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.

Researcher shares platform with Nobel Laureate at conference on nanomedicine

Profs. Lodewyk Kock and Robert Bragg from the Department of Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS) both presented lectures at the first International Conference on Infectious Diseases and Nanomedicine that was held in Kathmandu, Nepal, late last year.

At the conference, also attended by senior representatives from the International Union of Microbiological Societies (IUMS), Prof. Kock delivered one of the two opening lectures, titled: Introducing New Nanotechnologies to Infectious Diseases (the other opening lecture was presented by Nobel Laureate, Prof. Barry J. Marshal). Prof. Kock also participated in the farewell address.

In two excellent lectures, Prof. Bragg spoke on Bacteriophages as potential treatment option of antibiotic-resistant bacteria, and on Bacterial resistance to quaternary ammonium compounds.

For Prof. Kock this very first conference on infectious diseases and nanomedicine was followed by a very exciting yeast research excursion through the Mount Everest Highway which winds through the villages of the Sherpa tribe.

He describes his journey: “The Mount Everest Highway is a rough road stretching through hills and glacial moraines of unfamiliar altitudes and cold temperatures. Throughout the journey I had to take care of not contracting altitude sickness which causes severe headaches and dizziness.

“The only way of transport is on foot, on long-haired cattle called Yaks, donkeys and by helicopter. After flying by plane from Kathmandu (the capital of Nepal), I landed at Lukla, regarded as the most dangerous airport in the world due to its short elevated runway and mountainous surroundings. From Lukla, the land of the Sherpa, I walked (trekked) with my Sherpa guide and porter (carrier) along the Everest Highway surrounded by various Buddhist Mani scripture stands, other Buddhist representations and many spectacular snow-tipped mountains of more than 6 000 m above sea level. Of these, the majestic mountain called Ama Dablam (6 812 m), the grand 8 516 m high peak of Lhotse and to its left the renowned Mount Everest at 8 848 m in height, caught my attention.

“Dwarfed by these mountain peaks on the horizon, I passed various villages until I eventually reached the beautiful village called Namche Bazar, the heart of the Khumbu region and hometown of the Sherpa. This took three days of up to six hours walking per day, while I spent the nights at the villages of Phakding and Monjo. From there I walked along the Dudh Kosi River which stretches towards Mount Everest, until I reached the high altitude Everest viewpoint – the end of my journey, after which I trekked back to Lukla to return to Kathmandu and South Africa.

“This expedition is the first exploration to determine the presence of yeasts in the Everest region. Results from this excursion will be used in collaborative projects with local universities in Nepal that are interested in yeast research.”
