Dr Rees is an NIHR Doctoral Fellow and paediatrician with an interest in improving population child health through leveraging routine data to inform policy and practice. As part of her NIHR award Dr Rees leads the CHERuB study (NIHR 301457). The CHERuB study will harness and link several national datasets to establish a population matched cohort study, enabling the exploration of long-term health and educational outcomes of children after perinatal brain injury.

Dr Rees' interest in clinical academia first arose during her intercalated Epidemiology BSc, on realising the potential for research to influence the health of a whole population. This led to her undertaking an MPhil exploring paediatric care quality using a mixed-methods approach with a large national dataset. In parallel, she contributed to a wider NIHR-funded study of primary care safety (HS&DR 12/64/118). Dr Rees' role included leading the paediatric workstream and developing novel methods to analyse safety data.  The methods and coding taxonomy developed during this project are now used internationally by researchers and are considered a significant methodological advance in the field. As such, Dr Rees holds an honorary clinical lectureship at Cardiff University where she leads the team’s paediatric agenda on value-based healthcare, supervises BSc students, lectures, and writes grants.
