At the Communication Media and Marginalization Lab (CoMM Lab) at the Network Science Institute at Northeastern University, we examine the relationship between marginalization and communication technology. Using theories of communication power and media control, network and computational social science methods, and data from online and traditional media sources, we aim to understand how and why marginalization happens. From social media to businesses to schools and more, we aim to identify - and disrupt - the explicit and implicit processes that prevent some people and ideas from being fully heard.
