Profile: I am a part-time PhD student at ScHARR, supervised by Dr Nick Latimer, Prof Matt Stevenson, and Prof Gianluca Baio (UCL). My research is focused on the use of external information to inform survival extrapolations based on clinical trials of cancer treatments. Outside of my PhD studies, I am a health economics analyst working in industry.

Qualifications

BSc Mathematics, Statistics and Operational Research, Cardiff University

MSc Health Economics and Decision Modelling, University of 91̽��

Research interests

My research interests are on the use of survival analysis methodology to estimate survival curves for use in healthcare decision making, specifically health technology assessments of cancer treatments. I am especially interested in estimating longer-term survival for treatments with novel mechanistic properties that are associated with complex hazard functions.

The working title of my PhD is ‘An exploration of methods to incorporate external information into survival modelling in oncology’.
