Dr Jocelyn Friday

Lecturer in Data Science (Public Health)

Public Health, School of Health & Wellbeing, University of Glasgow, Clarice Pears Building, 90 Byres Road, G12 8TB

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 the use of large-scale electronic healthcare records from the University of Glasgow.

Jocelyn primarily uses R, Python, and SQL to analyse heterogeneous sources of structured healthcare data, including 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). In addition, she is a founding member of the Glasgow Lab for Health Data Science and AI (GLABDA).

Jocelyn is a member of the Network for Early Career Researcher Development (NERD), which aims to provide research staff and postgraduate researchers within the College of Medical, Veterinary & Life Sciences with career and professional development support while advocating for the needs of early-career academics. She is the chair of the Career Development, Fellowships, & Grants subcommittee, which hosts a range of events throughout the year, including career-focused workshops and discussion panels.

Research interests

Jocelyn's primary research focuses on health informatics, pharmacoepidemiology in heart failure, and cardiovascular epidemiology. Please see her GitHub for further information: https://github.com/jocelynfriday/.
