I'm an Information Retrieval researcher based in Canberra, Australia. From 19 Nov 2013 I am an Applied Researcher in the Bing (Microsoft) team.
My interests lie in the areas of Enterprise and Web Search. I am interested in search evaluation in realistic contexts, distributed search techniques, retrieval through textual annotations, enterprise/intranet search, query suggestion and improvement, improvement of search through exploitation of context, personal search and search efficiency.
I am a member of the editorial board for the Information Retrieval journal (INRT). and hold an adjunct professorship in the College of Engineering and Computer Science at the Australian National University where I continue to advise PhD and other research students.
From 2008 to 2013 I worked at the Funnelback enterprise search company in the role of Chief Scientist.
Between 1998 and 2008 I was a research scientist at CSIRO.
From 1996 to 2003 I was a
coordinator of VLC and Web tracks in the
annual Text Retrieval Conference
(TREC). The activities of these tracks are summarised in

Canberra is an amazingly good place for cycling with good weather and hundreds of kilometres of dedicated cycle paths both on and off road. Riding around the lakes and forests at weekends and on summer evenings is very pleasant.
