Yuze Sha is a discourse and communication researcher. Her research sits at the intersection of public health communication, digital media, and multimodal meaning-making. She examines how legitimacy and trust are produced, negotiated and challenged through semiotic resources and platform affordances, particularly in public health discussions.

Yuze’s recent work includes analyses of NHS COVID-19 policy communication on Twitter/X and public responses to those messages, anti-vaccination discourse across pseudoscience and conspiracy websites, and public and media representations of perpetrators and victims in violent crime. Methodologically, she is interested in innovations in multimodal and corpus-based approaches to discourse studies, with particular attention to linking scalable pattern analysis with qualitative, context-sensitive interpretation.

Yuze is working on the Wellcome-funded project “Between Deception and Dissent”, which studies how unproven, disproven, or misleading health claims are regulated in contemporary states, and the socio-political consequences of current approaches.
