PhD Research

David commenced a full-time PhD with the Australian National University (ANU) in mid-2011 to pursue semantic data mining and machine learning methods for knowledge discovery in Description Logic knowledge bases. As part of this research, David is developing OWL Miner, a Java-based tool for performing subgroup discovery over RDF-based data sets which are described and constrained by OWL ontologies.


  • Integrated Water Information Systems (IWIS)


David joined the e-Services Integration (eSI) group with CSIRO in 2004 to develop data and web service composition planning technologies for the Wedgetail (DFDMSA) and Boeing EDKMS projects. David has since focussed on applying semantic technologies to workflow validation, ontology-driven data integration and exchange and ontology engineering, most recently in the area of water data management as part of research undertaken for the Water Information Research and Development Alliance (WIRADA).
