A picture of Rob Rob Capra
My research interests lie at the intersection of human-computer interaction and information retrieval. I work on projects related to interactive information retrieval, search interfaces, and personal information management. My work is unified by an interest in how people find, refind, manage and share information, and how technology can help support these tasks.
