UP’s Prof Nelishia Pillay is a trailblazing computer scientist who is transforming the technological landscape through artificial intelligence and sustainable development. We learn about her journey.

In the dynamic realm of technological innovation, few academic luminaries shine as brightly as the University of Pretoria’s (UP) Professor Nelishia Pillay, a computer scientist whose journey epitomises intellectual curiosity and determination. Her recent accolade as an Exceptional Academic Achiever at UP is a personal triumph for her, and an inspiration for aspiring researchers and technologists.

Hailing from Pietermaritzburg, Prof Pillay’s academic journey began at the former University of Natal, where she completed her undergraduate, honours and master’s degrees, before transitioning from lecturer to senior academic leader.        

“At school, I loved problem-solving and mathematics,” Prof Pillay says.

Her transformative moment came in Grade 10, when the business magazines her father read opened her eyes to the world of computer science, redirecting her career aspirations of becoming a maths teacher to a more expansive technological landscape.

After lecturing in Durban for six years, she returned to Pietermaritzburg as a senior lecturer and Head of the Computer Science Department at the University of Natal. In 2017, she was appointed as Head of the Computer Science at UP, a role that aligned with her professional ambitions. She now holds the National Research Foundation-Department of Science and Innovation SARChI Chair in Artificial Intelligence for Sustainable Development and the MultiChoice Joint Chair in Machine Learning.

“This is my dream job,” she says, highlighting her passion for leveraging artificial intelligence (AI) towards the Sustainable Development Goals.

Her research focus transcends traditional academic boundaries, as she seeks to create meaningful societal change through technological innovation.

Prof Pillay's achievements extend beyond research. She has mentored several master’s and doctoral students, guiding the next generation of technological pioneers. Her leadership is complemented by diverse interests, from representing South Africa in karate in 2009 and 2010 to enjoying activities like jogging, yoga and nature walks.

“Believe in yourself,” she advises. “It always feels like you can’t do it – until you can.”
