Real-life teaching. Effective content creating.


Welcome to our UJ 4IR in Action article series. Here, we spotlight the transformative power of the Fourth Industrial Revolution through groundbreaking stories of innovation that create significant societal impacts. This dedicated page serves as a vibrant showcase of how UJ is not just part of the 4IR movement but a leader in integrating technology with human-centered development.

Our features range from articles such as the educational innovations of Dr Philip Baron, who extends his classroom through a widely followed YouTube channel, to the life-changing technologies developed by the UJ Process, Energy and Environmental Technology Station (UJ PEETS), which are providing clean drinking water in remote areas through advanced hydropanels.

We also highlight pioneering research such as Yusuf Kewuyemi’s development of nutritious 3D-printed biscuits, representing our commitment to addressing global challenges through local ingenuity.

Here you can also read many more stories about impact through innovation.

These stories exemplify UJ’s mission to utilise cutting-edge technologies for greater good, ensuring that our advancements in AI and other fields are firmly anchored in enhancing human capabilities and improving lives. Experience these narratives and discover the potential of technology to not only change the way we live and learn but also to empower us all in building a more equitable and sustainable world.
