Peter is a Fellow of the Royal Academy of Engineering, a Fellow of the Australian Academy of Technology and Engineering, a past President of the Institution of Mining and Metallurgy (now the Institute of Materials, Minerals and Mining); past President of the Australian Council of Engineering Deans and Chair of the Group of Eight Engineering Deans and Associates. In 2012 he completed an eight-year appointment as Executive Dean of the Faculty of Engineering, Computer and Mathematical Sciences at the University of Adelaide followed by a three-year term as Executive Director of Mining Education Australia. He is currently Professor of Mining Engineering at the University of Adelaide and Director designate of the ARC Industrial Transformation Training Centre for Integrated Operations for Complex Resources.
His research includes the spatial modelling, estimation and simulation of geological variables and structures; modelling and prediction in mineral resource, petroleum reservoir and environmental applications; and stochastic modelling and quantified risk assessment in natural resource and environmental applications. Recent work has focussed on the characterisation of rock masses for hot dry rock enhanced geothermal systems and for environmental risk analysis and assessment; the in-situ recovery of copper; geometallurgical modelling; and the stochastic modelling of flow pathways in karst aquifers.
