Area of study
The bulk of my research and teaching is on groundwater, both in terms of resources and chemistry, with current research projects on the influence of climate and land-use change on groundwater funded through the Victorian Department of Primary Industries and the National Centre for Groundwater Research and Training. Other research projects focus on improving treatment procedures for acid mine drainage and understanding the formation of acid sulphate soils. My geomorphological interests centre on karst (I have caved extensively in Australia, Papua New Guinea and New Zealand), as well as tectonic geomorphology and the interaction between landscape evolution and human settlement. I have worked on the geomorphology of archaeological sites in Australia, China, Papua New Guinea and New Caledonia. I have published over 130 papers on these topics, as well as supervising 33 PhD students, 4 MSc students and 102 Honours students. I have acted as a consultant on groundwater, contaminated site management and geomorphology of archaeological sites, including as an expert witness.

Possible PhD project - Hydrogeology and hydrogeochemistry
The Miocene Port Campbell Limestone underlies a large part of the western Victorian plains, but outcrops are very limited because where it is not overlain by basalts it is covered by thin Pliocene clays and sands. The limestone has high intergranular permeability but there is also evidence for substantial karstic permeability in the form of extensive doline fields and high transmissivity values intersected in ~3% of bores, although this has been ignored when modelling the groundwater flow in the limestone. Detailed study of a small catchment on the northern margin of the Port Campbell Limestone has shown sufficient leakage of groundwater through a doline to cause the watertable surface to be a closed depression and to strongly decrease surface water flow out of this catchment. The aim of this project is to extend these initial findings and determine the extent of karstic permeability in the limestone, in order to establish the influence that this has on recharge, groundwater flow and the potential for surface contamination, using a combination of bore and surface water data (including geochemistry), remote sensing (particularly LIDAR and Landsat) and geophysical techniques (particularly microgravity).
