Areas of Research

I lead the Graph Research Lab and the Database Group at the School of Computing, ANU. My research broadly lies in the areas of databases, data mining, graph algorithms and machine learning. I am interested in understanding theoretical aspects of data management and analysis, and exploring their potential in supporting practitioners.

• Graph algorithms and learning;
• Data management and analysis;
• Data integration (entity resolution, schema matching);
• Data mining.

The Graph Research Lab and the Database Group are seeking bright, enthusiastic doctoral students. Potential applicants may contact me with your CV and academic transcripts. The scholarship is a tax-free allowance of AUD 28,854 per year, tenable for a maximum of 3.5 years.
