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.
