Jennifer is an Honorary Clinical Lecturer at Birmingham Women’s & Children’s Hospital. Funded by a Wellbeing of Women Clinical Research Fellowship, Jennifer utilised her PhD to explore vitamin D metabolism in pregnancy, and the potential effects of vitamin D upon immune cell function within the maternal placenta at the University of Birmingham. To help answer these questions Jennifer utilised a range of novel experimental techniques, including mass spectrometry-based steroid analysis, RNA-sequence analysis, bio-informatic pathway analysis and mathematical modelling. Her central research interests are fetal implantation, early placentation and immune cell function at the materno-fetal interface. Understanding how these processes become dysregulated in women with recurrent failed implantation and aberrant placentation disorders such as recurrent pregnancy loss, subfertility and pre-eclampsia shall help guide future preventative and therapeutic strategies.


  • Clinical Lecturer in Obstetrics and Gynaecology
  •  PhD Research Clin Ex Med (2018)
  • MRCOG Part 1 (2013)
  • MBChB (2011)
  • BMedSci (2009)


Having successfully attained a Wellbeing of Women Research Training Fellowship Jennifer completed her PhD at the Institute of Metabolism and Systems Research generating unique data on steroid metabolism and immune cell function across human pregnancy. Of particular interest was the transcriptomic response of uterine natural killer cells to vitamin D and immune challenge.

As a Clinical Lecturer in Obstetrics and Gynaecology Jennifer is now working between the University of Birmingham and Birmingham Women’s & Children’s Hospital Foundation Trust. Her main research interests surround early implantation, decidualisation and immune cell function at the materno-fetal interface. As research lead for the CHHIP study, Jennifer’s work has maintained a strong translational focus, studying women at high risk of disorders of malplacentation, in particular pre-eclampsia. Moving forward, Jennifer’s hopes her work shall contribute to the Tommy’s pioneering programme of work upon the prevention of recurrent miscarriage and development of potential future therapeutic strategies.

Jennifer is also Academic Lead for the UK Audit and Research Collaborative in Obstetrics and Gynaecology (UKARCOG; 2015) which has established a National trainee network to promote women's health research and deliver high-quality impactful national research projects.
