overview

My research on surface computing explores the use of horizontal interactive displays for a variety of entertainment, educational, and productivity applications. My Ph.D. dissertation, Supporting Effective Interaction with Tabletop Groupware, introduced novel interaction techniques and compared interface designs for supporting co-located group work around computer-augmented tables. Post-Ph.D., I continued to conduct surface research (though this is no longer my primary area of focus): key contributions include research on surface computing systems for productivity tasks, gesture elicitation methodologies, and touchscreen interactions that are accessible to blind users.

Teaching & Service

Jacob O. Wobbrock and I co-taught "Input and Interaction" at the University of Washington during spring quarter 2012. I served as program co-chair for the 2012 ACM conference on Interactive Tabletops & Surfaces (ITS 2012).
