Social Search and Social Q&A
With the popularity of social networking sites like Facebook and Twitter, people are increasingly turning to their online social networks to fulfill their information needs. I am interested in the broad area of social search, which is the augmentation of Web search activities through social interactions and feedback from social networks. Two studies I conducted in this area include analyzing Q&A behavior on Twitter and examining reputation-building and authority on Quora.

Collaborative Web Search
People often search Web sites collaboratively for tasks like planning a family vacation or finding health care information. I studied how groups find, share, and made sense of information during a collaborative Web search task. I developed a visualization tool, CoSense, that helps visualize information found during collaborative Web search tasks.

A challenging aspect of collaborative information tasks is sensemaking. For my dissertation, I conducted an ethnographic study of collaborative sensemaking among healthcare providers in the emergency department of the Penn State Hershey Medical Center. I also studied collaborative sensemaking during search tasks on table-top surfaces.

Collaborative Information Seeking and Sharing
In recent years, researchers have uncovered the collaborative nature of information seeking in domains ranging from library use to hospital intensive care units. I have studied how groups find, seek, share, and use information, especially in the healthcare domain.
