My primary research interests are in Subsurface Contaminant Hydrology. That includes Contaminant Fate and Transport within the subdisciplines of Hydrogeology (below the water table) and Vadose Zone Hydrology (above the water table). I am particularly interested in the study of multiphase flow and unsaturated flow in porous media, i.e. when more than one fluid is present. My research approach emphasises highly controlled laboratory based experiments to investigate primary mechanisms and processes controlling fluid flow and contaminant transport. In addition, numerical modelling is used to analyse laboratory and field data, design further experiments, and investigate the potential implications of the research results.
This research improves and extends our fundamental understanding of Subsurface Contaminant Hydrology and the technologies used in Groundwater and Soil Contamination Investigations, Monitoring, Simulation, and Remediation.
