Ioannis’ research work focusses on health issues affecting women and families living in resource-constrained settings, particularly targeting on ways to stop mothers dying from excessive bleeding during childbirth.

Every six minutes, a mother dies from losing too much blood while giving birth. The tragedy is that this is almost always preventable.

Oxytocin is the standard medicine for the prevention of bleeding, recommended for all women giving birth, but requires cold storage, which is unavailable in many countries. Ioannis led the evidence synthesis research at the University of Birmingham, which found that a heat-stable drug carbetocin is more effective, equally safe, and more cost-effective than oxytocin for preventing excessive bleeding after childbirth. Based on this work, the World Health Organization (WHO):

As a result, carbetocin has obtained regulatory approval and adoption of carbetocin into national guidelines and practice has begun in India, Kenya, and Nigeria.

Despite an effective prevention medicine, millions of women will still bleed excessively after childbirth. Women often go on to bleed excessively before the complication is recognised and treated.

Sparked by this global public health challenge, Ioannis is coordinating a global effort to tackle bleeding after childbirth, called the E-MOTIVE programme. The aim is to implement an early detection strategy and a ‘first response’ bundle of care for cutting down deaths and complications related to excessive bleeding by 25%. The E-MOTIVE team will work with international partners and coordinating centres in Kenya, Tanzania, Nigeria, South Africa, and Sri Lanka to test the E-MOTIVE intervention in a large randomised trial across 80 health facilities, involving over 300,000 women. The E-MOTIVE study is supported by the Institute of Global Innovation of the University of Birmingham and a $10.9M grant from the Bill & Melinda Gates Foundation.

For most women, if healthcare providers detect the problem early and treat it efficiently, the bleeding will stop and the mother will be safe. If, however, the treatment does not succeed and a woman continues to bleed despite the first response treatment, then her life is at risk. Ioannis is coordinating a team for developing, with funding from the Medical Research Council in the UK, a provisional management package for these women who continue to bleed despite first response treatment. This programme is due to be field-tested and piloted in five health facilities in Kenya.

Ioannis qualified M.D. cum laude from the University of Rome, Italy in 2005. During his undergraduate studies he received a number of travel research scholarships and distinctions.

He subsequently completed a Wellbeing of Women funded research training scholarship investigating the management and prognosis of endometrial hyperplasia, for which he has submitted his MD thesis and authored a Green top guideline on “The management of endometrial hyperplasia”. He then undertook a year of combined clinical training and academic work as academic clinical fellow in Oxford and John Radcliffe hospital before returning to University of Birmingham as a Clinical Lecturer and then as a sub-specialist trainee in Reproductive Medicine and Surgery. He started working as a Clinician Scientist in University of Birmingham and Honorary Consultant for Birmingham Women’s Hospital since February 2018. In July 2019, he was appointed as a senior lecturer in global women’s health and Joint Director for the WHO Collaborating Centre in Global Women’s Health at the University of Birmingham.


  •  MBChB course
  • 2nd year RED module

Postgraduate supervision

Currently, Ioannis is supervising eight PhD students. Has previously supervised students for BMedSc and electives and his students achieved outstanding success with publications in acclaimed academic journals such as the BMJ.


Evidence synthesis 

Ioannis has significant expertise in effectiveness and test accuracy data meta-analysis techniques, including advanced data synthesis approaches such as network meta-analysis, meta-regression and bivariate meta-analysis. He has been funded by the National Institute for Health Research and the World Health Organisation to carry out evidence synthesis that inform national and international guidelines.

Clinical trials

Ioannis is coordinating and is an investigator in several national and international trials.

Research groups and centres

Other activities

Ioannis is a consultant for the Tommy's National Centre for Miscarriage Research based at Birmingham Women’s Hospital. He runs a weekly clinic alongside Professor Arri Coomarasamy for couples that have suffered recurrent miscarriages.
