PhD Awardee Tackles Cosmology
Dr Sphakamiso Mlaba graduated with his PhD in Applied Maths with his parents support.Dr Sphakamiso Mlaba graduated with a PhD in Applied Mathematics at the University of KwaZulu-Natal.
Mlaba, who hails from rural Kranskop, chose to pursue a Bachelor of Science degree in Applied Mathematics and Statistics during his undergraduate studies because of his interest in Mathematics, Science and Physics in high school. Thereafter, he completed his Honours in Applied Mathematics for his research paper on Financial Mathematics (interest rate modelling). During his honours he received a merit certificate in Cosmology for his interest in Physics.
‘I then decided to do research in Cosmology (the study of the universe) for my masters which was supervised by Dr Sudan Hansraj with the help of Prof Sunil Maharaj from the Department of Mathematics,’ said Mlaba.
Mlaba’s research investigated the Einstein-Maxwell system of equations that govern the gravitational behaviour of charged spheres. He said his research has a big impact on society. ‘Cosmology has a big impact on society without society even realising it. Humans have been trying to make sense of the universe and have been unknowingly proposing cosmological theories. The notion of a deity often plays a central role in these cosmological theories. With most religions, God is the sole creator and sustainer of the universe. But the last hundred years have seen a different sort of cosmology, a scientific cosmology. The notable characteristics of scientific cosmology are that it uses mathematical physics to make testable and precise predictions,’ said Mlaba.
Growing up in a disadvantaged community made Mlaba’s studies towards his masters and PhD very challenging.
‘During my undergraduate level I had to tutor part-time, just to help myself and my family financially. I worked hard to ensure that I could take care of my family and continue with my studies. I started working at South African Home Loans as a quantitative analyst graduate while doing my masters. Working and studying full-time was not easy. I remember my friends telling me I had no life but for what it was worth, I have no regrets,’ said Mlaba.
Despite the challenges, Mlaba did not give up but instead persevered and overcame the challenges. ‘The fighting spirit in me didn’t allow me to quit and I soldiered on in order to achieve my goals. I know that nothing is impossible and that I’m a much stronger person because of my journey,’ he said.
Mlaba is currently working at First National Bank (FNB) as a quantitative analyst. He plans to continue working in the corporate environment in order to explore his analytical thinking and skills in the banking industry. He hopes to pursue his postdoctoral studies in Cosmology and later, return to academics to lecture and continue with global research in cosmological studies.
Mlaba acknowledged and thanked his family and friends for their great support and patience throughout his journey.

Dr Tonderai Mombeshora graduated with his PhD in Chemistry with his family by his side.Dr Tonderai Mombeshora graduated with a PhD in Chemistry and is ready to make an impact in the world for the betterment of society.
Mombeshora tackles nanotechnology where his research work investigated usage of nanostructured materials, namely, multiwalled carbon nanotubes (MWCNTs) and reduced graphene oxide (RGO) in electrochemical double layer capacitors (EDLCs) as energy storage devices.
‘The main goal was to explore physicochemical properties and pursue feasible strategies of enhancing the energy storage functionality by use of carbon-based nanomaterials,’ says Mombeshora.
He explains that his research plays a huge role in society: ‘my MSc and PhD work impacts the local societies towards development of new, cost-effective, reliable, long-lasting and environmentally friendly energy storage systems (ESS) with quick energy delivery as a support to ever-rising energy needs. The ultimate goal is the development of intelligent ESS that maximise and provides durable storage of electrical power generated. This is a suitable approach towards reducing gas emissions, lowering electricity bills, meet power needs at any time and for lowering excess power fluctuations in our local societies.’
Mombeshora said graduating means ‘finally being a certified Chemical Scientist and tried and tested theorist.’ It was a gratifying moment for Mombeshora who faced a number of setbacks during his studies.
From a water crisis that could have potentially delayed his research, to frequent power cuts during 2015 and 2016, disheartening comments from reviewers and the “Fees Must Fall” student protest in 2016. Mombeshora said the major problems were the availability of instruments and the breakdowns, which took some time to be repaired.
Mombeshora overcame the challenges and is proud that all the chapters of his thesis were published in reputable peer-reviewed journals. ‘I had to go beyond my research team, School and at times outside the University itself just to get things done in good time. I kept pushing harder and soldiered onwards,’ he said.
Mombeshora is looking forward to the future and plans to impart his scientific knowledge and lead the local communities towards better lifestyles and standards of living.
‘I aspire to move beyond laboratory “test tube research” to industrial-related research and commercial products. I want to be amongst the leading research personnel with hands on experiences and expertise. I want to become a consistent researcher in terms of productivity and have more scientific article contributions in high impact journals over the next couple of years,’ said Mombeshora.
His advice to undergraduate students: ‘Keep your eyes on the prize and don’t allow anything to distract you, and above all, keep God at the centre of everything. Remember to work hard and remain dedicated. With hard work you will surely achieve your dreams.’
Professor Vincent Nyamori, Mombeshora’s main supervisor, had this to say about Mombeshora: ‘Dr Mombeshora was a diligent and self-driven research student. Very proud of his excellent PhD completion. It was a very impressive result, as a matter of facts, one of the External Examiner comment was, ‘I have to state that throughout my research career I have never had the opportunity to review a thesis of this excellent quality. It was a great privilege to perform this task!’
Mombeshora attributed his success to God and thanked his wife and family ‘who have always been pillars of moral and emotional support throughout this journey’. He also acknowledged his mentor, Professor Reuben Simoyi, his supervisors, Professor Vincent Nyamori and Professor Patrick Ndungu and Dr Leigh Jarvis for their advice and support.
When asked what inspiring greatness meant to him, Mombeshora said: ‘Being a positive motivation to other people through the way one handles and does things in life and having a positive effect in the lives of other people around. Also, to me, it means admiring and striving for excellence (greatness).’

Mr Mthokozisi Mdlalose graduated with his Masters in Physics with the support of his family.Mr Mthokozisi Mdlalose graduated with a Masters in Physics at the University of KwaZulu-Natal. His passion for astronomy had previously earned him summa cum laude when he graduated with a Bachelor of Science in Applied Mathematics and Physics, majoring in Astrophysics at the University.
Mdlalose fondly recalled how as a young boy he used an empty packet of chips as a filter to view a solar eclipse.
After completing matric at Sukuma Comprehensive School in Pietermaritzburg, Mdlalose pursued a Bachelor of Science (BSc) at the University of KwaZulu-Natal (UKZN).
In 2014, Mdlalose embarked on his BSc Honours degree in Physics. His exceptional results saw him scooping the 2016 UKZN Talent Equity and Excellence Scholarship award. Mdlalose effortlessly graduated cum laude with his BSc Honours degree in Physics.
‘Astronomy has been used for thousands of years to understand the connection that exist between earth, the solar system and the whole universe. The principle derived from astronomical observation has been used to develop a day-to-day life of human beings. It was an inherited curiosity about the interconnectedness of the universe and the inevitable task to address poverty, inequality and injustices that propelled me to study Astronomy,’ said Mdlalose.
Thereafter Mdlalose set his sights on doing his master’s degree with Professor Jonathan Sievers. His research focused on the Quasi-Redundant Calibration. It was to look at how high sensitivity telescope and high precision calibration instruments such as the Precision Array to Probe the Epoch of Re-ionization (PAPER), Hydrogen Epoch of Reionization Array (HERA) and SKA-low (located at Karoo, Northern Cape) is able measure the 21cm signal radiated by neutral hydrogen from a distance past around 100-500 millions after the Big Bang “the creation of the universe”.
Cosmologists will use the 21 cm signal to study the physics behind the formation of the first stars and galaxies, and further answer the question about the nature of mysterious dark matter and dark energy.
Mdlalose’s master’s research investigated the impact of instrumental imperfections that can potentially make the 21 cm signal measurement impossible. In addition, he employed a new technique calibration to mitigate those instrumental imperfections.
Currently Mdlalose is doing a PhD in Physics under supervision of Professor Yinzhe Ma and Professor Jonathan Sievers, exploring similar research but focusing on analysing real data from HERA-19 (located in SKA site, Karoo). His future goal is to complete his PhD by 2020 and then pursue a two-year postdoctoral degree. Ultimately, Mdlalose wants to lecture in the School of Chemistry and Physics.
Mdlalose was grateful to his supervisor, Professor Jonathan Sievers for his guidance and giving him opportunities to attend the Summer School programmes at the University of Pennsylvania and University of Toronto.
In his spare time, Mdlalose has a keen interest in Social Entrepreneurship. He is a founding member of the Afrikan Emancipation Student Movement (Afri-ESM) which is based at the Westville campus, UKZN. One of his own ventures includes being part of a fast growing startup called Black Diamond Suit.

Ms Terricia Govender graduated with her Honours in Physics with her family’s support. Her fiancé graduated as well.A school assignment on future career choices triggered Ms Terricia Govender’s interest to enroll at the University of KwaZulu-Natal towards a Bachelor of Science (BSc).
Govender, formerly from King Williams Town, in the Eastern Cape, matriculated at Kingsway High School, in KwaZulu-Natal. During her Grade 11 year, she conducted an assignment on possible future career choices called “work week”. With the help of her mother, Linda, they researched suitable science career paths online and came across the Astrophysics and Cosmology Research Unit (ACRU) at the University of KwaZulu-Natal (UKZN).
Under the guidance of Professor Kavilan Moodley, Govender gained more insight into astrophysics, completed a report on exoplanets and became the first ACRU representative at Kingsway High to initiate the school’s first astronomy club. This experience led to her enrolling at the university.
‘I was passionate about understanding where everything came from and how it exists and works from a scientific view. I was able to attend various public talks associated with ACRU which expanded my knowledge of the vast amount of research that was being done locally and internationally,’ said Govender.
In 2016, she graduated with her undergraduate BSc with a triple major in Mathematics, Physics and Astronomy, the first to have done so through UKZN, as the Astronomy major was newly introduced.
Govender’s results allowed her to undertake her honours degree with the National Astrophysics and Space Science Program (NASSP). During her honours year she had the opportunity to travel to Cape Town and Sutherland, thanks to the programme and funding of NASSP. This trip involved many aspects such as talks and lectures at the University of Cape Town (UCT) and star gazing, as well as a tour of the Southern African Large Telescope (SALT). Govender said, ‘It was an amazing experience to visit SALT and star gaze using telescopes that allowed us to see not only the moon very clearly but also objects deep in space.’
Her honours project on Inhomogeneous Spherical Dust Collapse in General Relativity, for which she obtained a certificate of merit, was supervised by Dr Rituparno Goswami.
Govender balances her academic life with her love for yoga, Zumba, cooking and hiking. She thrives on a good challenge and described her honours degree, which she completed last year as, ‘challenging, but with dedication, determination and hard work, success will always follow.’
Goswami, who has interacted with Govender since her third year, said Govender has a deep interest in relativistic astrophysics, and therefore chose to do her honours project with him on gravitational collapse of dustlike matter. ‘Terricia is one of those students who tries to understand deeply what she is working on, and would not let go until she is satisfied with her understanding. She dug out various reference materials by herself, went through them and asked me questions, proving how serious she was with her project.’
Govender is currently doing her Master of Science (MSc). Her topic is The Gravitational Collapse of Spherically Symmetric Stars, in relation to general relativity. She plans to do a PhD and contribute to the scientific community.
Govender is grateful for the support she received from her family, ACRU and NASSP in pursing her studies.
Her mother said she was proud and privileged to pay honour to her daughter. ‘Terricia is a very independent student who is highly dedicated in her studies and works with minimal supervision or need of assistance. She dedicates long hours to her studies. She leads a very balanced life. She has embraced religion and health without being fanatical. She is also socially responsible, demonstrated by her participation in a fundraising drive for Autism Awareness. I am undoubtedly a proud mother of an amazing daughter!’

Honorary graduate Professor Tebello Nyokong with Vice-Chancellor and Principal, Dr Albert van Jaarsveld.University of KwaZulu-Natal honorary graduate Professor Tebello Nyokong has made a name for herself as a female scientist in South Africa, breaking ground in scientific developments related to photodynamic therapy for application in cancer treatment, and in building capacity in chemistry.
Nyokong, who was presented with a Doctor of Science at the University’s Graduation ceremony, said she was honoured to receive the distinction and join the body of proud alumni at one of South Africa’s top universities.
‘I think it is still very rare for scientists to be recognised in this manner. I am used to seeing poets and musicians being honoured in this way, so I am delighted,’ she said.
Nyokong holds a Department of Science and Technology (DST) and National Research Foundation (NRF) professorship in Medicinal Chemistry and Nanotechnology at Rhodes University, as well as a rare A-rating from the NRF.
Nyokong spent time in Lesotho as a child where time at school was interspersed with shepherding duties. Inspired by nature and initially inclined toward the arts, during her high school years she decided to pursue the sciences, developing a passion for chemistry.
She continued her tertiary studies in chemistry at the National University of Lesotho (NUL), and attended McMaster University and the University of Western Ontario on a Canadian International Development Agency Scholarship, where she received her Master's and PhD degrees respectively in the late 1980s. She then went on to hold a Fulbright Fellowship for post-doctoral study in the United States.
Nyokong returned to Africa to teach at NUL, before joining Rhodes University in 1992 where she quickly ascended to the position of full professor and established a renowned research laboratory, now featuring advanced equipment loaned by the National Laser Centre, and equipment funded by the NRF and Mintek. In this laboratory, she pioneered photodynamic therapy methodology, a chemotherapy alternative with fewer side effects involving use of the harmless dye giving blue denim its colour. The dye initiates cancer cell death after activation with a red laser beam. She has also contributed to the fabrication of molecular sensors for environmental, biological and medical applications.
Nyokong’s list of accolades is long and illustrious, and includes an Adjunct Professorship in Norway, a registered patent, more than eight books and book chapters, 670 refereed journal publications and recognition by the NRF as one of the top three publishing scientists in South Africa. She has served as editor and on editorial boards of renowned international journals and was awarded the Third World Academy of Science (TWAS) medal in 2013 for her outstanding contribution to science and technology. She holds numerous honorary doctorates in science, is a Fellow of the Royal Society of Chemistry and the TWAS, a member of the Academy of Science of South Africa, and was named by the National Centre for Research on Human Evolution, Spain, as one of 12 names likely to change the world.
She was one of the first South African scientists to win the L’Oréal-UNESCO award for women in science in 2009 in the Physical Sciences category. She calls this one of her most life-changing awards, as it increased her international visibility and put African science on the world map. As a result, she influenced science and technology policy in Africa, addressing ministers of science and technology and young researchers across the continent.
She was also appointed by former United Nations (UN) Secretary-General, Ban Ki-moon, to the UN Secretary-General’s high-level panel on technology bank for least developed countries, and was invited by Irina Bokova, Director-General of UNESCO, to be a member of the UNESCO High-level panel on Science, Technology and Innovation for Sustainable Development.
Another milestone award was the Kwame Nkrumah Scientific Award from the African Union, which afforded her the opportunity to address African heads of states.

Dr Byron Brassel obtained his PhD in Applied Maths, pictured with his parents and brother by his side.Problem solver with a curiosity in Astronomy, Dr Byron Brassel, obtained his PhD at the University of KwaZulu-Natal.
Hailing from the beautiful Seychelles islands, Brassel's PhD research probed the dynamics of massive radiating stars in four and higher dimensions. It included studying the structure or geometry of a radiating star as well as its behaviour and finally the dynamics of its eventual collapse under gravity.
Brassel’s research obtained fundamental results in Einstein-Gauss-Gravity, which is one of underlying theories in modern physics. He has published in leading scientific journals such as Physical Review D.
After matriculating at Pinetown Boys’ High School, in Durban, Brassel undertook an undergraduate degree, a Bachelor of Science majoring in Mathematics, Applied Mathematics and Statistics.
After his undergraduate degree, Brassel completed his honours, summa cum laude and master’s with a cum laude in the School of Mathematics, Statistics and Computer Science (MSCS). Brassel was certain that if he continued his postgraduate studies at MSCS, he would have the opportunity to work with some of the top rated researchers.
After completing his master’s Brassel realised that he could combine the worlds of astrophysics and mathematics. This led him down the “fun ride” of his PhD research into general relativity and higher dimensional modified gravity.
‘Society has always had a curiosity and fear of the unknown. With astronomy it is certainly curiosity, but also wonderment. We look up at the stars with a large degree of awe, and when we were children, there was the notion of dreams attached to that too. One of the most beautiful ways to introduce and humanise science is to show people the cosmos,’ said Brassel.
Brassel described his doctoral studies ‘as an absolute joy that gave me opportunities to present at several international conferences and network with researchers from diverse areas.’
MSCS Research Chair, Professor Sunil Maharaj, said: ‘Byron Brassel always wanted to study mathematics and physics, and completed his BSc, BSc (Hons) and MSc with an outstanding academic record. During his doctoral studies he presented papers at international conferences in the US, Russia and India. He is a dedicated and remarkable student and a pleasure to supervise.’
Brassel received the Department of Science and Technology (DST)-National Research Foundation (NRF) Scarce Skills Postdoctoral Fellowship to conduct research at UKZN over the next two years under the supervision of Maharaj. He hopes to continue doing research coupled with teaching students and ultimately undertaking a higher doctorate.
He still finds time to write poetry and play his 7-string guitar.

He studied the decoherence of surface plasmon polaritons in metallic waveguides in the quantum regime and the first-order and second-order correlation functions for surface plasmon polaritons in metallic nanowire emitted by fluorescence from cold atoms.
Dlamini said ‘the results of the work on nanowires and nanofibers would be useful in studying and manufacturing new nanoscale photonic devices that were high quality and high performance and suitable for future hybrid quantum devices based on atom and photon behaviour. The devices that are constructed using the sub-wavelength diameter nanowires may have important applications for developing quantum networks’.
Dlamini holds a Bachelor of Science (BSc) in Applied Physics, BSc Honors and Masters in Physics. He said the more he continued doing physics, the more interesting he found it to be.
Dlamini said there were times when he felt demotivated when the experiments did not work out. ‘Aligning yourself with people who are positive and supportive, keep pushing you and never giving up no matter how difficult the problem is, is what made me overcome the struggles,’ said Dlamini.
He advised undergraduate students ‘to remain focused and study wisely.’
Dlamini attributed his successes to the guidance of his supervisors, Professor Francesco Petruccione, Professor Mark Tame and Professor Sile Nic Chormaic. He thanks his wife and family for their loving support.
‘I supervised Sanele during his MSc and PhD studies. It was a pleasure to see him grow as a human being and as a scientist. He never lost focus of completing an excellent PhD. I am sure he will achieve further ambitious goals, without losing his gentle, generous and humble character,’ said Petruccione.
When asked what inspiring greatness meant to him, Dlamini said: ‘Becoming the best I can be and for people to look at what I have achieved, and be motivated to further their studies.’

Mr Rajeev Maharaj walks across the graduation stage to receive his Masters in Mathematics.Mr Rajeev Maharaj graduated cum laude with Master’s in Mathematics at the University of KwaZulu-Natal.
In his research Maharaj tackled the pronormality in finite groups. ‘The dissertation was largely motivated by his aim to produce a survey on the theory and associated concepts of pronormality in finite groups. This was done by progressively addressing the properties, characterisations and generalisations of pronormality in finite groups,’ said Maharaj.
Maharaj initially pursued a degree in Chemical Engineering at UKZN but due to certain health issues and other factors, he chose to opt out of the degree.
‘It was a great learning experience. I was intrigued by the variety of Mathematics that was taught to us,’ Maharaj.
This led to him pursuing a BSc M Stream degree at UKZN. ‘I always had a passion for Mathematics. It was something that always intrigued me. The general consensus in the world is that Mathematics is very difficult but at the same time it is very important in various facets of our lives,’ said Maharaj.
Maharaj has encountered some struggles in his journey to graduation, but with the assistance from his lecturers and his determination to pull through and adhere to deadlines, he was able to overcome these obstacles.
‘It was a struggle to find a topic for my dissertation. I also struggled with reviewing high volume content that was fairly unknown to me. I had to grasp a lot of concepts in a short amount time and adhere to deadlines that were set,’ said Maharaj.
‘My advice to students is to always have good time-management. They should devote more time to the courses in which they are having difficulties. Reading other textbooks and finding additional material on the internet may be helpful too.’
Maharaj’s supervisor, Bernardo Rodrigues, said: ‘Among many of Rajeev’s characteristics, those that have impressed me are his humbleness and respectful nature. Rajeev has grown into a mature and quite independent person. These are important traits to have if one’s goals are the academic path and research enquiry’.
Maharaj is currently pursuing his PhD in Mathematics. Once completed, he hopes to continue academia but also collaborate on projects with esteemed international researchers in the field.

‘The essence of my research project is to introduce QKD to undergraduate students, enabling them to learn and acquire in-depth knowledge of the fundamental laws of physics, in particular Quantum Mechanics,’ she said.
QKD refers to the use of physical processes to transfer information using a quantum carrier in the form of single photons through a quantum channel.
Phehlukwayo is excited about its potential to offer the country a better and more robust way of securing information.
Her work has taken her to two conferences to present her results, and afforded her the opportunity to attend a winter school in quantum communication in Switzerland in 2016.
The Mshweshwe High School alumnus pursued her undergraduate and honours degrees at the University of Zululand, choosing to study Physics because of her love of nature and her quest to better understand how nature behaves.
‘Physics describes how matter and atoms interact with the environment,’ said Phehlukwayo. ‘As a subject it is naturally challenging, however, it is fun when determination is one’s ultimate goal.’
After receiving her honours, Phehlukwayo chose to further her studies at the University of KwaZulu-Natal (UKZN), thanks to it being among the top four rated universities on the continent and home to the only Centre for Quantum Technology in South Africa.
Phehlukwayo is now pursuing a PhD in Quantum Communication within the Quantum Research Group at UKZN, where her exposure to research has trained her for the academic career she is aiming for.
Phehlukwayo has worked hard to achieve her academic goals while also juggling the responsibilities and demands of motherhood.
‘I would like to express my sincere gratitude to my supervisor, Prof Francesco Petruccione, and co-supervisor Dr Yaseera Ismail for the role they have played during my studies, training me to be the best student I am today,’ said Phehlukwayo.

Ms Yurisha Goorun graduated with her Honours in Computer Science summa cum laude.Graduating summa cum laude with a Bachelor of Science Honours in Computer Science gave Ms Yurisha Goorun a sense of relief, accomplishment and the feeling that she made it despite the odds.
‘The field of computer science offers endless opportunities. It enables you to create and develop new technologies. I have a passion for software technologies and computer science opens the door for me to do what I enjoy on a daily basis,’ said Goorun. She hopes her work will lead her to cutting-edge research in artificial intelligence.
Goorun admits that her biggest struggle at university was making the adjustment from high school. ‘High school does not prepare you for university. In high school you are given a defined way to solve problems, but at university you have to teach yourself to apply yourself to solve problems,’ she explains.
She has practical advice for her fellow students. ‘Ambition and passion is key, set a goal and stop at nothing to achieve it. There will be days when you just want to quit and you will make many sacrifices along the way, but remember why you’re at university and that you have goals to achieve. If you don’t have any passion for what you do, no amount of motivation will get you through this journey,’ she said.
Goorun dissects UKZN’s tagline, inspiring greatness. ‘Inspiring greatness means to show up and be there for the people in your life. Greatness is in the little things that you do to help others which makes you a better human being at the end of the day,’ she said.
Goorun acknowledges that being successful takes a village. ‘My success is attributed to every single person who has been there for me during this journey, constantly reminding me that I can get through this’.
One of her lecturers, Mr Anban Pillay, said they were very proud of Goorun’s outstanding results and expect her to achieve great things in the future. ‘Her effervescence and enthusiasm is infectious. It is our hope that she inspires more young women to excel in STEM,’ he said.

Ms Josiane Ayingeneye graduated with her Masters in Chemistry.Rwandan national, Ms Josiane Ayingeneye, hitch-hiked to South Africa to undertake her postgraduate studies at the University of KwaZulu-Natal in the School of Chemistry and Physics.
After finishing school with a distinction at Nyamasheke Girls’ High School in the Western Province of Rwanda, Ayingeneye pursued her undergraduate degree at the National University of Rwanda with an interest in biochemistry.
In 2012, Ayingeneye completed her undergraduate degree with Honours in Bio-organic Chemistry. After reading about the excellent research facilities at the University KwaZulu-Natal (UKZN), Ayingeneye knew this was the institution she wanted to undertake her postgraduate studies at.
With insufficient funds for an air ticket, Ayingeneye hiked in 2015 from Rwanda to South Africa with the help of good Samaritans, to undertake her postgraduate studies at UKZN in the School of Chemistry and Physics. In addition to financial challenges, Ayingeneye could not communicate in English as French was the medium of communication in her home country. Undeterred by these obstacles, she enrolled for her Masters in Science.
Ayingeneye researched green chemistry, with a focus on alternative greener solvents which will substitute common solvents, which release harmful and volatile organic molecules in the air and environment. Her research involved the synthesis and application of “ionic liquids” as a medium for chemical reactions. Ionic liquids are salts which are liquids below 100 oC. Their low volatility, inflammability, high thermal stability, ability to dissolve a wide range of organic/inorganic compounds and recyclability make them more effective and preferable than common volatile organic solvents. The objective of the research was to synthesise useful alcohols by using a green solvent (a typical ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate, [BMIM]BF4).
Ayingeneye’s results showed that the design of new processes, which replace volatile organic solvents, was a promising and positive response to environmental pollution and human health detriments.
‘I am so proud and happy to be the first female in my family to complete a master’s degree,’ said Ayingeneye. She thanked her husband, Antoine Ayinkamiye, who despite having a low income, still managed to support her throughout her studies. During her study Ayingeneye was also blessed with a baby girl, named Dorcas Ishimwe Ayinkamiye.
‘All this success could not be achieved without the hard work, patience and scientific guidance of my supervisor, Professor Vincent Nyamori. His invaluable support will stay with me in my heart forever,’ said Ayingeneye.
Nyamori, of the School of Chemistry and Physics said: ‘Despite all the obstacles she encountered, Ayingeneye showed tenacity of spirit and made the 2018 list of graduates. I am very proud of her achievements. I can sum her journey as “Excellence is to do a noble common thing in an uncommon way”.’

Ms Zahra Essack graduated with a Masters in Astrophysics, cum laude.Developing an algorithm to search for planets outside the solar system earned Ms Zahra Essack a Master of Science (MSc) cum laude in Applied Mathematics (Astrophysics) at the University of KwaZulu-Natal. This brings the number of degrees Essack has received from the university to three, preceded by a Bachelor of Science and Bachelor of Science Honours – both awarded summa cum laude – in 2016 and 2017 respectively.
Essack developed an algorithm to detect transiting exoplanets in light curve data from NASA’s Kepler Space Telescope. A transit occurs when a planet passes across the face of its host star and blocks out some of the star’s light. The blocking of star light creates dips in the light curve of the star (a light curve is a plot of brightness vs. time). If these dips occur periodically, it can be indicative of the presence of an exoplanet orbiting the star. The shape of the dips provides information about the size, period and orbital distance of the exoplanet.
Essack’s research was funded by an Innovation Masters Scholarship from the Department of Science and Technology – National Research Foundation (DST-NRF) and the Vincent Maphai Scholarship, awarded to the top-ranked masters student in the entire university.
In addition to receiving the Dean’s Commendation for eight consecutive semesters, Essack was the top student in the College of Agriculture, Engineering and Science throughout her bachelor and honours degrees. She was the recipient of nine scholarships from UKZN, most of which she accepted without purse, allowing them to be reallocated to other deserving students.
Among her achievements, Essack received the Brenda M Gourley Scholarship in 2015 when she was ranked second undergraduate student in the entire University, the Zac Yacoob Scholarship in 2016 for being the best student proceeding to an honours degree and the Maryam Babangida Scholarship in the same year for being the best female student in the entire university progressing from undergraduate to honours study. She also received the National Research Foundation Square Kilometre Array (NRF-SKA) Scholarship from 2014–2016.
Essack is presently pursuing her doctorate at the Massachusetts Institute of Technology (MIT) in the United States, supervised by Professor Sara Seager, a world leader in exoplanet research.
After attaining her PhD, Essack hopes to return to South Africa to start a Centre for Excellence in exoplanets. Centres of Excellence are an initiative of the DST-NRF which focuses on research excellence, capacity development as well as inter-disciplinary and inter-institutional collaboration.
‘South Africa has become a radio astronomy hub with the SKA project. In setting up a Center of Excellence on exoplanets upon my return to South Africa, the future generation of radio astronomers will have another field to pursue, a field not yet fully tapped into in South Africa. This would allow me to further my field of specialisation in South Africa within the SKA project in collaboration with MIT and other international networks I would have forged during my graduate studies,’ said Essack.
‘Research is a challenging process with a myriad of positive and negative turns that keep you perpetually motivated in search of solutions. It is ultimately a rewarding journey,’ said Essack.
‘I have been fortunate to learn from and work with world-class researchers in the School of Mathematics, Statistics and Computer Science and the School of Chemistry and Physics at UKZN, who have inspired me and helped me to grow as a scientist and a researcher. I am grateful to have received an education that has allowed me to compete at an international level in my field.’
Professor Kavilan Moodley, of UKZN’s Astrophysics and Cosmology Research Unit said: ‘Zahra was involved in original research in developing an independent technique to extract transiting exoplanets from Kepler light curve data. Kepler has revolutionised the field of exoplanet research and Zahra’s successful analysis of this data demonstrates her competence with research methods and their application in this field.’
Dr Matt Hilton (senior lecturer, MSCS) said: ‘Zahra was a brilliant and hardworking student and it was a pleasure working with her. I wish her all the best for her PhD studies in the United States.’
