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. The research question I'm exploring is "How are people using their online social networks to fulfill their information needs?"
I have conducted two studies of information seeking in online social networks, The first study analyzed Q&A behavior on Twitter. The other study examined reputation and authority on social Q&A site 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 users make sense of search results found during collaborative Web search tasks with Merrie Morris at Microsoft Research, Redmond, WA.
We studied how groups find, share, and made sense of information using a collaborative Web search tool called SearchTogether. I developed a visualization tool, CoSense, that helps visualize information found during collaborative Web search tasks.

Understanding and Supporting Collaborative 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. A challenging aspect of the work of doctors, nurses, and other clinical and non-clinical staff in the emergency department is making sense of dynamic and unfamiliar situations using a variety of information sources. I drew on my ethnographic study to provide insights into how interfaces can be designed to support sensemaking during collaborative information seeking tasks.

Collaborative Information Seeking, Information Sharing, and Group Decision-Making
Traditionally, information seeking has been considered an individual acitivity but 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.
