He is a practitioner in the field now often called, ‘Communities & Social Performance’. His company, Yirri Global LLC, assists companies in due diligence assessments, stakeholder engagement, social impact assessments and building capacity internally with training, developing standards, systems and processes to improve engagement, communication and relationships between host communities and a project or operation, especially when Indigenous peoples are part of the latter's context.

He has worked during his mining career in some 14 countries, including Ghana, Brazil, Turkey, Indonesia, Mongolia, Canada, the United States, Mexico, Uzbekistan, Peru and others. He teaches at the Colorado School of Mines and is a member of the Advisory Board for the Centre for Social Responsibility in Mining at the Sustainable Minerals Institute at the University of Queensland.
