Personal profile


Mianna joined the Department of Philosophy at Macquarie in 2005 as Associate Lecturer in Ethics/Applied Ethics. Prior to her arrival she was a Research Fellow at the Centre for Applied Philosophy and Public Ethics, University of Melbourne, and a Lecturer at La Trobe University. Mianna holds a PhD from Monash University, and since graduating has taught subjects in normative and meta-ethics, applied and professional ethics, and social philosophy at a number of universities in Australia and New Zealand.

Research interests

Mianna's primary current research interests are in the ethical and political philosophy of the family, childhood, parenting and reproduction, including recent biotechnological and surgical innovations, with a particular focus on questions pertaining to parental obligations/liberties and children's autonomy, rights and welfare.

She is currently working on an international collaborative project on the ethics of uterus transplantation, called 'Ethics of Uterus Transplant in Australia: Lessons from Sweden and the UK'.

Mianna is a member of the international Research Network on Democracy, Ethics and Public Policy (DEPP). See here: http://demographyethicsandpublicpolicy.weebly.com/

She is part of an international project team working on the ethics and political philosophy of procreation and education (http://www.phil.ufl.edu/events/2015/02/pepr/index.html) and was an international co-applicant on a broad, interdisciplinary, collaborative project in the humanities and social sciences, called "What Sorts of People Should There Be?" a project exploring historical, social and ethical issues in biotechnology, enhancement and eugenics.
