Maureen is Associate Professor of Bioethics at The Ethox Centre and Wellcome Centre for Ethics & Humanities in the Nuffield Department of Population Health at the University of Oxford. Her research aims to identify, describe in depth and address practical ethical challenges arising in care and research in women’s and children’s health, with a focus on women and children living in contexts of poverty, political conflict, or gender discrimination. She is currently leading a collaborative research ethics project with partners in Thailand, South Africa, and Kenya, supported by the Wellcome Trust. The REACH study – resilience, empowerment, and advocacy in women’s and children’s health research – prospectively engages teams of researchers and participants over time to better understand the ethical challenges that arise in global health research in contexts of systemic social, economic and political vulnerability, and how research teams respond to participant, family and community needs through research, engagement and advocacy. Findings will inform research priority setting, study design, researcher training and support, and research ethics governance in global health.
