Ravi Naidu is the CEO and Managing Director of the Cooperative Research Centre for Contamination Assessment and Remediation of the Environment (CRC CARE), Professor and Global Innovation Chair and Director of the Global Centre for Environmental Remediation at the University of Newcastle, Australia. Prof. Naidu's work focuses on the remediation of contaminated soil, water and air, and the potential impacts of contaminants upon environmental and human health at local, national and global levels. Prof. Naidu been a global leader in the move to the now widely accepted 'risk-based' approach to managing contaminated sites. He has also been a leader in the shift to in situ remediation - cleaning up contamination where it lies, rather than the traditional 'dig and dump' approach. Together, these approaches potentially save industry millions, if not billions, of dollars annually and make clean-up far more feasible and effective. Prof. Naidu received his PhD in environmental science from Massey University, New Zealand. He is an elected Fellow of the Soil Science Societies of America (2000) and New Zealand (2004), and the America Society of Agronomy (2006), and was the founding director of the University of South Australia's Centre for Environmental Risk Assessment and Remediation.
