Sarah Vieweg’s research interests focus on various dimensions of the study of social media and microblogging, Natural Language Processing (NLP), human-computer interaction (HCI), and Computer-Supported Cooperative Work (CSCW). She is a Scientist with the Social Computing group at the Qatar Computing Research Institute (QCRI). Her work focuses on the use of social media and microblogging services during mass emergency events and humanitarian crises. She frequently incorporates linguistic and sociological theories and methods into her research. Her dissertation, "Situational Awareness in Mass Emergency: A Behavioral and Linguistic Analysis of Microblogged Communications," explores the use of Twitter during mass emergencies with an eye toward creating tools to automatically identify information that contributes to situational awareness. Previously, Sarah worked at Oblong Industries, an innovative company whose technology transforms the way we work, create, and collaborate.
