Behind Johannesburg’s title as a world-class African city lies Wits and UJ transforming the city into Africa’s intellectual powerhouse.
- Every lab, start-up and innovation hub is part of Johannesburg’s knowledge.
- Together, the University of the Witwatersrand (Wits)and the University of Johannesburg(UJ) represent both prestige and purpose. One drives global excellence, the other ensures progress is inclusive and grounded in local realities.
- University expertise is embedded in municipal development, bridging knowledge with real-world governance.
As “Joburgers” would say in Setswana: “Joburg ke country,” meaning Johannesburg is a country. A city that feels like a nation itself, whose name echoes with the roar of commerce. For over a century, its identity has been forged in the deep-level gold mines beneath its tall buildings. It is South Africa’s economic and commercial epicentre, a city built on tangible assets. But the gold of the 21st century isn’t dug from the ground, it is cultivated in lecture halls, coded in digital hubs and debated in policy forums. Today, Johannesburg’s claim as a world-class African city is redefined not only by its physical infrastructure, but by a formidable concentration of intellectual capital.
Walking through Braamfontein, the heartbeat of Johannesburg feels close to the surface. The streets are alive with the sound of taxis hooting, car guards filling the area at parking lots, and groups of students in Wits hoodies spilling onto Jorissen Street, cracking jokes and bursting into laughter. Wits University is at the centre of it all, its sandstone buildings rising between the city’s noise and ambition[Ed1] .
Barely five kilometres from inner-city Braamfontein away is the suburb of Auckland Park, where the University of Johannesburg (UJ) beats with its own rhythm. The atmosphere shifts from inner-city street buzz to a campus alive with experimentation. Young innovators huddle as they test prototypes and plan start-ups.
More than just neighbours, the universities are the twin engines of a thriving knowledge economy, providing a growing density of research, innovation and talent. Their combined influence transforms the city into a knowledge economy, where ideas are currency, and innovation is the infrastructure.
Pillars of a knowledge city
Unlike some African cities which dominated by a single major university, Wits and UJ complement each other rather than compete. While Wits University delivers globally benchmarked research, UJ leads in socially embedded innovation. This unique dynamic is validated by the world’s most respected university ranking systems.
Wits University is ranked number 267 in the world, and second in Africa, according to the 2025 QS World University Rankings. Long celebrated for its groundbreaking research, and alumni who’ve shaped South Africa’s story, Wits continues to hold its own among the world’s best.
“From my point of view, rankings are important because institutions want to do well, it is what people see first. We participate in rankings where research is a major component, because that is the hallmark of a good university,” said Wits Deputy Vice-Chancellor, Professor Lynn Morris.
The University of Johannesburg is redefining what an African institution can be, claiming the number 23 spot globally in the 2025 Times Higher Education (THE) Impact Rankings, and an impressive number two in the world for progress in the United Nations’ Sustainable Development Goal (SDGs) toward eradicating poverty.
Together, Wits and UJ form the intellectual backbone of Johannesburg. Universities whose ideas don’t stay trapped in ivory towers but spill into the city streets, innovation hubs and communities.
The deep science engine: Wits
Founded in 1922, Wits University is Johannesburg’s oldest and arguably most prestigious university. A beacon of deep research and frontier science. With over 380 NRF-rated researchers, its labs have birthed discoveries from mining engineering to quantum computing.
Wits Quantum Initiative, the first of its kind in Africa, positions the university at the cutting edge of subatomic physics and computational research. During the COVID-19 pandemic, Wits scientists collaborated across disciplines, from epidemiology to data analytics, demonstrating the university’s capacity for rapid, high-impact innovation.
Under its Wits 2033 strategic plan, the university aims to cement its identity as a research-intensive, globally engaged African leader. The plan envisions Wits as a bridge between Global South and North, a hub for scientific collaboration that also speaks to local realities.
Innovation with social purpose: UJ
While Wits chases the stars of scientific prestige, the University of Johannesburg grounds innovation in human impact. UJ’s philosophy is clear: research must solve problems.
Its Strategic Plan 2035, “Reimagining the Future. Realising Possibility” aligns the university’s goals with the UN’s Sustainable Development Agenda. The result is an institution where inclusivity and integrity are baked into the research DNA. With research productivity of 2.35 accredited output units per scholar (double the national average). UJ turns efficiency into impact.
This academic prowess is not confined to campus grounds. Both universities have built powerful, dedicated innovation hubs that act as direct channels for executing economic and social policy, turning abstract knowledge into jobs, businesses and solutions.
Wits and the digital heartbeat of the inner city
Built on the site of a former print works, Tshimologong Digital Innovation Precinct buzzes with coders, designers and start-ups. It’s not just a space, it’s a policy instrument, part of Johannesburg’s broader urban regeneration strategy. With its name meaning “new beginnings” in Setswana, the precinct operates on three pillars: Digital Skills Development, Incubation & Acceleration, and Market Access. Tshimologong is Wits’s engine for commercializing digital innovation.
I visited the precinct late one afternoon and was immediately greeted by a cheerful administrator, who called for executive assistant Kgaugelo Modiba to assist me. “Don’t be nervous,” Modiba reassured me, as I prepared to interview the initiative’s CEO Mark Harris.
A few people sat nearby in the café area, eyes hooked on laptops, making the most of the precinct’s quiet hum and free Wi-Fi. It was exactly how Prof. Morris described it, “you should visit the precinct, it is a rather refreshing space where everyone is welcome. You can grab coffee and enjoy perks of free Wi-Fi.”
Kgaugelo led me down a corridor into a boardroom flooded with natural light. Tshimologong CEO Mark Harris greeted me with a glass of water and an easy smile. It seems conversations for the people at the precinct come easily. “So what kind of journalist are you going to be? The good kind or the bad one,” Harris laughed.
I asked Harris why Tshimologong had been placed in the heart of Braamfontein, and his answer echoed the vision of the late Professor Barry Dwolatzky (founder of Tshimologong), which was that young people hold the creativity, energy and reason to build a new South Africa. Braamfontein was chosen because its streets are alive with students and young creators.
“The vision was to spot people like yourself who are educated and ambitious, create space for them to become entrepreneurs,” said Harris.
The precinct was never meant to sit safely inside the university walls, but to stand open to all youth, educated, self-taught and anyone with the will to innovate and build.
Tshimologong’s Digital Skills Academy is a crucial accelerator, taking high-potential youth and equipping them with job-ready skills in Artificial Intelligence, Machine Learning and the Internet of Things; the core competencies of the Fourth Industrial Revolution (4IR).
This isn’t just for the sake of training, the precinct works with corporate partners on Enterprise Supplier Development (ESD) programs. These aim to secure employment through its network, creating a direct pipeline from the classrooms to the economy.
“From what I’ve seen of the youngsters who come here, these are people who want to make an impact. Our trainers are just as committed, they are determined to empower future entrepreneurs. The youth are showing up positively, they are hungry for change, and they want to help South Africa grow. We often hear the negative stories about crime and violence, but I refuse to only see that side. There is so much potential here, and I believe in them,” said Harris.
As the discussion continued to unfold, it moved beyond Braamfontein’s physical space to the culture it nurtures. Harris’s belief in the potential of young people seem to find its proof just outside the boardroom walls.
This spirit is best captured by the Fak’ugesi African Digital Innovation Festival, hosted at Tshimologong every year. This festival turns Braamfontein into a pulsing circuit of creativity. The 2025 edition, themed #PowerSurge, called on Africa’s digital creators to “take control on the grid”, blending ancestral intelligence with artificial intelligence.
Walking through the entrance felt like stepping into an animated scene. Walls alive with colour, music weaving between exhibition stands and a soft buzz of conversation rising from every corner. A row of Virtual Reality headsets lined one side of the room, where groups of young people tested immersive worlds. Up the staircase were two small rooms that had been turned into gaming rooms, complete with PS5 and Xbox consoles that drew clusters of gamers competing in friendly matches.
Panels of speakers shared stories of small start-up creators and local digital enterprises. Every corner felt like a classroom and playground combined, a space where learning, creativity and collaboration merged.
“When I curated #PowerSurge I looked at what is currently happening in the African digital continent, we saw last year in 2024, about 65 billion Rands worth of investments that went into start-up, technology and creative sectors,” said the director of Fak’ugesi festival, Alby Michaels. “This year we wanted to showcase what is next in the African continent. We have been creating this beautiful content for our creators for years, but I think now it was all about owning up agencies, standing together and moving forward with purpose.”
Through such initiatives, Johannesburg asserts itself not merely as a consumer of global tech, but as a producer of digital culture and creativity, solidifying its reputation as a continental innovation capital.
“Creators are doing amazing stuff, we are not just consumers of the digital space we are actually critics of those spaces,” said Michaels.

CALSTEAM: UJ’s Future-of-Learning Lab
UJ’s Centre for Advanced Learning Technologies in Science, Technology, Engineering, Arts and Mathematics (CALSTEAM) redefines how the next generation learns.
Instead of chalk and paper, lessons unfold through virtual and augmented reality (VR/AR), tools designed to make abstract science visible and alive. “VR allows students to step inside the science,” explained Professor Mafor Penn, who leads research at the centre. “Concepts like molecules, cells and sound waves suddenly become visible, something you can interact with rather than just imagine.”
Concepts like molecules, cells and sound waves suddenly become visible, something you can interact with rather than just imagine.
CALSTEAM evolved from UJ’s former VARSTEME hub, broadening its focus to include the arts and entrepreneurship. Its mission is not only to enhance teaching but to cultivate educators who are also innovators. Teachers who can create, adapt and apply technology to suit local contexts.
For many South African schools where resources remain scarce, CALSTEAM is deliberate about accessibility. Many of its tools are designed for affordability, ensuring that immersive learning is not limited to well-resourced schools. “We don’t want to widen the gap between those who have and those who don’t,” said Penn. “That’s why we work with scalable, low-cost technologies that can be used anywhere, even in under-resourced classrooms.”
The centre’s pioneering project, Culturally Anchored Virtual and Augmented Reality Simulations (CAVARS), takes this philosophy further by merging indigenous knowledge systems with science education. In one simulation, African drumming demonstrates sound waves, turning cultural practice into scientific inquiry. “Science should never feel foreign,” Penn added. “When learners see their heritage reflected in what they study, it becomes meaningful and memorable.”
Through coding clubs, immersive learning workshops, and postgraduate programmes in Educational Technology, CALSTEAM envisions a future where learning is not confined to textbooks but expands into virtual space, interactive, inclusive, and distinctly African.
Hardwiring Academia into the city’s DNA
A true world-class city does not just produce knowledge, it governs through it. The Gauteng City-Region Observatory (GCRO) is the institutional glue that connects Wits, UJ and the Gauteng Provincial Government. This is not a case of academia simply advising from the sidelines, it is a deep, structural partnership.
“The GCRO is an important research unit that provides data to the provincial government to help them understand and know where to place their resources, to know what interventions to look at, plan and think about the health of the city. “Wits and UJ also plays part and contribute to providing evidence and the data needed”, said Prof. Morris.
Binding the partnership together is the Quality of Life Survey, a mirror reflecting how Johannesburg’s residents navigate the promises and pressures of city life. From employment and housing to public transport and social cohesion. The survey provides policymakers and researchers with a shared lens on how people actually experience the city. “Our work has to have both the rigorous foundation and approach of academics, but be structured in a way that could be useful to policy makers. So, questions are tailored to what problems we see in Johannesburg region and how they could be academically rigorous to answering those questions,” said GCRO researcher, Jason Bell. “Wits and UJ are historic centres of debate, discussion, knowledge generation. They play an active role in the ecosystem of policy identification.”
The road ahead
Both institutions have formalized their future through long-term strategies, Wits 2033 and UJ 2035, each mapping a decade of sustained excellence.
Wits aims to strengthen its position as the leading research university in the Global South, while UJ envisions itself as the model of inclusive innovation. Their combined trajectories ensure that Johannesburg’s intellectual ecosystem remains globally competitive and locally transformative. If executed, these roadmaps could make Johannesburg the continental capital of knowledge innovation, leading Africa into the Fourth Industrial Revolution (4IR).
“People want to see more than just the research, they want to see that the research is actually deployed. Whether it is a new of doing things, a new product or a new device, something tangible, an improved process,” said Morris.
The city that thinks
In small, ordinary moments, a lecture’s spark, a student’s first breakthrough, a start-up’s first pitch, Johannesburg’s new gold is being mined.
Through innovation hubs that drive economic growth and educational equity, and a unique governance model that embeds their expertise into the very fabric of the city, these two universities are doing more than just educating students. They are actively building a more resilient, prosperous, and innovative Johannesburg—a true world-class African city for the 21st century.
