Areas of research
Environmental earth science
The Department of Environmental Sciences is a leading centre for the study of earth surface processes and geomorphology in river, wetland, coast, desert and polar environments. Our academic and postgraduate student research (MRes and PhD) is concentrated in four main, interrelated areas;
- Geomorphology and landscape evolution,
- Quaternary environmental change,
- Human impacts on the environment,
- Environmental Management.
We place a strong emphasis on fieldwork and laboratory work and have cross-departmental and cross-institutional research collaborations with colleagues in the fields of biology, climate science, geochronology and earth system science.
Our research also relates to key aspects of environmental management, and collaborative research and student supervision is carried out with industry in addition to domestic and international scientists.

- produced water quality and treatment (Professor Damian Gore, Dr Peter Davies, Dr Shuaifei Zhao).
Research in mature and developing technologies underpins decision making and risk assessments, but also the promotion of innovative and sustainable solutions. This includes:
- beneficial use of waste materials in agriculture and biofuels (Professor Vlad Strezov, Professor Peter Nelson),
- the catalytic removal of organics and CO2 from process and waste streams (Jiang),
- and solutions to the environmental impact of produced water spills (Professor Mark Taylor).

- mercury analysis,
- a mobile laboratory as part of the Environmental Quality laboratory.
Coastal and marine
The Department of Environmental Sciences conducts research in marine, coastal and estuarine science, including:
- the Marine Climate Risk Group led by Associate Professor Ian Goodwin,
- Dr Shari Gallop's research into beach morphodynamics,
- Professor Neil Saintilan’s work on coastal wetlands, climate change and sea-level rise, and
- Maina Mbui research on the application of spatial information science to coastal and marine decision making.
The department is heavily engaged with the Sydney Institute of Marine Science (SIMS) in the SIMS/NSW OEH Coastal Processes Research Node. The Department is an active member of the Macquarie Marine Research Centre.
The Department’s coastal and marine science expertise is integrated into parts of its undergraduate and postgraduate teaching programs, including the Bachelor of Marine Science. Specific research foci include:
- Inner Continental Shelf-Shoreface sediment exchanges
- East Australian Current shelf upwelling and sand transport
- East Australian longshore sand transport system
- Headland sand bypassing processes
- Large-scale coastal response to wave climate change and sea-level change
- Coastal wetland responses to sea-level rise
- Tidal inlet dynamics – forced vs unforced behaviour
- Ocean wave measurement arrays and nearshore coastal modelling
- Coastal engineering impacts on sand transport and estuarine inlets
- Evolution of the eastern Australian coast over the past 2000 years
- Fusion of geohistorical and instrumental coastal data for coastal hazard risk assessment

Coastal and marine research is supported by equipment which includes boats, a jet ski, ground penetrating radar and a range of current monitoring equipment.
The Department’s areas of research are supported by specialist expertise in the cross-cutting themes of:
Spatial information science
Spatial information science is the science of geographic information systems (GIS) and remote-sensing for data storage, visualisation (mapping), and the provision of information to support decision making. It is concerned with the interpretation and analysis of geographical information from a variety of sources and in a range of application fields.
Research in spatial information science
The Department of Environmental Sciences undertakes research using geospatial technologies, including remote sensing (both passive and active sensors) and geographic information systems, spatial modelling and multi-objective (conservation planning) decision support systems. Our goal is to inform the management of Australia’s environment through innovative and interdisciplinary research. Major themes of Michael and Maina’s research are:
- Multispectral and hyperspectral remote sensing for vegetation mapping
- Radar remote sensing for land surface monitoring and terrain modelling
- Spatial predictions of coastal and marine features
- Cumulative impact and risk assessments in geographic information systems (GIS)
- Cross-cultural participatory mapping
- Conservation planning
Teaching and Learning in Spatial Information Science
Spatial information science is a major growth industry. Macquarie University graduates with expertise in spatial information science contribute to diverse workplaces and research fields, including natural resource management, local government, emergency management, land administration, forestry, agriculture, marine environments, health, defence, education, infrastructure management, transport and more. Our undergraduate and postgraduate units focus on practical work to enhance the development of technical skills and problem solving abilities. We provide training with the latest geospatial software, including ArcGIS and ENVI.
Our undergraduate units provide students with a comprehensive understanding of geospatial technologies, including geographic information systems (GIS) and remote sensing. Students learn core concepts and develop technical skills in data acquisition and management, mapping and spatial sampling and analysis. The undergraduate units include:

Major in Spatial Information Science
Spatial information science is a Qualifying Major in the Bachelor of Science and Bachelor of Environment. The aim of the major is to provide students with expertise in the development, management, application and display of spatial information through core studies in:
- geographic information systems (GIS),
- global positioning systems,
- geospatial analysis and modelling, and
- remote sensing.
The major includes core units that engender a depth of knowledge in spatial information science that is immediately transferable to the workplace. In addition, students are given the opportunity to select optional units to extend this knowledge in specific application fields.
Our postgraduate units provide students with an advanced understanding of geospatial technologies, including geographic information systems (GIS) and remote sensing. The postgraduate units include:
- ENV808 Introduction to Geographic Science for Postgraduates (Convenor: Dr Maina Mbui)
