I am passionate about data. During my PhD (2010-2013) funded by Kidney Research UK using data from and collaborating with the UK Renal Registry I was able for the first time to link registry data to Hospital Episode Statistics data to undertake a range of analyses. This research is used as a case study by NHS Digital, the Association of Medical Research Charities and Understanding Patient Data to highlight the value of secondary data analysis and data linkage.
I have received national junior investigator awards from the British Transplant Society and the Renal Association for analyses arising from this project. In 2015 was received an NIHR Clinician Scientist Award to fund my continued research into the excess admissions and deaths associated with the two-day break in patients receiving three times a week haemodialysis. This award allows me to continue clinical practice as a consultant nephrologist at the Sheffield Kidney Institute.
I am involved in a number of other renal studies including the UK-Catheter study (an ancillary study to the Peritoneal Dialysis Outcomes and Practice Patterns Study) and SHARE-HD, a study designed to promote and understand the impact of encouraging in-centre haemodialysis patients to perform more tasks relating to their dialysis treatment. Collaborating with others I have published on albuminuria, obesity and renal bone disease, often championing the use of existing trial and cohort study datasets.
Outside of kidney disease, was part of the group who undertook the statistical appraisal of Summary Hospital Mortality Indicator for the Department of Health/NHS Information Centre, and have supervised the analysis a range of cohorts to understand the impact of smoking on cardiovascular events the prognosis following them. I coordinate and deliver medical education for medical students and core medical trainees.
