Research & Current Projects


Professor Emma Johnston is Pro Vice-Chancellor (Reserach) at the University of New South Wales and head of the Applied Marine and Estuarine Ecology Lab (AMEE). Her group investigates the ecology of human impacts in marine systems. She combines the diverse disciplines of ecology, microbiology and ecotoxicology in an exciting research program that expands our fundamental understanding and provides recommendations for management. Her research is conducted in such diverse field environments as Antarctica, the Great Barrier Reef and temperate Australian estuaries.

Professor Johnston’s work has met the highest standards of international research, as evidenced by more than 90 peer-reviewed publications. She is a television presenter for BBC/Foxtel and Vice President of Science and Technology Australia. Professor Johnston contributes expert opinion to state, federal & international government agencies and consults with industry through the development and implementation of environmental monitoring programs.

She leads a large and friendly research group that includes postdocs, research assistants and students at all levels (PhD, Masters, Honours and undergraduates). They approach their research from both an ecological and ecotoxicological perspective using field experimentation wherever possible.

Major Research Themes

Estuarine Health
Estuaries are widely considered the most impacted of all marine habitats, and more than half of Australian estuaries are disturbed by anthropogenic activities to some degree. Most are subject to combinations of stressors from industry, agriculture, urbanisation and coastal development. This program aims to identify processes and interactions that drive impacts in an effort to develop targeted and effective management strategies to conserve biodiversity in these systems

Antarctic Marine Communities
Antarctica is no longer considered a pristine environment and the impact of human activity is likely to increase in coming years. This project compares the vulnerability of Antarctic assemblages to those of other regions and provides information on the responses of individuals, populations and communities to environmental stressors.

Marine Biological Invasions
This program aims to determine the major drivers of marine bioinvasions. We investigate whether disturbance facilitates the colonisation, persistence or spread of non-native species and how biological diversity modifies this response.
