Professor of Ethics, Keele University

My research engages with issues in applied ethics, especially bioethics, from a philosophical perspective; often linking issues in metaphysics with problems of ethics. My major research topics include questions on the margins of life (reproductive and end of life ethics), personhood, concepts in bioethics (the nature of disease, illness and vulnerability), moral authority and autonomy, extended decision-making, and the nature of expertise in ethics. I also engage in the critical ethical evaluation of legislation and policy on matters of biomedical and research ethics.

My work divides into three main areas:

Biomedical Ethics and Research Ethics:
End of life ethics, reproductive ethics, concepts in bioethics, and the nature of bioethics.

Ethics and Policy/Law:
Ethical appraisals of legislation and policy governing medicine in areas such as advance directives/proxy decision-making, mental health, and end of life care.

Metaphysics, philosophical and applied:
Realism and anti-realism debates; conceptual analysis.
