My research has predominantly focused on using observational data from the UK to address questions in cardiovascular disease prevention. My recently completed NIHR fellowship used EHRs from the UK (CPRD) and New Zealand (PREDICT) to understand how blood pressure lowering could be managed differently in England. As part of this work, we developed a Stata algorithm to calculate QRISK2 scores in CPRD. I have also worked on projects investigating statins for cardiovascular disease prevention, and alcohol recording in the CPRD. More recently I have worked in OpenSAFELY on a project examining mental health outcomes during the pandemic among people living alone, compared to those not living alone.

I am co-PI of the NIHR funded OpenPROMPT study - which is a novel study linking data collected from a mobile app to the EHR. This is a collaboration between epidemiologists and health economists at LSHTM, OpenSAFELY and GP software providers TPP.

I am also interested in pragmatic trials set within the electronic health record, and ways that we can use EHRs to support aspects of trials, for example for feasibility, recruitment and follow-up.
