Haris Aziz

Scientia Associate Professor
Associate Professor

Haris Aziz is a Scientia Associate Professor at UNSW Sydney, leader of the Algorithmic Decision Theory group, and director of the Sydney EconCS network. His research interests lie at the intersection of artificial intelligence, theoretical computer science and mathematical social sciences ---, especially computational social choice and algorithmic game theory.

Haris is a recipient of the Scientia Fellowship (2018 - ), CORE Chris Wallace Research Excellence Award (2017) and the Julius Career Award (2016 - 2018). In 2015, he was selected by the Institute of Electrical and Electronics Engineers (IEEE) for the AI 10 to Watch List. He was also selected for the Early Career Spotlight list at IJCAI 2016. He is on the board of directors of IFAAMAS and is an associate editor of major journals including AIJ, JAIR, JAAMAS, and Social Choice & Welfare.

His research has been covered by media outlets such as Scientific American, Sydney Morning Herald, The Guardian, Quanta Magazine, Die Zeit and Inside Science. In 2018, he featured in the list of thinkers at the Festival of Dangerous Ideas. In 2020, The Australian newspaper recognized him as the national field leader in game theory and decision sciences in Australia. 

Haris completed his PhD from University of Warwick in 2009, MSc from Oxford University and his BSc (Honours) from Lahore University of Management Sciences. He undertook postdoctoral research at the Ludwig Maximilian University of Munich and Technical University of Munich in Germany. He has held visiting scientist/academic roles at Oxford University, Harvard University, and University Paris Dauphine.
