Research Interests:

I develop novel user interface systems and test these systems with users in the lab or in the fields. I also work on theoretical issues in Human-Computer Interaction (HCI), approaching problems mainly from an applied cognitive science point of view. Specifically, I have worked in the following research areas:

• HCI theory and methodology
• User interface for information management
• Spatial cognition and its applications
• Computer-supported cooperative work
