Personal profile


Picture of LigginsIn 2005, I completed my Ph.D. at the University of Sheffield, where my supervisors were Rosanna Keefe and Chris Hookway. Supported by an award from the Analysis Trust, I spent the 2005-6 academic year at the Faculty of Philosophy at Cambridge, continuing my research. I became a Lecturer at Manchester in 2006, and a Senior Lecturer in 2010.

I spent the 2009-10 academic year on research leave, thanks to an AHRC Research Leave award.

From 2011 to 2014, Chris Daly and I directed a research project entitled The Foundations of Ontology, funded by the AHRC.

I was an Associate Editor of the Australasian Journal of Philosophy from 2009 to 2016. From September 2021, Stacie Friend, Lee Walters, and I are the Editors of Analysis.

Research interests

The philosophy of mathematics was the subject of my Ph.D. thesis and remains a major research interest of mine. In particular, I have defended nominalist accounts of mathematics: those which do not posit mathematical objects such as numbers or sets. Other ontological debates also interest me, particularly those concerning possible worlds, composite objects, and propositions. I have tended to explore theories which posit less rather than more, which has led me to think about paraphrase, pretence, fictionalism, and error theory. At present I am working on a book which brings some of these ideas into discussions of truth and paradox.

Other interests include philosophical method, grounding, and metaontology.
