Siobhan Leddy is a researcher, writer and artist exploring posthumanism in contemporary artistic practices. She is currently a postdoctoral researcher at the Faculty of Fine Arts, Brno University of Technology (CZ), where she is project lead of 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.

In addition to publishing work in both academic and popular science contexts, she has also recently acted as guest editor (2023-2024) of the tenth-anniversary issue of the cross-disciplinary journal PULSE: The Journal of Science and Culture. In her own artistic practice, she adopts an interdisciplinary and multispecies approach, with work exhibited at Floating University (Berlin), Het Nieuw Institut (NL), Cashmere Radio (DE), Oberhausen Short Film Festival (DE) and others.
