Biography

Jennifer Hollowell is a senior epidemiologist and Associate Professor in The National Perinatal Epidemiology Unit (NPEU). She has a PhD in Epidemiology/Health Services Research (St George’s Hospital Medical School, University of London), a first degree in mathematics (University of Oxford), and training in statistics and health economic evaluation.

Her research interests include maternal health/intrapartum care and inequalities in infant mortality. She was lead researcher for the Birthplace national prospective cohort study (see Birthplace webpage),which evaluated the safety of planned birth at home or in a midwifery unit, compared with planned birth in an obstetric unit. This landmark study of nearly 80,000 births has informed major changes to clinical guidelines for planned place of birth for women at low risk of complications. She is currently leading a follow-on programme of Birthplace related research. She is also involved in the Maternity and Women’s Health theme of the South London Collaboration for Leadership in Applied Health Research and Care (CLAHRC). Her research on inequalities in infant mortality is currently focusing on ethnic variations in infant mortality and other birth outcomes (see Infant mortality webpage).

In addition to academic research, Jennifer has worked as an epidemiologist and health economist in the pharmaceutical industry, and was Research Manager for the General Practice Research Database (GPRD, now CPRD) at the Office for National Statistics
