Project summary
Water resource management is one of the greatest challenges facing sustainable agriculture and urban populations across southern Australia. Key players driving catastrophic droughts in southern Australia are the tropical Indian Ocean Dipole and polar Southern Annual Mode climate systems,...

Atmospheric dust plumes can affect global climate, but the impact of Australian dust on climate is poorly known even though it is a major dust source. This project will study the magnetism of dust deposits in marine sediments to understand how Australian dust influences climate in order to better predict the...

The project aims to reconstruct deep water carbonate ion and nutrient contents at millennial timescales using high sedimentation cores from the Atlantic Ocean.

This research is part of an ARC Linkage project. Read more about it in this news story.

Magnetotactic bacteria biomineralise magnetic nanoparticles. They are ubiquitous in aquatic environments, so their inorganic remains (magnetofossils) should give rise to sedimentary palaeomagnetic signals. Ancient magnetofossil identifications were sparse until new techniques recently demonstrated their extensive...

Groundwater is a vital water resource in Australia, and the world, and understanding the dynamics of recharge from and discharge to surface waterways is necessary for using our water resources wisely.
At ANU, we are developing hydrogeochemical methods to understand groundwater dynamics, including...

The magnetism of sediments provides information on the past behaviour of the Earth's magnetic field. This project will study sediments from the oceans around Australia to understand how the field was recorded and use this information to construct a new generation of computer models that will provide insights into...

Rates of soil formation in North Queensland are being studied on basalt lava flows which are dated by K/Ar. In the semi-arid Hughenden- Charters Towers region (500-600 mm/year rainfall), soils form at rates of ~0.3 mm/1000 years. On the Atherton Tableland, (rainfall 1200-3500 mm/year) rates are significantly faster...

Magnetic minerals are almost ubiquitous in nature, which means magnetic techniques can be used to understand Earth’s magnetic field and deep-Earth dynamo processes, and act as proxies for system processes in palaeoclimate, paleoceanography, pollution tracing, and archaeology.

Research supports
The group has funding to support one highly motivated PhD student, based on competition of applicants (academic background, research ideas, etc). Contact me if you are interested.
We also welcome candidates who can raise fund (e.g., China Scholarship Council,...

This project addresses the pressing need to understand the growing disequilibrium between today’s fast climate changes and slow ice-volume adjustments, which is significant because this is a key determinant for potential acceleration of sea-level rise. This is a major concern to society, because climate change and...

Figure 1. The tropical waters around Indonesia are an important source region for Australia’s rainfall.
The warm tropical waters around Indonesia are an important source of rainfall for Australia. When the temperature of the water in this area is warmer than usual Australia receives more rain...

Paleogeographic reconstructions indicate that parts of the Australian continent have been exposed above sea level for hundreds of millions of years. Paleomagnetic dating of giant weathering profiles (up to 100 m deep) in open pit mines reveals three major periods of deep oxidation: Late Cenozoic (20 Ma to present...
