My research agenda focuses on the design and evaluation of rich information interfaces in support of complex information seeking and retrieval tasks like exploratory search.

Rich interactive interfaces for exploring search results -- including graphical visual search results thumbnail displays -- are a promising way to improve information interaction, inspired by the success of information visualization for abstract data.

PhotoFinder Kiosk and PhotoFinder Web support collaborative annotation, browsing and search of photos. The SIGCHI PhotoHistory enables members of a community of human-computer interaction (HCI) professionals to enjoy, share and contribute to similar experiences by browsing and annotating photos at an interactive public exhibit and on the web. The design of the user interface for the Kiosk and location of the installation in a communal space encouraged collaborative reflection, storytelling and interpretation of shared experiences.
