Research

In my research, I study how the interfaces, interaction techniques, and context-aware infrastructures at the foundation of the next generation of computing systems can better respond to the critical, real-world challenges associated with information overload. Because overload can take many different forms, I have examined and addressed breakdowns in multitasking (overload of attention), information sharing (overload of communications channels), and long-term/archival information storage (overload of electronic organizational systems). What makes my research unique within the domains of HCI and personal information management is that I take two, complementary approaches in my work:

  • I conduct qualitative and quantitative empirical studies of people's real-world information management practices and strategies for managing information overload. Using cognitive theories as an analytic lens, I use these empirical findings to inform the design of novel interfaces and systems.
  • I design, implement, and perform in situ evaluations of interfaces, interaction techniques, and context-aware infrastructures for mitigating information overload. This research involves re-envisioning fundamental characteristics of personal computing, including the ways that underlying data—both user-generated information artifacts and passively captured metadata—are represented and the interaction metaphors that frame the user experience. In my research, I focus on building robust systems that can be deployed and evaluated in the real world, with representative users using their own data and over extended periods of time, which is essential for studying the ways that these tools affect people’s personal information management practices.
