Morgan Wack

I am a Postdoctoral Scholar in the University of Zurich's Department of Communication & Media Research (IKMZ). My research is focused on understanding how digital technologies are used to influence the public. This includes research into novel forms of disinformation and the use of LLMs to develop propaganda, as well as work developing interventions to mitigate their impact.

Previously, I was a Research Assistant Professor at Clemson University's Media Forensics Hub. I received my PhD from the University of Washington. I am the consulting scientist for the International Panel on the Information Environment (IPIE)'s Indexing Panel, an affiliate of the Center for Information, Technology, and Public Life (CITAP), and a member of both the Coalition for Independent Technology Research (CITR) and DSI Digital Publics communities.
