David joined The University of Queensland in 2001 as Director of the newly established Centre for Social Responsibility in Mining (CSRM), one of six organisational units comprising the Sustainable Minerals Institute (SMI). Under David’s leadership, CSRM became a leading global centre for applied research and professional education relating to social performance management in the mining and minerals sector.

In 2012 David moved into a Deputy Director role in the SMI, with responsibility for driving cross-disciplinary research initiatives to address the technical, environmental and social dimensions of mining and sustainability. He retired from the University in July 2016 but continues to be active as a researcher and consultant.

For the first half of 2017 he was based in Lima, Peru, where he worked with the Universidad del Pacifico to build a research capability in mining and sustainability. In 2019 he led the development of a new mining engineering curriculum for the Western Australia School of Mines (Curtin University).

In 2020 he was engaged by the Global Tailings Review to edit a compendium of research papers and commentaries to accompany the release of the Global Tailings Standard. David is a graduate of the University of Melbourne and holds a PhD in Political Science from Stanford University.
