Siobhan Leddy is a researcher, writer and artist exploring posthumanism in contemporary artistic practices. She is currently a postdoctoral researcher at Linköping University, where she is working on a Formas-EXPLORE-funded project, Eating the World. This explores the intersection of eating and artistic practices, through a feminist-posthumanist lens.

Previously, she was a postdoc at the Faculty of Fine Arts, Brno University of Technology (CZ), where she led Posthuman Voices, an artistic research project produced in collaboration with local artists. The project explores the materiality of voice as a more-than-human method for knowledge-creation. In this and other research projects, she aims to not only explore artistic practices as an object of study, but also asks how arts-based methods can lead us towards embodied and tacit knowledges, an approach that she always theoretically grounds in the feminist posthumanities. Her PhD was awarded by the Freie Universität Berlin (DE) in 2024, and explored the performativity of more-than-human sensoria in contemporary artistic practices.
