Biography
From open systems to open institutions: advancing fundamental science and the communities that make it possible.
He is Professor of Quantum Computing in the School for Data Science and Computational Thinking and Pro Vice-Chancellor for Artificial Intelligence and Quantum Technologies at Stellenbosch University. He also directs the National Institute for Theoretical and Computational Sciences (NITheCS).
He earned his PhD and Habilitation in Theoretical Physics at the University of Freiburg. Before joining Stellenbosch, he was Professor of Theoretical Physics and Pro Vice-Chancellor for Big Data and Informatics at the University of KwaZulu-Natal, where he held the South African Research Chair in Quantum Information Processing and Communication.
His widely cited work includes approximately 250 refereed papers and the monographs The Theory of Open Quantum Systems and Machine Learning with Quantum Computers. He is a fellow of the Academy of Science of South Africa, the Royal Society of South Africa and the African Academy of Sciences, and a recipient of the Stella d’Italia.
Alongside his research, he helps connect institutions across Africa and Europe, co-leading the Africa–Europe Cluster of Research Excellence in AI and Data Science and serving on editorial boards spanning open systems, quantum machine intelligence and scientific publishing.
