Maureen Kelley is Professor of Bioethics at the Ethox Centre and Wellcome Centre for Ethics & Humanities in the Nuffield Department of Population Health, University of Oxford, working in ethics and women’s and children’s health. Trained in moral philosophy, hospital-based clinical ethics, and qualitative methods, her work integrates empirical ethics within clinical and research practice to improve delivery of care and evidence-based advocacy for historically marginalised women, children, and young people. Dr. Kelley teaches across the medical and graduate programmes in Oxford Medical Sciences in medical ethics and international research ethics. Before joining Ethox in 2014, Dr. Kelley was on the faculty at the Treuman Katz Center for Pediatric Bioethics at the University of Washington and served as a clinical ethics consultant in paediatrics, paediatric palliative care, and for the child abuse and neglect team. She has worked closely with clinical researchers on projects for the Bill and Melinda Gates Foundation, NIH, H3 Africa, European Research Council, MRC, Wellcome Trust, and PATH, to identify practical solutions for ethical challenges in research and implementation projects in women’s health, maternal-child health and paediatrics. Projects have included: informing ethical guidance for paediatric HIV disclosure in children in Kenya; understanding the ethical barriers for inclusion of pregnant women in PrEP implementation studies in Kenya and Uganda; and addressing the ethical barriers for surveillance and parental support surrounding preterm birth and stillbirth in the global context. With collaborating investigators in South Africa, Kenya, Thailand and the UK she currently leads a Wellcome Trust sponsored research ethics study, REACH—Resilience, Empowerment & Advocacy in Women’s and Children’s Health Research. The empirical ethics project seeks to inform a deeper understanding of personal and institutional ethical obligations when working with vulnerable populations in global health research, including the role of research in responding to biomedical and social vulnerabilities.
