As mobile devices become ubiquitous in enterprise and industrial environments, new paradigms of interaction and collaboration are required to enable humans to collaborate with other humans and also with intelligent machines. I've worked on mobile collaboration tools that allow multi-modal, remote collaborative problem-solving between expertise seekers and experts in the enterprise and expert search tools based on social data analytics.
Social and Collaborative search
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 social search, which is the augmentation of Web search activities through social interactions and feedback from social networks. I have studied social Q&A on sites like Twitter and Quora. A related area is collaborative Web search, where people 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 and developed a tool called CoSense. I also studied collaborative sensemaking during search tasks on a table-top surface.
Collaborative Sensemaking and Decision-Making
A challenging aspect of collaborative information tasks is sensemaking. For my dissertation, I studied collaborative sensemaking among healthcare providers in the emergency department of the Penn State Hershey Medical Center. I also studied collaborative sensemaking, information seeking, and decision-making during emergency crisis response.
