Jonathan Corpus Ong is an associate professor of global digital media at the University of Massachusetts Amherst. The central concern of his work is the ethics of media, which he approaches as the moral and social consequences of media and communication technologies in the everyday lives of minority groups and vulnerable communities, especially those in the global South. His research develops an ethnographic and decolonial approach that sensitively embeds media practice within rich local histories and ordinary motivations while engaging with normative debates about media justice and cosmopolitan ethics in complex multicultural societies. He has published extensively in the areas of global media; disasters, development and humanitarian communication; ethnography of social media; creative and digital labor; mediated protest, witnessing and solidarities; and ethics of communication. He has supervised Ph.D. students working in the areas of media in everyday life among Nigerian migrants in London, digital protest in class-divided Thailand, and Belgian audiences of distant suffering. He is the founder and convenor of the British Council-funded Newton Tech4Dev Network, which is a global network of academics, humanitarians, and technology experts studying emergent media in low- and middle-income countries.
