Biography

Jocelyn Friday graduated from the University of St Andrews with a BSc (Hons) in Computer Science and Mathematics. Subsequently, she completed an MSc in Bioinformatics from the University of Edinburgh and then a PhD in Cardiovascular Science, focusing on using large-scale electronic healthcare records from the University of Glasgow.

Jocelyn primarily uses R, Python, and SQL to aid in analysing heterogeneous sources of structured healthcare data from death, community-dispensed prescribing, primary care, hospitalisation, biochemistry and haematology, echocardiographic, and electrocardiographic records from sources such as West of Scotland Safe Haven and Clinical Practice Research Datalink (CPRD).
