Research Interests   Keywords that apply to my work:  

My main area of research interest concerns the design of collaborative, computer-based museum exhibits. As a human-computer interaction researcher interested in facilitating collaborative learning, exhibits provide a unique high-stakes "crucible" for testing the ability of an interaction design to engage learners with the exhibit content and with one another. If you don't get it right, visitors just walk away. My designs, often developed in collaboration with domain experts, tend to employ emerging interactive technologies so as to make challenging concepts or phenomena more accessible to novice learners. I have also done a great deal of work with mobile devices, both in informal learning contexts (where the mobile devices act as Opportunistic User Interfaces to computer-based exhibits) and in formal contexts (where the mobile devices are used in the context of small-group collaborative classroom activities). I am interested in the ways in which user interface design can be used to scaffold collaborative learning processes. I am also interested in making complex systems simulations more accessible to learners: via the selection of appropriate technologies, the design of the user interface, and the activity design.
