Sarah Vieweg focuses on various dimensions of the study of social media and microblogging, human-computer interaction (HCI), and Computer-Supported Cooperative Work (CSCW). She has a background in linguistics, and incorporates social and communications theory in her work. She is a Scientist with the Social Computing group at the Qatar Computing Research Institute (QCRI). She works with the Crisis Computing team, and researches the use of social media sites and microblogging services during mass emergency events and humanitarian crises with the aim of creating methods and tools that enhance situational awareness in time- and safety-sensitive situations. In addition, Sarah studies the use of social media by Qatari adults, and looks at how they navigate cultural norms and identity through various online technologies. 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.
