997, Meintjes was appointed as a senior lecturer at our university’s Department of Physics. He was promoted to Professor in Physics in 2008.

Prof Meintjes is a member of the South African Institute for Physics (SAIP) and during 2002-2004 he was also co-chair of the astrophysics and space science group of SAIP. He serves on the executive committee of the National Astrophysics and Space Science Programme (NASSP) and is often a visiting lecturer at the University of Cape Town. He is a NRF-supported researcher and author and co-author of 70 publications in high-profile international journals and published conference issues.

During 2011-2013 he successfully delivered three PhD students along with one MSc student. His PhD students also delivered addresses at international conferences in Champery (Switzerland), Heidelberg (Germany), Paris (France), Barcelona (Spain) and Milan (Italy), Cape Town and the Kruger Game Reserve.

Over the last two years he has also been the author and co-author of six publications in Monthly Notices of the Royal Astronomical Society (MNRAS), as well as various publications in the Astrophysical Journal in support of the international planet search programme. A further 12 publications also came forth from Meintjes’ international conference contributions.

During the recent H.E.S.S. meeting in Namibia, Meintjes was appointed as the latest member of the highly-regarded international cooperation with H.E.S.S.

His membership of the H.E.S.S. group is due to his knowledge on gamma rays, which entails research on high-energy astrophysics.
