Dr Carroll has helped developed the technique of nasal ventilation and has applied it for use in Cystic Fibrosis. She was involved in the discovery that nebulised heparin thins sputum so making it easier to expel. Currently she is involved in a large number of commercial and academic research projects, testing and advising new treatments for people with CF. She has a particular interest and is an international expert in studies using new molecular techniques to better identify the bacteria that cause lung infections. She has a large research portfolio consisting of phase 1 to phase III trials, looking at CFTR modulators and novel treatments. She is an active member of the European Cystic Fibrosis Society Clinical Trials Network (ECFS-CTN), European Lung Network (ERN), and CF Trust Clinical Trials Accelerator Platform Centre.

Major grants:

  • Co-applicant BRC

  • North American Cystic Fibrosis Foundation

  • CF Trust,  Clinical Trials Accelerator Platform Centre- Early Phase Grant

  • NIHR RFPB - Exercise as Airway Clearance Technique

  • BRONCH UK – MRC Funded – Bronchiectasis Biobank

Impact example:


Recent publications in PCD illustrates whole genome sequencing is revealing a greater number of patients in Bronchiectasis clinics that have PCD than previously thought, thus speaking to an unmet need.
