Tshilidzi Marwala-Biography
We the zambaiaminds.com team are so excited to inform you about the Biography of the prominent people in south Africa
Early life and education
Marwala was born at Duthuni Village in the Limpopo Province. He obtained a PhD in artificial intelligence from the University of Cambridge and Bachelor of Science in mechanical engineering from Case Western Reserve University, graduating with a Magna Cum Laude. He attended school at Mbilwi Secondary School and St.John’s College in Johannesburg.
Career
Marwala is the Rector of the United Nations University and UN Under-Secretary-General. Marwala was previously a vice-chancellor and principal of the University of Johannesburg. He was previously the deputy vice chancellor for research and internationalization as well as the dean of engineering at the University of Johannesburg and a professor of electrical engineering at the University of the Witwatersrand. He was a post-doctoral fellow at Imperial College of Science, Technology and Medicine. He served as a trustee of the Nelson Mandela Foundation and on a board of Nedbank.
One of the books he co-authored on modelling interstate conflict has been translated into Chinese by the National Defense Industry Press. His work and opinion have appeared in media such as New Scientist, Time, The Economist, CNN, and BBC. He has also given talks at Rhodes House, Royal Society, Cambridge Union, Harvard’s Berkman Klein Center for Internet & Society and Oxford Union In 2016 Tshilidzi Marwala delivered the Bernard Price Memorial Lecture in South Africa. With Stephen Hawking and Guy Laliberté he was a judge of the YouTube Space Lab competition.
Academic contributions and research
Marwala’s research interests include the theory and application of artificial intelligence to engineering, computer science, finance, economics, social science and medicine. He has made fundamental contributions to engineering science including the development of the concept of pseudo-modal energies, proposing the theory of rational counterfactual thinking, rational opportunity cost and the theory of flexibly bounded rationality He was a co-inventor of the innovative methods of radiation imaging and with Megan Jill Russell as well as David Rubin the artificial larynx. Marwala also observed that the applicability of prospect theory depends on how much artificial intelligence is used to make a decision. He also observed that the more artificial intelligence is used for decision making the more efficient the markets become. For example, if all decisions are made by artificially intelligent machines then the markets will be fully rational. Marwala together with Israeli researcher Daniel Muller mathematically solved the St. Peterburg paradox through the use of the concept of the relative net utility
Marwala together with Evan Hurwitz proposed that there is less level of information asymmetry between two artificial intelligent agents than between two human agents and that the more artificial intelligence there is in the market the less is the volume of trades in the market.[23][24] With Evan Hurwitz, Marwala was the first researcher to build software agents that are able to bluff on playing a game of poker. Tshilidzi Marwala and Evan Hurwitz in their book applied Lewis turning point theory to study the transition of the economy into automated production and identified an equilibrium point (Lewis turning point) where it does not make economic sense to move human labor to automated machines.
