Biography

Associate Professor Peter Vamplew’s information technology expertise focuses on artificial intelligence, particularly reinforcement learning, neural networks and evolutionary computation.

Dr Vamplew is currently researching variations on reinforcement learning algorithms for multi-objective problems, which contribute to the explainability and safety of autonomous AI systems. Peter’s research has been published widely in highly-ranked international journals.

Peter leads the Federation Learning Agents Group, which focuses on reinforcement learning and related topics. He is an Associate Editor for Neurocomputing journal, and a grant reviewer for the Australia Research Council, the Flanders Research Foundation and the Dutch Research Council.

Peter has been Associate Professor in Information Technology at Federation University Australia since 2014, and was Senior Lecturer at the University of Ballarat (now Federation University) since 2005. Previously he was a lecturer within the computing discipline at the University of Tasmania from 1991–2005, where he received his PhD.
