João Carlos Magalhães, Dr.
João Carlos Magalhães is a senior researcher at the Alexander von Humboldt Institute for Internet and Society, working in the Evolving Digital Society research programme. Previously, João researched and taught at the London School of Economics and Political Science, where he received a PhD in new media.
Much of his work explores the political and moral ramifications of algorithmic media and technologies. At the HIIG, he heads an EU-funded project that is mapping out social media platforms’ governance structures, with a focus on copyright policies and automated filters. In 2020, he was awarded a fellowship from the Wikimedia Foundation to help create an open database of platforms’ policies. His thesis, funded by an LSE Doctoral Scholarship, argued that Facebook’s AI-driven public space enables a form of bottom-up authoritarianism, in which citizens can only be heard by silencing themselves and others — what might demand a reconsideration of what an ‘ethical algorithm’ ought be. In 2021, he finished a project that looked into how Big Tech’s ‘AI for social good’ initiatives extend data colonialism.
He has also investigated the the use of microtargeting by political campaigns, the appropriation of the term ‘algorithm’ by ordinary people, the connections between media, recognition and ethics, and how the British press (mis)represented Jeremy Corbyn. Before becoming an academic, João worked as a journalist in Brazil, when he won some of the most important journalistic prizes in Latin America.
