I am a Postdoctoral Health Statistics Research Fellow at the University of Exeter Medical School. I currently work on the following studies: 

Support for Parent Carers in England (SPaCE) - Investigating the prevalence of mental health conditions in parent carers of children with SEND using the Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES) data

Social Prescribing for people to live enjoyably with dementia/memory problems in daily life (SPLENDID) - Working on a complex intervention systematic review of social prescribing interventions in people living with dementia and/or their carers

In the future I would be interested in developing my skills further to include further work with routinely collected data such as Hospital Episode Statistics, SAIL or CPRD in order to establish relationships between comorbidities and/or personal characteristics and an individual patient's response to treatment.
