I am currently a Vice-Chancellor's Principal Research Fellow, Director of the Centre for Information Discovery and Data Analytics, and Associate Professor (Reader in the UK, Full Professor in North America) at RMIT University in the School of Science (Computer Science).
I am a researcher in the area of Information Retrieval. My current research focuses on building search systems to effectively and efficiently search massive data collections, and understanding how to measure the quality of the answers found. More broadly, I'm interested in Human-driven Data Science and Analytics, which focuses on devising new approaches to transform heterogeneous data collections into knowledge. This might be accomplished through algorithms, data structures, machine learning, distributed computing, statistical modelling, or some combination of all the above.
See my research overview and publications pages for more information.
In 2018, Fernando Diaz and I co-organized the Third Strategic Workshop on Information Retrieval in Lorne (SWIRL), where we discussed the future of IR research. Our primary goal was to revise the IR research manifesto developed at SWIRL2. A preprint of our findings can be found here.
Potential Students and Postdocs
If you are interested in the work we do and wish to pursue a research career,
please read the information included on my
Phd and Postdoc recruiting page to find out more about current
opportunites and selection criteria.
I am interested in taking on an Honours student in 2018/2019 to work on
Learning-to-Rank (Deep Learning), Search Algorithms, Data Structures for
Search, or Data Compression.
An Honours scholarship may be available for suitably qualifed
students working in my group.
Honours students routinely qualify for
PhD scholarships (APA, RTSP, and Vice-Chancellor Scholarships) after completing an Honours degree in my group.
So, if you're interested in learning more about this research opportunity,
please contact me by email so that we can find a time to meet and discuss
