I work part time as a GP at the Windrush Medical Practice in Witney, West Oxfordshire.

My current areas of research interest are biomarker-guided asthma management and acute respiratory tract infections.

I am co-leading the NIHR-funded DEFINE programme, which aims to determine whether an online intervention which incorporates use of the fractional exhaled nitric oxide (FeNO) breath test can help reduce acute exacerbations of asthma in patients whose asthma is being actively managed in primary care.

I led the NIHR-funded ARCHIE trial, which evaluated the effectiveness of early antibiotic treatment in 'at risk' children with known risk factors for influenza-related complications during an influenza-like illness.   

I have also led two key studies in patients who present in primary care with persistent 'postinfectious' cough following an acute respiratory tract infection.  Firstly, a multi-centre clinical trial to find out whether montelukast, a medication which is already used to treat asthma, is also an effective treatment for postinfectious cough, and secondly, a study to work out how commonly we find whooping cough (pertussis) and Mycoplasma pneumoniae infections in children with postinfectious cough.  These findings will help inform evidence-based management of postinfectious cough as well as inform whooping cough immunisation policy in the UK.
