Clinical Data Lead

Professional Services role

As the Clinical Data Lead within the Ludwig Institute I act as a link between data collection in local NHS hospitals and data usage for research within the University. I particularly work with the clinical teams involved in oesophageal and gastric cancer care, and with Ludwig-based researchers who have an interest in these tumour types.

My role involves designing and developing databases, extracting and analysing data from patient health records, and providing researchers with pertinent information about a patient’s cancer treatment to aid the interpretation of analyses carried out on donated blood and tumour samples.


As a member of Oxford Cancer, I head the Clinical Data team, overseeing the research data aspects of the Suspected CANcer (SCAN) Diagnostic Pathway and helping to set up and run research data collection for new projects.


Before joining the Ludwig in 2016, I spent four and a half years as a Data Manager in the Nuffield Department of Obstetrics and Gynaecology, where I coordinated all aspects of data collection, entry and quality control for the INTERBIO-21st Study and the INTERGROWTH-21st Project across 12 research sites around the world.

I hold a BSc in Statistics (First Class Honours) from the University of Bath and have also previously worked in the Statistical Enquiries Service for NHS Blood and Transplant, and as an Information Analyst for psychology services at the Maudsley Hospital in South London.
