Dr Nashua Naicker
Dr Nashua Naicker, lecturer and Chairperson: Learning and Teaching Committee (SoHRS) in the Department of Optometry, UFS School of Health and Rehabilitation Sciences, graduated on Thursday (April 18) with the degree Doctor of Philosophy in Health Professions Education.

A strong need to improve the general standing of optometry as a profession and to create lifelong learning opportunities for locally trained optometrists beyond what currently exists, is what led Dr Nashua Naicker to pursue a PhD in this field.

Dr Naicker, lecturer, and Chairperson: Learning and Teaching Committee (SoHRS) in the Department of Optometry, UFS School of Health and Rehabilitation Sciences, says he feels an overwhelming sense of relief with a keen sense accomplishment by achieving what he set out to through persistence in the face of adversity.

He graduated on Thursday (18 April) at the Faculty of Health Sciences April graduation ceremony with the degree Doctor of Philosophy in Health Professions Education through the Division of Health Sciences Education. “I am pleased and hope to change the narrative on this new path as an accredited researcher from ‘how long are you going to take to finish?’ to ‘what have you learnt in this journey?’. We are far too focused on chasing a timeline rather than focusing on the contribution that one makes and the self-development in this journey of discovery,” says Dr Naicker. 

His supervisor was Prof Alvin J Munsamy from University of KwaZulu-Natal (UKZN) and co-supervisor Dr CB Written from the UFS.  

Need for educational expansion

His research was focused on establishing a framework for postgraduate programmes in specialty fields of optometry for South Africa. The investigation was carried out with practising optometrists as the primary stakeholders and with optometric academics as the custodians for education and training in the country.

“With an overwhelming need for educational expansion found in this investigation, a conceptual framework was proposed as the innovation to take the profession forward in South Africa. Improving patient care from being upskilled and receiving professional recognition for the additional competencies and proficiencies that would be gained, was the motivating factors identified by optometrists to consider further education and training,” says Dr Naicker.

According to him, being in the educational fraternity for almost two decades and as a former education committee member of the professional board of optometry, he was able to see where the shortcomings were in the profession which set him on this path to pursue this research. With most optometrists in clinical practice and no clinical postgraduate qualifications available except pure research-based qualifications in SA, Dr Naicker explains that this hindered optometrists’ professional trajectory and career path opportunities into various special interest areas. 

“By developing a framework for horizontal articulation pathways towards coursework postgraduate qualifications in various clinical specialty fields, this would be the contribution in addressing the educational gap that would guide higher education institutions in their programme development process. The beneficiaries of this expansion would not only be the health professionals but the patients who access optometric care from the optometrists who would have advanced skills and competencies to deliver comprehensive eye care services.”

Stayed motivated

Dr Naicker says the journey to his PhD was challenging from the outset as the country went into hard lockdown due the COVID-19 pandemic just five weeks after he registered for his PhD. Working on a PhD was not a priority at the time when your survival and that of your loved ones was uncertain as thousands of people fell victim to the coronavirus. Further to this, he continues, multiple changes to his supervisory team and the overhaul and revitalisation of the administration and management of the UFS Division of Health Sciences Education, also impacted his progress in his doctoral research at that time. He had felt despondent after a year of being registered when stability arrived with supervisory assistance that re-ignited his drive to pick up the slack and keep moving forward.

“The words ‘push through it’ were verbalised to me by a stranger I met in passing.  While chatting about research I found those three words to be so profound and with such depth that they resonated with my experience of facing adversity but remaining vigilant to preservere and not drop the baton in the race against time to conclude my research. Gaslighting yourself and questioning your potential to complete a PhD only compounds your procrastination which was all too apparent. The goal is to rise above the self-doubt, brush off the devil with the fork sitting on your shoulder and just ‘push through it’.”

Dr Naicker, who is currently supervising four master’s of optometry students in their research undertaking, as well as undergraduate research projects, says he is in the process of publishing the research manuscripts generated from his PhD and is also part of a task team with the professional Board of Optometry for setting up the board exams for foreign-qualified optometrists. He would also like to work on research involving educating the educators of visually impaired learners.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
