Professor Shakila Thangaratinam is Dame Hilda Lloyd Chair of Maternal and Perinatal Health at the University of Birmingham, and leads the Maternal and Reproductive Health Theme (Jan 2020-). She is the co-Director of WHO Collaborating Centre for Global Women’s Health and academic lead for Women’s Health in Birmingham Health Partners. As Consultant Obstetrician she is involved in the care of high-risk mothers at Birmingham Women’s and Children’s NHS Foundation Trust.

In her previous role as Professor at Queen Mary University of London (2012-2019), Professor Thangaratinam established the Barts Research Centre for Women’s Health (BARC). She established Katie’s Team, a dedicated Patient and Public Involvement group in East London, whose members contribute to NIHR Boards and studies. More recently, she established the Dame Hilda Lloyd Network, which brings together medical and midwifery students and trainees, school students, and senior clinical academics involved in Women’s Health Research in the West Midlands.

To ensure that the views of women in the West Midlands are captured within Professor Thangaratinam’s research at Birmingham, she has established a second Patient and Public Involvement Group named The Hildas. The women in this group are consulted on current research ideas which enables the groups' research to be collaborative.

Professor Thangaratinam’s work focuses on prediction, prevention and treatment of complications in mothers with pre-eclampsia, epilepsy, diabetes, and obesity. She leads large global collaborative networks such as the NIHR-funded International Weight Management in Pregnancy (i-WIP) collaborative group (40 researchers, 16 countries, >50,000 women), with the largest live repository of individual data and the IPPIC (International Prediction of Complications in Pregnancy) collaborative network (73 collaborators, 21 countries, >5 million pregnancies). She has accrued research income of over £12 million, and published in first or last author position in Lancet (2019, 2015, 2012), BMJ (2022, 2021, 2020, 2017, 2016, 2012, 2011), Lancet Global Health (2017), Lancet Haematology (2021), and multiple HTA monographs. Prof Thangaratinam was awarded the NIHR Senior Investigator Award in March 2021.

Professor Thangaratinam started her research career as a Clinical Research Fellow at Keele University in 2004, and subsequently joined University of Birmingham in 2006 as a Clinical Lecturer in Obstetrics and Gynaecology. In 2011, she was awarded a PhD in ‘Health Technology Assessments in Maternal and Perinatal Health’.

After the completion of her clinical and academic training, she was appointed by Queen Mary University of London (QMUL) to the post of Clinical Senior Lecturer in 2011, and was a full professor at QMUL between 2012-2019. She established the research support network, Katherine Twining Network (9 NHS hospitals, 3 Universities) in North and East London to deliver women’s health research, and Katie’s Team, the only dedicated and funded Patient and Public Involvement group for Women’s Health in the UK. As R and D Director for Women’s Health at Barts Health NHS Trust until 2019, she was instrumental in integrating research within everyday clinical practice. She was the joint Director of Barts Research Centre for Women’s Health (BARC) and undertook cutting-edge research on the problems facing women and children in East London.

She currently leads a portfolio of work in Women’s Health in areas such metabolic disorders in pregnancy (obesity, gestational diabetes), epilepsy, pre-eclampsia, stillbirth, fetal growth, and preterm birth. She co-leads the WHO Collaborating Centre for Women’s Health at University of Birmingham.


She completed her Advanced Training in Specialist Medicine (ATSM) modules in maternal medicine, labour ward management and medical education, and completed her Core Training (CCT) in obstetrics and gynaecology in August 2010 at the Birmingham Women’s Hospital, the largest and busiest tertiary obstetric unit in West Midlands. Her academic work complemented her interest in maternal medicine with projects in pre eclampsia and epilepsy.

She is an Honorary Consultant at Birmingham Women’s and Children’s NHS Foundation Trust.


Research support for full time clinicians

Under Professor Thangaratinam’s supervision, 10 clinical trainees and 6 NHS Consultants in obstetrics, obstetric anaesthesia, dietetics, endocrinology, neurology and neonatology departments in Barts Health published papers during their time with her.

She helped to improve the evidence based skills of clinicians through the Critical Appraisal of a Topic (CAT) journal club sessions. Here are some of the results of the evaluation of the CAT club: 88.9% stated CAT definitely improved their critical appraisal skills; 77.8% stated they would definitely recommend CAT club to a friend or colleague. The CAT training was used 54.5% of the time for direct patient care and teaching and presenting, and 36.4% changed patient care in choice of drugs or other treatments.

She engages undergraduate students in research and offers research governance training. Over 10 students have recruited in trials, and co-authored 5 papers.

She has experience of being the lead for NIHR academic trainee appointment in Women’s Health

Research areas of interest

Metabolic disorders: Obesity, diabetes and polycystic ovary syndrome

Evidence synthesis through NIHR and WHO funded aggregate and Individual Participant Data (IPD) meta-analysis to determine the effects of diet and physical activity in pregnancy. Shakila led the ESTEEM study, the largest randomised trial on Mediterranean diet in pregnancy to prevent maternal and offspring complications. She is currently leading three pilot/feasibility studies funded by Barts Charity and North Thames Collaborations for Leadership in Applied Health Research (CLAHRC): EMmY trial on the effects of myo-inositol to prevent gestational diabetes; prevention of progression to type 2 diabetes in mothers with gestational diabetes with metformin: Optimising health outcomes by using metformin to reduce risk of diabetes after pregnancy (OMAhA); and with Mediterranean diet for prevention of progression to type 2 diabetes in women with gestational diabetes (MERIT).

Maternal and perinatal medicine: Pre-eclampsia, epilepsy, stillbirth, fetal growth, infection

She leads the International Prediction of Complications in Pregnancy (IPPIC) IPD meta-analysis project funded by NIHR HTA and supported by the WHO. The IPPIC collaborative network consists of 73 collaborators from 21 countries, and is the largest global repository of standardised IPD of over three million pregnancies (15 UK, 66 international datasets). She led the Prediction of complications in women with pre-eclampsia (PREP) study funded by NIHR HTA which led to the development of an app that is accurate to predict complications. She led the NIHR HTA funded EMPiRE trial, the first randomised trial involving women with epilepsy. Her work on risk of stillbirth in twin pregnancies (BMJ 2016) garnered significant media attention.

Global Health: Caesarean section, anaemia

Assessment of the safety of caesarean section in Low and Middle Income Countries (LMIC) through large meta-analyses on risks associated with anaesthesia (Lancet Global Health 2016) and the burden of maternal death following caesarean section in LMIC (Lancet 2019). The focus on the effective prevention of anaemia in pregnancy and its complications in women and children with iron fish and also with use of intravenous iron.

Other activities

As member of National Institute for Health Research (NIHR) for Patient Benefit (RfPB) Board for London, Professor Thangaratinam plays a crucial role in peer review and decisions on funding for portfolio studies.

She is on the Academic Board of the Royal College of Obstetricians and Gynaecologists (RCOG) as a HEI (Higher Education Institution) representative, and developed the annual RCOG academic training course that is mandatory for trainees taking the Advanced Professional Module (APM) module.

As an executive committee member of the RCOG Maternal Medicine CSG (Clinical Study Group) she is involved in the prioritisation of research questions.

She led the development of the national RCOG Greentop guideline on epilepsy in pregnancy. As a member of the UK Chief Medical Officers’ infographic development group on physical activity in pregnancy, she was involved in making UK wide recommendations. She provided expert input into the UK Government review led by Baroness Cumberledge on the effects of sodium valproate on congenital abnormalities in offspring born to women with epilepsy.

As a member of the International guideline committee on treatment of infertility in women with polycystic ovary syndrome, in addition to making recommendations, she identified gaps to inform future research, including the promising role of myo-inositol for ovulation induction in these women.

She chairs the trial steering committees of multicentre trials LOTUS, PREVIEW, SOLVE and Alife 2, which are national and international NIHR funded studies.

Her evidence synthesis on association of complications in women with epilepsy (Lancet 2015) directly informed RCOG Green Top guidelines on the management of pregnant women. Professor Thangaratinam's work on risk of stillbirth in twin pregnancies (BMJ 2016) informs the national guidelines and garnered significant media attention.
