Large database epidemiology

I am a non-clinical epidemiologist at the University of Oxford, with a particular interest in database linkage, time course analysis, risk stratification, prognosis modelling and novel computational methods in epidemiology.

I work in EBM DataLab in Oxford, on the OpenPrescribing project, and am currently working on methods of change detection and developing composite prescribing measures amongst other things

Before coming to Oxford I was a Senior Research Fellow at The University of Nottingham, where I worked on a variety of projects relating to several disease areas, including; hepatitis C, cancer and venous thromboembolism. My work to date has mostly focused on using routinely collected data –data sources such as the CPRD, HES and ONS data– to answer pragmatic and clinically relevant questions. I completed my PhD in the Division of Epidemiology and Public Health at Nottingham, which involved pharmacoepidemiology, commonly prescribed drugs and cancer. Before that I completed a MSc in Oncology and a BSc in Biochemistry and Genetics.
