Personal profile

I am a PhD candidate at the School of Humanities, Royal Holloway (University of London). My thesis in Philosophy focuses on understanding the importance of human language in producing human dominion over animals. More concretely, I study the influence language has in framing humans' perception of animals in spaces such as factory farms, and the way language shapes the ethics and politics of animal law and ethology. 

My research also investigates a dimension of language that, I contends, is shared between humans and animals. My argument is that non-human animals can participate in political decision-making processes because they have this shared language, which leads me to explore the role these philosophical insights can play in building zoodemocratic systems.

Other research 

Visiting Researcher at St. Edmund's College, University of Cambridge, and at the Cambridge Centre for Animal Rights Law (2020-2021). Research project: Legal Animalhood: The Constitutional Recognition of Wild Animals in Australia (see lecture here)

As a researcher at Cambridge, I studied how the Constitution of the Commonwealth of Australia should change in light of the argument advanced by Sue Donaldson and Will Kymlicka that wild animals should have a right to self-determination.
