With an on-campus student exhibit, an online platform and in partnership with a Tunisia-based migrant advocacy organization, this study seeks to facilitate space for the stories of families of missing migrants of the Mediterranean, whose voices are often absent in dominant narratives. This research explores how families navigate that space that toggles between loss and hope, and what it means to pursue advocacy, as they seek to be heard. Our interdisciplinary, transnational team, comprised of faculty, students and practitioners, aims to bring social justice and advocacy together with design and technology into a powerful and meaningful synthesis in public scholarship.
