A primary focus of my research is user interfaces for search. I have invented or participated in several well-known search interface projects including Scatter/Gather clustering of search results, TileBars query term visualization, BioText search over the bioscience literature, and the Flamenco project that investigated and the promoted the use of faceted metadata for collection navigation.
The Flamenco project has had a significant impact in industry and practice; interfaces similar in design to Flamenco are now the standard on e-commerce sites, image navigation sites, and library catalog sites, and support for faceted navigation is now standard in search tools (Solr, Elastic search) and content management systems.
In 2009 I published the first academic book on Search User Interfaces with Cambridge University Press, which has generously allowed me to make the book freely available on the web.
