Personal profile

My research in Philosophy focused on understanding the importance of language in producing human dominion over animals. More concretely, I studied 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 investigated the role animal language can play in relation to the participation of animals in political decision-making processes and the construction of zoodemocratic systems.

Other research 

Research Assistant (RA) at the Cambridge Centre for Animal Rights Law (2021-2022, ongoing). As a RA, I provide advise on the development of an animal rights law text-book, specifically on the philosophical foundations of animal rights.

Visiting Fellow 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 fellow 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.
