PhD, University of Sydney 1988. Surfaces and pedological features associated with planar pores, channels, chambers, vesicles and cavities.

Dr Leigh Sullivan is a founding Director of Southern Cross Geoscience and Professor of GeoScience. His research interests embrace:

  • the geochemistry of soils and sediments
  • reducing global CO2 emissions by enhancing secure carbon biosequestration via silica phytolith carbon in crops, pastures, forestry and horticulture, and
  • the geochemistry of silica and phosphorus in terrestrial environments.

Many of Leigh's contributions in soil science have been in the area of acid sulfate soil science and management, but they also cover soil organic matter characterisation and dynamics, clay movement in soil, the effect of microstructure on soil behaviour, and the micromorphology and mineralogy of many soil components.

Leigh has co-pioneered research in the role of plantstones (aka. silica phytoliths) in crops, pastures and trees to enhance the secure biosequestration of terrestrial carbon.

Leigh has authored over 300 scientific publications, and has won in excess of $7 million dollars of competitive funding in the past 5 years to support his research.
