Dr Louise Fleming completed her undergraduate degree in medicine at the University of Manchester before moving to London for postgraduate training in Paediatrics. This included an 18-month VSO/RCPCH Fellowship in The Gambia.

She carried out a randomised controlled trial investigating the use of inflammatory markers to guide management in children with severe asthma.

Dr Fleming’s research interests include characterizing problematic severe asthma; monitoring asthma including adherence and use of biomarkers; identification of novel therapeutic targets and non-pharmacological management of asthma including behaviour change. Current work includes the use of novel adherence monitoring devices, understanding determinants of poor adherence in the individual and targeting interventions accordingly. Clinically she looks after children with a wide range of respiratory problems. Interests include the systematic multi-disciplinary assessment of children with problematic severe asthma and dysfunctional breathing. She is a member of the difficult asthma team at the Royal Brompton where she has developed the difficult asthma protocol and the National Registry for children with difficult asthma.
