Simon is a postgraduate research student on a National Institute for Health Research (NIHR) Birmingham Biomedical Research Centre (BRC) funded PhD. He is a member of the University of Birmingham Test Evaluation Research Group (TERG) and Biostatistics, Evidence Synthesis and Test Evaluation (BESaTE) group, and an honorary contract holder at University Hospitals Birmingham in the Health Informatics Research group.


  • BA (Hons) in Mathematics and Music, University of Birmingham, 2015


Simon studied Mathematics and Music at the University of Birmingham. Prior to starting his PhD, Simon worked at University Hospitals Birmingham in a collaborative role with the European Association for Cardio-Thoracic Surgery (EACTS) chaired by Professor Domenico Pagano, providing technical and statistical support to Quality Improvement Programmes (QUIPs). Simon was also a member of a joint Cancer and Genomics-Health Informatics Research group chaired by Mr Prashant Patel, providing statistical support to projects, several of which have now been published.


Doctoral research

PhD title
'Opportunities and Challenges in Using Routine Data Sources to Evaluate Biomarkers' Expected year of completion: 2022 Third Supervisor Dr Alice Sitch
Professor Jon Deeks and Professor Yemisi Takwoingi


Simon’s PhD research is on methods to estimate and evaluate components of variability from pre-existing datasets containing repeated biomarker measurements taken on subjects over time, such as in clinical trial and routine data sources. Unlike when conducting prospective longitudinal Biological Variability Studies (BVS), pre-existing datasets rarely contain the necessary data required for methods commonly used in longitudinal BVS. Methods that address the limitations of using pre-existing datasets have important implications to investigating how components of variability can be estimated and evaluated retrospectively.
