His research is focused on integrating theoretical, empirical, and design-based investigations of computing systems and artefacts in support of community and civic engagemen. He directs the Participatory Publics Lab—PPL—where students and community members develop participatory design approaches to co-creating mobile and digital media. From richly interactive and data-driven websites, to interactive installations exploring oral history and community narratives, to mobile apps that contribute to smarter cities, PPL researchers are pursuing new forms of civic participation.
