Rachel Cassidy is an honorary Research Fellow in Health Systems Modelling. She is leading the systems thinking workstream on the COSMIC (Using Computer Modelling to Optimise the Design of Health System Programmes) Project. The work stream focus is on using systems thinking approaches (causal loop diagrams, system dynamics modelling) to further understanding on pathways to impact for results-based financing programmes and design recommendations for future implementation.

Rachel holds a MSc in Epidemiology and a MSc in Bioinformatics and Theoretical Systems Biology from Imperial College, London. Rachel successfully defended her PhD thesis in March 2023 at LSHTM. The thesis describes a body of work where Rachel used causal loop diagrams and system dynamics modelling to investigate health system strengthening in low-income settings, with aim to optimise the effect of interventions that target maternal and child health service delivery.
