About Siobhan O'Sullivan

Lived 1974 – 2023 (aged 49). Siobhan O'Sullivan was an Australian political scientist and research fellow.

Siobhan O'Sullivan (19 March 1974 – 17 June 2023) was an Australian political scientist and political theorist. She was an associate professor in the School of Social Sciences, University of New South Wales. Her research focused, among other things, on animal welfare policy and the welfare state. She was the author of Animals, Equality and Democracy (2011, Palgrave Macmillan) and a coauthor of Getting Welfare to Work (2015, Oxford University Press) and Buying and Selling the Poor (2022, Sydney University Press). She co-edited Contracting-out Welfare Services (2015, Wiley) and The Political Turn in Animal Ethics (2016, Rowman & Littlefield International). She was the founding host of the regular animal studies podcast Knowing Animals, as well as a founder of the Australasian Animal Studies Association.

Life and career Siobhan O'Sullivan read for a PhD in government and international relations in the Faculty of Economics and Business, University of Sydney, where she was supervised by Lyn Carson. Her thesis, entitled Animal Visibility and Equality in Liberal Democratic States: A Study Into Animal Ethics and the Nature of Bias in Animal Protection Regulation, was submitted in May 2007. It was examined by Denise Russell and Robert Garner. O'Sullivan graduated in 2008. In that same year, she became a research fellow at the School of Social and Political Sciences at the University of Melbourne, spending some time at Clark University, Massachusetts, as a part of the Human-Animal Studies Fellowship program.

O'Sullivan was based at the University of Melbourne for seven years, and subsequently became a lecturer in social policy in the School of Social Sciences, University of New South Wales. In 2015, her Getting Welfare to Work: Street Level Governance in Australia, the UK and the Netherlands (coauthored with Mark Considine, Jenny M. Lewis and Els Sol) was published with Oxford University Press, and the edited collection Contracting-out Welfare Services: Comparing National Policy Designs for Unemployment Assistance, edited by O'Sullivan and Considine, was published with Wiley. Another collection, The Political Turn in Animal Ethics, co-edited by O'Sullivan and Robert Garner, was published by Rowman & Littlefield in 2016.

In August 2020, O'Sullivan was diagnosed with ovarian cancer. She became a spokesperson for the Ovarian Cancer Research Foundation and established animal studies prizes with the Australasian Animal Studies Association, In 2022, she published Buying and Selling the Poor, co-authored with Michael McGann and Mark Considine, with Sydney University Press. While living with cancer, O'Sullivan publicly campaigned for the legalisation of assisted dying in New South Wales; Alex Greenwich's Voluntary Assisted Dying Bill 2021 was passed in May 2022.

Research On the website of the University of New South Wales, O'Sullivan was listed as conducting research into "the delivery of contracted employment services in Australia, the UK, and around the world".

O'Sullivan was a key figure in the "political turn" in animal ethics (i.e., the emergence of animal ethics informed by political theory rather than moral philosophy). In her Animals, Equality and Democracy, O'Sullivan explored the issue of the unequal treatment of members of different species in contemporary societies. However, she drew a distinction between the "external inconsistency" and the "internal inconsistency", with the former being the inconsistency between the treatment of humans and other animals, and the latter being the inconsistency between the treatment of different nonhuman animals. While traditional analyses of the issue have focused on the external inconsistency, O'Sullivan looks to the internal inconsistency. In particular, O'Sullivan argued that those animals who are more visible are offered greater protection under the law. So, for example, while animals used in agriculture are shielded from public view, animals used in sport have relatively high levels of public visibility. She proposed a new approach to animal advocacy, suggesting that advocates focus on the internal inconsistency rather than the external inconsistency.
