Professor Arri Coomarasamy is a distinguished academic and clinician at the University of Oxford, serving as Professor of Gynaecology and Reproductive Medicine and Director of Tommy's National Centre for Miscarriage Research. He is also an Honorary Consultant Gynaecologist at John Radcliffe Hospital. His work spans the Nuffield Department of Women's and Reproductive Health within Oxford's Medical Sciences Division, where he leads groundbreaking research in women's reproductive health. Professor Coomarasamy received his undergraduate medical education from the University of Birmingham and completed subspecialist training in reproductive medicine and surgery at Guy's Hospital, London. His academic journey has positioned him as a leading authority in reproductive medicine with significant contributions to clinical practice and research methodology. His research interests focus primarily on miscarriage prevention and global women's health, with particular emphasis on understanding why one in four pregnancies end in miscarriage and developing interventions to prevent maternal deaths during childbirth. His work encompasses reproductive immunology, investigating the role of immune cells like natural killer cells and regulatory T cells in pregnancy maintenance. He has pioneered research on treatments to prevent miscarriages and interventions to stop mothers dying from postpartum hemorrhage, which claims a mother's life every two minutes worldwide. Professor Coomarasamy's publications reveal a strong focus on clinical trials methodology, evidence synthesis, and implementation science, particularly in resource-limited settings. His work bridges basic science discoveries with practical clinical applications, with a special emphasis on translating research findings into global health policy and practice. OBE (Order of the British Empire) Professor Coomarasamy serves on numerous international and national committees including grant funding boards for NIHR, MRC, Wellcome and DfID, the BJOG editorial board, the RCOG Wellbeing of Women Research Panel, various WHO committees, and multiple clinical studies groups. He is the founding trustee of Ammalife, a UK-registered charity dedicated to reducing maternal deaths in low-income countries. His mentorship has cultivated a generation of outstanding clinicians and researchers in reproductive medicine. He leads two major research teams: one focused on treatments to prevent miscarriages and another targeting ways to prevent maternal deaths during childbirth. His laboratory work investigates immune cells in the endometrium of patients with recurrent miscarriage, while his clinical work spans multiple international trials addressing critical gaps in women's reproductive healthcare globally.
