Prof Connett is a Professor of Paediatric Respiratory Medicine at the University of Southampton. He leads the Regional Paediatric Cystic Fibrosis (CF) Service, and is a specialist respiratory paediatrician accepting referrals from across the South of England. 

His research interests include CF microbiology, adherence, the benefits of exercise in CF, testing the efficacy of new CF treatments and assessing their impacts on future care needs. He is particularly interested in the extent to which asthma might be an autonomic, cue and context conditioned response occurring as a result of antenatal and early childhood factors and the implications this has for clinical care.

Impact example:

Southampton is a key centre for the design and delivery of Phase 3 clinical trials of CF transmembrane conductance regulator modulators. We are a founding member of the UK’s CF clinical trials accelerator platform. We have extended our role to include early phase development of novel treatments to meet the needs of people with CF who have uncommon genotypes and who are not responsive to currently available therapies.
