Dr. Jianni Tien is an interdisciplinary scholar working at the intersection of the environmental humanities, feminist theory and science and technology studies (STS), with a disciplinary background in media and communications. She is interested in the porous boundaries and material entanglements between the human and non-human; the environment, and larger systems of epistemological power.

Jianni researches a range of topics including the ontologies of hydrogeologic structures such as limestone sinkholes, human-microbial relations, and the materialities of pollution, toxicity and waste in the Anthropocene. She brings overlapping conceptual lenses to these topics, including non-representational theory, material feminisms, new materialism, hydrofeminism and geophilosophy. Methodologically Jianni is interested in experimental feminist forms of knowledge-creation, including bodily methodologies and practice-led research.

Jianni works as a Postdoctoral Research Fellow in the Sydney Centre for Healthy Societies at the University of Sydney, where she co-leads the ‘Embodying the Anthropocene’ research theme. She is currently writing a book on scuba diving as a bodily method of engagement with cenotes (naturally occurring subterranean reservoirs of water) – and how such experimental approaches to the “hydro” and the “geo’ may allow for more just responses to the Anthropocene.
