Since joining the School in 2007 I have been working in electronic health record research.   


Faculty of Epidemiology and Population Health
Department of Non-communicable Disease Epidemiology


My teaching commitments are currently a combination of in-house and distance learning modules.  In-house, this includes facilitating group practical sessions for Extended Epidemiology.  For distance learning, I teach on EPM103 (Practical Epidemiology) and EPM202 (Statistical Methods for Epidemiology).  

I have previously taught on Statistics for Epidemiology and Population Health (STEPH), Advanced Statistical Methods in Epidemiology, the Intensive Short Course in Epidemiology and Medical Statistics, Basic Maths and the PASS scheme for MSc students struggling with Extended Epidemiology and STEPH. 

I am currently a co-Module Organiser for EPM103 Practical Epidemiology.


My role as an Assistant Professor involves utilising electronic health records for observational and interventional research. 

In the observational stream of my work, I use the Clinical Practice Research Datalink, Hospital Episode Statistics and the Myocardial Ischaemia National Audit Project to carry out studies investigating cardiovascular disease and its prevention.  

I have been awarded a NIHR Post Doctoral Fellowship to investigate the way that we manage blood pressure in the UK.  I will use records from general practice in the UK and New Zealand to explore whether it would be best to use blood pressure thresholds or absolute cardiovascular disease risk to guide blood pressure lowering treatment.

In the interventional stream of my work, I recently completed a cluster randomised trial in 156 UK primary care practices, which investigated the effectiveness of a text message influenza vaccine reminder on vaccine uptake in at-risk groups under 65.  I am involved in the StatinWISE trial, which investigates whether statins cause muscle symptoms.  I am also interested in the use of electronic health records in randomised trials.
