In this talk, I’ll present examples of Societal Computing work done by myself and interdisciplinary collaborators in the domain of international development and humanitarian response. Apart from highlighting advances in data innovation, I’ll describe real-world ethical challenges related to fairness, such as “leaving behind” the most vulnerable during crisis response, and risks of abuse, such as mapping undocumented migrants. I’ll close by outlining plans for an Interdisciplinary Institute for Societal Computing (IDISC) with the goal of strengthening research collaborations between computer science and both the social sciences and humanities.
