Dr Chris Humphrey – BSc (Hons), PhD
Dr Chris Humprey leads the ERISS Aquatic Ecosystems Protection program. He has a background in freshwater ecology and has spent most of his research career investigating tropical streams of northern Australia. A particular focus of his research has been the development, implementation and refinement of environmental monitoring programs used to assess potential human impacts (including mining) upon freshwater ecosystems. Chris has been involved in national and international river health and remediation programs and has represented the department on a number of scientific committees associated with related programs. He has also authored and played a key technical coordination role in the previous and ongoing revisions of the Australian & New Zealand Water Quality Guidelines. Recent mine-related research includes the development of post-mining closure criteria for both revegetated landforms and freshwater ecosystems.
