Biography
Sian completed her PhD in Clinical Psychology in 2002 and worked as a Clinical Psychologist before joining the University of Oxford in 2009.
Sian worked in the Nuffield Department of Primary Care Health Sciences between 2009 and 2015 where she coordinated two large surveys in cancer care and cardiovascular disease. She also coordinated OxWATCH, a cohort feasibility study to explore the impact of pregnancy on women's health and wellbeing. Whilst working for the Centre for Evidence Based Medicine, Sian was involved in the development of WHO guidelines for self-care in non-communicable disease.
Sian joined the National Perinatal Epidemiology Unit (NPEU) within the Nuffield Department of Population Health in 2016. She is part of the NIHR Policy Research Unit in Maternal and Neonatal Health and Care (PRU-MNHC). Sian is currently working on the National Maternity Surveys, which are large population-based surveys of maternal and infant health, carried out at regular intervals by the NPEU.
Sian's research interests are in perinatal mental health.
