Honouring SA’s leading innovators in science, engineering and technology
The National Science and Technology Forum (NSTF) held its prestigious annual NSTF-South32 Awards to honour and recognise outstanding South African contributions to the world of science, engineering and technology (SeT).
South Africa’s first science awards and dubbed the “Science Oscars”, the NSTF-South32 Awards marks the largest SeT and innovation awards in the country. The gala evening celebrating South African ingenuity and excellence took place on Thursday, July 11 and was live-streamed from Johannesburg and Cape Town.
The NSTF Awards was established in 1998 as a collaborative effort to recognise teams, organisations and individuals who have made exceptional efforts in their fields.
“My view is that the future is bright and exciting, if we approach it with open minds and arms. The challenges faced by the world are profound. The threats of unprecedented outbreaks, natural disasters, climate change, drought, energy and
food insecurity, and so on remain priorities demanding the world’s attention and the need to work collaboratively and in partnership,” said Prof Jeffrey Mphahlele, NSTF Chairperson.
“Collectively, we are making progress. Science is at the heart of providing solutions to these myriad challenges. Amid these complexities, the NSTF continues to evolve and remain relevant. It always strives to be a moderate force that participates in public engagements and discourses with a view of shaping and influencing public policies for the benefit of society.
“The call is loud and clear – we need to build a society that looks into the future.”
Showcasing the research and development capacity of South Africa, the NSTF is the most representative multi-stakeholder non-profit forum promoting SeT and innovation.

Guardian of the green world
Prof Ben-Erik van Wyk bridges ancient wisdom and modern science
PrOFeSSOr Ben-erik van Wyk has spent decades unlocking the secrets of indigenous plants. his work in ethnobotany – the traditional uses of plants by local people – is situated at the nexus of cultural heritage and scientific inquiry. As the Chair of the Department of Science and Innovation (DSI)/National research Foundation (NrF) South African research Chairs Initiative (SArChI) in Indigenous Plant Use, Van Wyk’s work straddles the realms of botany, anthropology and cultural preservation. he is studying what he calls “the most ancient of human plant uses” and dealing with “accumulated wisdom about the properties of plants gained through hundreds of thousands of years of trial and error”.
As modernisation creeps into rural areas, traditional plant knowledge is fading fast. Van Wyk sees the urgency in preserving this fragile knowledge, which can easily be lost to future generations if not properly documented. “The botanical and cultural diversity of southern Africa is of importance to all humanity, as it is associated with the very origins of the use of plants by modern humans.”
By bridging ancient wisdom and modern science, Van Wyk’s research opens new avenues for drug discovery, sustainable agriculture and conservation. One of his most profound moments came during a visit to Nieuwoudtville, where an encounter with Koos Paulse, an elderly man of Khoi descent, led to a breakthrough in understanding the medicinal properties of Rafnia Amplexicaulis, which is used by elderly women as a natural hormone replacement therapy.
This collaboration, captured in a documentary, The Professor, exemplifies Van Wyk’s approach of elevating indigenous experts to their rightful place as co-researchers rather than subjects of study. his research has already nurtured several new intellectual leaders from various cultural groups, transforming ethnobotany from a “colonial safari-type adventure” to a dynamic, indigenous-led field.
Growing up in a family of “plant people” offered early exposure to the wonders of botany and set the stage for a lifetime of discovery. “My father was a keen gardener
and my mother a botanical artist. So I practically knew all garden plants from an early age,” he recalls. “I learned that every leaf and every root holds a story; stories as old as humanity itself.”
For Van Wyk, the NSTF-South32 Lifetime Award is a validation of the long-term importance of his work and the profound discoveries associated with indigenous knowledge, which is often overlooked in the rush towards high-tech solutions. “It is not only species threatened with extinction, but also the indigenous knowledge associated with them.”

The biophotonic breakthrough
Prof Patience Mthunzi-Kufa’s work illuminates the future of healthcare
PrOFeSSOr Patience Mthunzi-Kufa, as research Group head for Biophotonics and Manager at the Photonics Centre at the Council for Scientific and Industrial research (CSIr) in South Africa, is harnessing the power of light to detect and combat some of the world’s most pressing health challenges. With her team, she is pushing boundaries to develop cutting edge photonics-based diagnostic devices that could transform point-of-care detection for hIV, tuberculosis, Covid-19 and various non-communicable diseases. “The diverse nature of the work I do drives my passion,” she says, explaining that the research itself is fresh, exciting and cutting edge.
her work represents more than just scientific advancement. It is a beacon of hope for improved healthcare accessibility, particularly in resource-limited settings where rapid, accurate diagnostics can make a life-saving difference.
She’s also pioneering photonics-based tools for bulk screening pharmaceuticals, which could prevent the distribution of substandard medication and potentially save millions of lives worldwide. “Drug safety, efficacy and availability are crucial areas of focus, because with reliable medications people can live long and fulfilled lives.”
her work is underpinned by curiosity and a desire to help others, and her constant probing and passion for problem-solving have led to numerous breakthroughs. “I love being in research because it is flexible, and its fluid nature provides opportunities to stretch oneself while making new discoveries.”
One of the most rewarding aspects of her work is witnessing the success of her students. “It is amazing when parents express gratitude and acknowledge my contribution to a student’s development, and it’s particularly exciting to see postgraduates under my supervision obtain their degrees Cum Laude.”
All research comes with challenges, but she emphasises the importance of stepping back when faced with complex situations. “The secret to obtaining these ‘Aha!’ moments is to take a breather.”
This professor dreams of starting an internationally renowned biophotonics spin-off company. The ambitious goal would serve the double purpose of creating jobs while applying cutting-edge research to various industries, including health, pharmaceuticals, agriculture and beauty.
Mthunzi-Kufa says winning the NSTF-South32 Award for a researcher is an amazing incentive to keep going the extra mile. “I’ve noted how much peer acknowledgement and international attention I’m attracting, which provides crucial strategic positioning for many opportunities going forward,” she says. “Winning also confirms that my family and research team are truly epic – I am because they are!”

The environmental alchemist
Prof Tebogo Mashifana turns waste into wonder
PrOFeSSOr Tebogo Mashifana, at the helm of the Department of Chemical engineering Technology at the University of Johannesburg (UJ), is revolutionising how industrial waste is viewed and treated, while reshaping the landscape of environmental engineering in South Africa and beyond.
“I convert industrial pollutants into new, usable products and employ waste-based solutions for wastewater treatment, aiming for zero waste discharge. We aren’t just managing waste; we’re transforming it into valuable resources.”
Mashifana first witnessed the environmental toll of industrial waste as a graduate metallurgist working in South Africa’s gold mining industry – an experience that ignited a passion that would define her career and solidify her commitment to practical, circular economy solutions. her work has yielded remarkable real-world results, including a provisional patent for using modified waste materials as a substitute for conventional binding agents like cement. her novel waste-to-material approach transforms various waste streams into building materials such as paving blocks, roof tiles and bricks.
“Furthermore, the reliance on locally available waste reduces the need for imported supplies, fostering self-reliance and resilience,” she explains. “Ultimately, this research has the power to advance waste processing technologies, promote sustainable construction practices and contribute solutions to critical housing challenges in SA.”
Looking ahead, Mashifana is excited about the possibilities in sustainable materials, waste beneficiation and knowledge transfer. She’s particularly intrigued by the potential of 3D printing using waste materials, and advancing electronic waste beneficiation. “Prioritising the commercialisation of research findings can lead to job creation and economic development, addressing pressing challenges in SA and the globe. By targeting these multifaceted areas, we can drive transformative advancements in sustainability and create tangible societal impact.”
As she accepts the TW Kambule-NSTF emerging researcher Award, Mashifana remains grounded in her guiding principle to “leave every space better” than she
found it – and to do so with creativity, persistence and patience.
“Pursuing this type of groundbreaking research has taught me the importance of high-quality work and unwavering determination to pave the way for progress, even in the face of adversity.
“This award inspires me to continue pushing the boundaries of innovation, and it is a career-defining achievement that I embrace with great humility.”
To emerging researchers, Mashifana offers a powerful call to action: “Be deeply bothered by the pressing challenges facing our society. Let what keeps you awake at night drive you to investigate innovative solutions.”
Prof Tebogo Mashifana, Head of the Department of Chemical Engineering Technology at UJ.
The visionary leader Prof Bernard Slippers cultivates scientific excellence through team building
AS the Director of the Forestry and Agricultural Biotechnology Institute (FABI) and Innovation Africa and a professor at the University of Pretoria (UP), Professor Bernard Slippers’ mission is to nurture the next generation of researchers and foster scientific excellence through team-based research.
While he is redefining leadership in the scientific community, he believes: “Science and innovation are not the result of a brilliant moment and a brilliant person; it is always an emergent property of an ecosystem in which people work.”
exploring Namibia’s diverse landscapes while he was growing up, Slippers developed a deep fascination with nature and biological diversity. An early passion for everything – “from the sea to the desert, to mushrooms on termite mounds in the Savanna” – was nurtured by his parents, who were both teachers. This led to a career dedicated to not just scientific discovery, but also to building the structures that make groundbreaking research possible. his leadership philosophy emphasises the power of teamwork over mere collaboration. “Collaboration is two athletes running 100m next to each other. Teamwork is like competing for the World Cup and relies on different skills; everyone depends on one another to do their unique part.”
Despite resource challenges in South Africa’s scientific landscape, this approach has been instrumental in FABI’s global competitiveness for over 25 years. Under Slippers’ guidance, the institute collaborates with industry and government, ensuring a real-world impact by bridging the gap between academic research and practical applications – particularly in the forestry and agricultural sectors. recognising the importance of leadership development in science, Slippers encourages young scientists to develop crucial soft skills such as teamwork, communication, problem-solving, emotional intelligence and collective leadership.
“While expecting scientists to help build our organisations and change our world, we are not intentional enough in developing key skills beyond technical work,”
he explains.
This belief was reinforced by his involvement with the Global Young Academy.
“If we want to close the gap between the haves and the have-nots, we must be intentional and build strong, stable platforms and ecosystems for our future generations to work in.”
As he celebrates this recognition, Slippers again acknowledges that scientific leadership is not about individual brilliance.
“I have the best job in the world and this award is a testament to the hard work and dedication of the entire FABI team. This award stems from the ecosystem we’ve built together, where collective excellence can flourish.”
Prof Bernand Slippers, Director of FABI and Innovation Africa at the University of Pretoria.

The aqua innovator
Prof Timothy Dube harnesses AI to revolutionise water management
AT the nexus of hydrology and cutting-edge technology, Professor Timothy Dube leverages the power of artificial intelligence (AI), machine learning and remote sensing to address one of humanity’s most pressing challenges –water scarcity.
his innovative approach is transforming how water resources are monitored, analysed and managed in some of the world’s most vulnerable ecosystems, with remarkable accuracy.
“Technological advancements enable us to respond to environmental changes in real time, optimise water usage and develop predictive models for better resource planning,” Prof Dube explains.
Prof Dube, Director of the Institute for Water Studies at the University of the Western Cape (UWC), is particularly interested in the often overlooked non-perennial rivers (N-Prs) of semi-arid regions. In sub-Saharan Africa, twothirds of rivers are non-perennial, meaning they do not flow all-year round. These intermittent waterways have been historically neglected in research – a problem in an era where climate change threatens local and global water security.
During a field project as an undergraduate student, Dube saw the devastating effects of water scarcity on rural communities. “Witnessing the struggles people faced due to limited access to clean water profoundly impacted me.”
The model developed by Dube and his team estimates water availability within N-Prs with approximately 85% accuracy – a significant development in regions where traditional monitoring methods fall short. “Our goal is to provide decision-makers with the most accurate and up-to-date information possible.
“By harnessing new-generation Sentinel satellite data, we’re able to detect and monitor water resources in ways that were previously impossible; addressing pressing environmental challenges and promoting better water resource management.”
Dube’s work directly informs improved water management practices and supports agricultural planning, drought mitigation and ecosystem conservation. “The
success of this project was technical, but also deeply personal. Witnessing the direct impact of our work on the ground and knowing that our research was contributing to resilient water management practices and resilient communities was profound.”
As a passionate educator, Prof Dube has trained more than 20 postgraduate students in these advanced technologies, nurturing the next generation of water resource experts. “The integration of AI and machine learning into hydrological modelling presents exciting opportunities to improve predictive capabilities and optimise water management strategies.”
Dube says winning the NSTF-Water research Commission (WrC) Award offers more than personal recognition. “It highlights the importance of inter-disciplinary research in addressing complex environmental issues – amplifying its influence and fostering the broader adoption of innovative solutions to global water challenges.”

Challenging outdated and biased diagnostic tools in kidney disease
A NePhrOLOGIST and lecturer in the Department of Internal Medicine in the University of the Witwatersrand (Wits) School of Clinical Medicine, and research Director at the Wits Donald Gordon Medical Centre, Dr June Fabian’s NSTF-SAMrC Clinician-Scientist Award recognises her leadership and co-ordination of the multi-country African research on Kidney Disease (ArK) project.
The ArK project findings challenged outdated, biased and unscientific diagnostic tools – and developed innovative, evidence-grounded methodologies to achieve greater impact in the early detection and management of chronic kidney disease in African populations.
“Kidney disease in Africa remains silent, deadly and misunderstood. To change this, we must develop a strong sustainable network of research excellence in Africa, inform policy that promotes screening and early detection of those with kidney disease, and advocate for access to amazing new drugs that can prevent progression of kidney disease, many of which are coming off patent in the next few years,” Fabian explains.
Fabian is a Wits alumna who first qualified as a pharmacist and transitioned to study medicine. She trained as a physician and then as a nephrologist, and began practicing at the height of the hIV epidemic when there was no access to ArT. Immersed in the epidemic and recognising the need for local data to inform decision-making – such as who to dialyse or not – catalysed her research career, which was initially focused on hIV-associated kidney disease. her doctoral work expanded to understanding the epidemiology of kidney disease in African populations, notably through the ArK project.
Fabian has led the ArK study in South Africa since 2016. She works among rural communities in the Bushbuckridge sub-district of Mpumalanga, where she is integral to the clinical platform team at Wits’ rural campus, officially the SAMrC/Wits rural Public health and health Transitions research Unit (Wits-Agincourt).
“I hope to contribute research that accurately rep-
resents African populations in global science, redresses inequities, and improves human life and the care we provide in Africa and more broadly. I am deeply committed to capacitating the next generation of African scientists to ensure the longevity and expansion of African-centric research programmes,” she says.
“I hope that winning the NSTF-South32 award will help me progress in my career, enhance my credibility and mostly, help me to procure funding and develop collaborations and networks that enable me to do more research that makes a difference, for which I am deeply grateful.”
Dr June Fabian, Director of the Wits Donald Gordon Medical Research Institute.
The resource radical
Prof Linda Godfrey’s quest for a circular South Africa
AS sustainability continues to become a global priority, Professor Linda Godfrey is a pioneering force in circular economy innovation – reshaping how South Africa views its resources and waste.
“Approximately 50% of climate impacts, 90% of biodiversity loss and 90% of water stress comes from the extraction and processing of resources. If we are to address the big planetary crisis facing us, we must rethink our relationship with resources,” Godfrey says.
Godfrey is the Manager of Circular Innovation South Africa (CISA), an initiative of the Department of Science and Innovation (DSI), managed by the Council for Scientific and Industrial research (CSIr). Through CISA, Godfrey implements the DSI’s science, technology and innovation aspirations in the circular economy and leads the charge in transforming the country’s approach to resource use.
She’s guided by two decades of experience in the waste sector. “I’ve seen first-hand how as a society we consume and dispose, and just how much of our waste ends up in landfills or dumpsites,” she reflects.
She says SA has the unique opportunity to leapfrog the resource-intensive growth paths of the global north “to understand the opportunities and constraints provided by our limited resources, and create a more sustainable and regenerative trajectory that provides improved quality of life for all”.
The country already has many examples of circular practices in place. “Perhaps not yet at the scale for meaningful impact, but they’re there. We’ve been doing ‘circular’ for decades; we just never called it that.”
recent developments in this field filled her with excitement and hope. “We’re seeing circular businesses and business models emerge that we would never have dreamt of a decade ago. New policy instruments and innovative new technologies support the efficient and sufficient use of resources, and are decoupling development from resource consumption,” she adds.
Godfrey wears multiple hats – manager, researcher and teacher – and remains committed to a sustainable future.
“Professional success is about making a positive difference, a continuous cycle of learning, sharing and building, impacting how SA manages its resources, including waste.”
Winning the NSTF-South32 Green economy Award holds special meaning. “recognition from peers suggests the work we do has an impact, and also acknowledges the long hours and sacrifices that one makes to build a lasting career in the sciences.”

Sounding the siren for science as solution
AN honorary Adjunct Professor in the School of Mechanical, Industrial and Aeronautical engineering at the University of the Witwatersrand (Wits), Irvy “Igle” Gledhill won the Science Diplomacy for Africa Award, which recognises impactful solutions and/or collaborations for the benefit of South Africa and the African continent.
Gledhill was awarded the accolade for her work to build vibrant, supportive environments in which women and men as scientists can make real contributions. “Scientists and engineers do find a way across political boundaries, because of their overriding common interest in solving challenging problems,” she says.
her leadership contributions include the international Women in Physics working group, the Global Gender Gap Project and convening African and South African scientists to engage with “wicked” problems.
“I’d like to state clearly that science is not a belief system; it’s a process of questions, reasoning and testing. Bias and illusion are quickly discarded. Science is a process of continuous exploration and challenge,” says Gledhill.
Gledhill was born in Makhanda, in the eastern Cape province. She completed her BSc with distinction in physics in 1976, followed by an honours degree in Physics at rhodes University. She completed her PhD in Plasma Physics at the University of Natal (now UKZN). She did her postdoctoral work at the University of California, Los Angeles, on magnetic confinement and plasma simulation, and at Stanford on Space Shuttle physics.
In 2024, rhodes University awarded her a DSc (honoris causa) for her “long and distinguished contribution to research in physics, national and international leadership in physics, and human capital development, particularly regarding women in physics”.
She is Vice-President for International relations and Scientific Affairs of the Network of African Science Academies, interim Vice-President of the Academy of Science of South Africa, and a member of the American Physical Society Committee on International Scientific Affairs. She serves on the SA-UNeSCO Science Sector Committee and the World Cultural Council Interdisciplinary Committee.
“Science diplomacy across Africa is more important than ever before,” says Gledhill. “We are the continent most vulnerable to climate change and we are in the crisis now. Crops are failing. Floods and heatwaves are more frequent. Displacement and migration are rising. We are sounding the warning now: it’s time to adapt and prepare.”

uLwazi Node wins for SAEON Open Data Platform
Advancing availability, management and re-use of research data
The NSTF-South32 Data for research Award was awarded to the uLwazi Node for the SAeON Open Data Platform (ODP).
The award category is granted for advancing the availability, management and re-use of research data.
The SAeON ODP, which is managed by the uLwazi Node, is a metadata repository / data infrastructure that facilitates the FAIr (Findable, Accessible, Interoperable, reusable) publication, discovery, dissemination and preservation of earth observation and environmental data in South Africa.
Portions of the ODP metadata are visible in the Global earth Observation System of Systems (GeOSS) and DataCite. The system also supports national data mobilisation initiatives, including the South African risk and Vulnerability Atlas and the Marine Information Management System, which is co-developed with the Department of Forestry, Fisheries and the environment.
uLwazi, meaning “knowledge”, is one of SAeON’s
seven nodes and was established in 2018 to support data management, the development of information platforms and decision-support tools for government departments. It is comprised of four areas co-ordinated by specialist team leaders in IT infrastructure, data curation, systems development and data science.
Last year, the SAeON ODP was certified as a Trustworthy Data repository by the CoreTrustSeal Standards and Certification Board. This was the result of years of work by the uLwazi Node to ensure that the SAeON ODP was set up and run according to international standards, and led to the SAeON ODP being only the second repository on the African continent to receive the certification. The work put into achieving this certification laid a solid foundation for the SAeON ODP.

NuMerI’s groundbreaking facility reshapes medical research and patient care
The Nuclear Medicine research Infrastructure (NuMerI) represents a paradigm shift in patient care and stands as a testament to South Africa’s cutting-edge scientific prowess.
“We offer a one-stop shop medical imaging and theragnostics facility that is dedicated to drug development and clinical research,” explains NuMerI CeO Professor Mike Sathekge, a renowned nuclear medicine physician.
What sets NuMerI apart is its comprehensive approach, which synergises preclinical imaging, radiopharmaceutical production, translational research, radiobiology, medical physics, clinical molecular imaging and theragnostics under one roof. Theragnostics is a two-pronged approach that uses imaging technologies and targeted therapies to identify and treat diseases like cancer, while also monitoring patient outcomes.
and meticulous project execution. “This required a continuous pour of a specially designed high-density concrete from 80 cement trucks,” Sathekge recalls.
This integration creates a unique ecosystem that spans from “laboratory bench to patient bedside”, adds Prof Sathekge.
NuMerI’s groundbreaking work on prostate cancer treatment using targeted alpha therapy has garnered international recognition and prolonged the lives of patients from all walks of life. “All this research has culminated in a publication earlier this year in The Lancet, one of the top medical journals in the world.”
Sathekge says the establishment of NuMerI also represents a triumph of collaboration, bringing together national partners like NeCSA/NTP, iThemba LABS, the University of Pretoria and Steve Biko Academic hospital. This partnership leverages diverse strengths to benefit patients, students, researchers and the broader economy.

Translating science into action through communication
FOr her involvement in both communicating her own science to the public and training early career researchers in science communication, Professor Jennifer Fitchett won the Communication Award.
her research is situated within the discipline of biometeorology, exploring the impacts of climate change on both the natural environment and human populations. A Professor of Physical Geography in the School of Geography, Archaeology and environmental Studies (GAeS), Fitchett won the award for effectively communicating her science in an accessible way through a science blog, publishing articles in The Conversation Africa and podcasts.
“Science communication has always been an integral component to my scientific process. Communicating our work to a general audience requires us to think it through more thoroughly, and with a more critical eye,” says Fitchett. “Doing so effectively allows science to translate into action.”
In 2022, Fitchett was elected to the South African Young Academy of Science (SAYAS) and signed up to co-edit the blog. In teaching her honours students, Fitchett gives continuous assessment assignments where students produce weekly blog posts related to course content. This inspired several students to start their own blogs.
“It’s very exciting to work with a cohort of young scientists who want to have their voices heard,” she said.
Fitchett graduated with distinction from the University of the Witwatersrand (Wits) and then completed her PhD in Geography with a split-site component at both Wits and University College London. In 2016, she worked as a postdoctoral fellow at the Wits evolutionary Studies Institute, funded by the Department of Science and Innovation (DSI)/National research Foundation (NrF) Centre of excellence for Palaeosciences.
In 2017, she began lecturing at Wits and was promoted to Senior Lecturer in 2018. She became Associate Professor in 2019, full-time Professor in March 2023 and delivered
her inaugural lecture in July 2023.
Fitchett currently serves as the African Councillor of the International Society of Biometeorology, and is the President of the Society of South African Geographers. She is the Associate editor of the South African Journal of Science, and on the editorial board of the International Journal of Biometeorology, Environment and Planning F, The Holocene and Global and Planetary Change.

IDIA team pioneers data-intensive astronomy in South Africa
The Inter-University Institute for Data Intensive Astronomy (IDIA) has won the NSTF-South32 Special Annual Theme Award: Fourth Industrial revolution (4Ir) in South Africa, recognising its pioneering efforts in bridging astronomy and big data.
“Our goal is to build capacity and expertise in data intensive research and enable the SA research community to step forward as global leaders,” explains Prof rob Simmonds, Associate Director for New Technology Initiatives.
Born in 2015, IDIA is the brainchild of three local universities – the University of Cape Town, University of the Western Cape and University of Pretoria – alongside the South African radio Astronomy Observatory (SArAO). IDIA emerged as a collaborative effort in the face of the looming data deluge from projects like MeerKAT and the Square Kilometre Array (SKA).
At the heart of the work is ilifu, an advanced federated cloud infrastructure that has already served more than 400 astronomers and postgraduate students across 12 universities and four national facilities in SA alone. Since 2018, nearly 200 peer-reviewed articles incorporating its infrastructure have been published.
Project Manager Kechil Kirkham describes IDIA as an academic organisation that performs several functions.
“We nurture postgraduates so that they remain engaged and able to contribute to astronomical research. We also mentor software developers and support astronomers in processing their data.”
One of IDIA’s most significant contributions is the development of open-source software tools like CArTA (Cube Analysis and rendering Tool for Astronomy) and iDaVIe-v (immersive Data Visualisation Interactive explorer for volumetric rendering within Virtual reality), reshaping astronomical research and pushing the boundaries of data visualisation.
“Integration with virtual reality (Vr) software is an exciting avenue for visualisation software, which we are actively pursuing through the IDIA Visualisation Lab,” Kirkham says.
Associate Professor Sally Macfarlane, IDIA’s Associate Director for Development and Outreach, says the team is passionate about democratising science and inviting everyone to join the cosmic conversation. “Through innovative outreach programmes, we’re lowering the entry barrier for newcomers to cloud-based big data science, and fostering inclusivity in data science and computing projects.”
The IDIA team sees the NSTF-South32 Special Annual Theme Award: 4Ir in SA as recognition of past achievements and a catalyst for future innovation. “This is a pivotal moment, and we will leverage the publicity and recognition to drive our vision for the country forward –strengthening partnerships, building new collaborations and inspiring the next generation of IDIA’s infrastructure users.”
