Antonella Delmestri


Senior Health Data Scientist

  • CPRD fob holder
  • Big health data expert
  • Senior database manager

I am a computer scientist and software engineer at the Centre for Statistics in Medicine in NDORMS. I am in charge of the data management and advanced curation of big health data routinely collected from national datasets, e.g. the Clinical Practice Research Datalink (CPRD) GOLD and Aurum, the Hospital Episode Statistics (HES), the Office for National Statistics (ONS) Mortality, etc. 

My aim is to deliver high-quality advanced data curation for clinical statistics by developing robust and automated data processes regulated by Standard Operating Procedures. I am passionate about the impact that big data management can have in clinical research by contributing to performance, consistency, transparency and reproducibility of our deliverable results.


I graduated in Computer Science at Udine University and completed my PhD in Information and Communication Technologies at Trento University, Italy. I have worked for several years as analyst programmer and software engineer in companies developing firmware and software for electronic devices and became senior in that role.

In 2006 I moved to the U.K. to join the Clinical Trial Service Unit (CTSU) at Oxford University, and became part of the Early Breast Cancer Trialists' Collaborative Group (EBCTCG).  As Senior Analyst Programmer I was in charge of several Randomised Controlled Clinical Trials including the whole IT management of ATLAS (Adjuvant Tamoxifen Longer Against Shorter), a long-term study in breast cancer involving more than 15,000 women recruited from over 600 sites in more than 20 countries worldwide.

In 2013 I joined NDORMS as Database Manager to lead the data management of the Epidemiology Unit, whose main research interests focus on osteoarthritis, osteoporosis and fracture.
