Associate Professor Kathryn Ramsey is a National Health and Medical Research Council (NHMRC) Emerging Leader (EL2) Fellow and Co-Head of Children’s Lung Health at The Kids Research Institute Australia.
Kathryn received her PhD in 2013 from the University of Western Australia and began her postdoctoral career in the longitudinal surveillance of infants and children with cystic fibrosis at The Kids Research Institute Australia. She was awarded an NHMRC Early Career Research Fellowship in 2015 to undertake research training in airway mucus biology at the University of North Carolina, USA. She then received a Swiss National Science Foundation Ambizione Fellowship in 2017 to lead the follow-up of a national cystic fibrosis cohort at the University of Bern, Switzerland.
She returned to The Kids Research Institute Australia in 2021 to co-lead the Children’s Lung Health team. Kathryn leads a translational research program to understand disease pathophysiology and improve outcomes in children with muco-obstructive lung diseases, including cystic fibrosis, bronchiectasis, and primary ciliary dyskinesia.

Projects
WA Aboriginal Child Health Survey (WAACHS) Data Linkage Study
This study is a partnership between researchers, the Aboriginal community and government to provide evidence for policy and practice addressing high priority health and wellbeing issues for Aboriginal children and families.
Kids Easy Breathing Study
As both bronchiolitis and bronchiectasis are diseases of the airway surface, we will comprehensively study the airway surface and factors affecting the airway surface in infants hospitalised with bronchiolitis.
October 2023
Western Australia Paediatric Bronchiectasis Cohort
Bronchiectasis is a chronic lung disease that impairs quality of life and reduces life expectancy.
Published research
Lung structural and functional impairments in young children with cystic fibrosis diagnosed following newborn screening – A nationwide observational study
Non-invasive and sensitive clinical endpoints are needed to monitor onset and progression of early lung disease in children with cystic fibrosis (CF). We compared lung clearance index (LCI), FEV1, functional and structural lung magnetic resonance imaging (MRI) outcomes in Swiss children with CF diagnosed following newborn screening.
Simultaneous multiple breath washout and oxygen-enhanced magnetic resonance imaging in healthy adults
Lung function testing and lung imaging are commonly used techniques to monitor respiratory diseases, such as cystic fibrosis (CF). The nitrogen (N2) multiple-breath washout technique (MBW) has been shown to detect ventilation inhomogeneity in CF, but the underlying pathophysiological processes that are altered are often unclear.
European Respiratory Society/American Thoracic Society technical statement: standardisation of the measurement of lung volumes, 2023 update
This document updates the 2005 European Respiratory Society (ERS) and American Thoracic Society (ATS) technical standard for the measurement of lung volumes. The 2005 document integrated the recommendations of an ATS/ERS task force with those from an earlier National Heart, Lung, and Blood Institute workshop that led to the publication of background papers between 1995 and 1999 and a consensus workshop report with more in-depth descriptions and discussion.
Arsenic and respiratory disease
Arsenic is the only environmental toxin that has been linked to both malignant and nonmalignant respiratory disease following ingestion, rather than inhalation, making arsenic a unique toxicant to the respiratory system. Chronic exposure to arsenic has been associated with the development of respiratory symptoms, impaired lung function, and chronic lung disease.
Feasibility of unsedated lung MRI in young children with cystic fibrosis
Monitoring disease progression in childhood bronchiectasis
Bronchiectasis (not related to cystic fibrosis) is a chronic lung disease caused by a range of etiologies but characterized by abnormal airway dilatation, recurrent respiratory symptoms, impaired quality of life and reduced life expectancy.
Normative data for multiple breath washout outcomes in school-aged Caucasian children
The multiple breath nitrogen washout (N2MBW) technique is increasingly used to assess the degree of ventilation inhomogeneity in school-aged children with lung disease. However, reference values for healthy children are currently not available.
Normative multiple-breath washout data in school-aged children corrected for sensor error
Quality of life is poorly correlated to lung disease severity in school-aged children with cystic fibrosis
There is no data exclusively on the relationship between health-related quality-of-life (HRQOL) and lung disease severity in early school-aged children with cystic fibrosis (CF). Using data from the Australian Respiratory Early Surveillance Team for Cystic Fibrosis (AREST CF) we assessed the relationships between HRQOL, lung function and structure.
Preschool Multiple-Breath Washout Testing. An Official American Thoracic Society Technical Statement
Consensus recommendations are outlined to direct preschool device design, test performance, and data analysis for the MBW technique
The clinical utility of lung clearance index in early cystic fibrosis lung disease is not impacted by the number of multiple-breath washout trials
This study aimed to determine if relationships between LCI and clinical outcomes of CF lung disease differ when only two acceptable MBW trials are assessed.
Effect of posture on lung ventilation distribution and associations with structure in children with cystic fibrosis
Background: We assessed the effect of posture on ventilation distribution and the impact on associations with structural lung disease.
Multiple-breath washout outcomes are sensitive to inflammation and infection in children with cystic fibrosis
The lung clearance index may be a useful surveillance tool for monitoring the presence and extent of lower airway inflammation and infection
Air trapping in early cystic fibrosis lung disease-Does CT tell the full story?
Mosaic attenuation on expiratory chest computed tomography (CT) is common in early life cystic fibrosis (CF) and often referred to as "air trapping"
End-inspiratory molar mass step correction for analysis of infant multiple breath washout tests
We aimed to evaluate the use of the EIMM-step method in a broad range of infants.
A systematic approach to multiple breath nitrogen washout test quality
The application of the systematic review improved inter-observer agreement but did not affect reported multiple breath washout outcomes
Lung Clearance Index and Structural Lung Disease on Computed Tomography in Early Cystic Fibrosis
Lung clearance index may be a useful surveillance tool to monitor structural lung disease in preschool and school-age children with cystic fibrosis
Impact of lung disease on respiratory impedance in young children with cystic fibrosis
The present study investigated whether lung function measured by forced oscillation technique would be impaired in the presence of infection,...
Progressive ventilation inhomogeneity in infants with cystic fibrosis after pulmonary infection
This study aimed to determine how pulmonary inflammation & infection impacts on ventilation distribution throughout early life in people with cystic fibrosis.
Early respiratory infection is associated with reduced spirometry in children with cystic fibrosis
We hypothesized that the presence of these markers of cystic fibrosis lung disease in the first 2 years of life would be associated with reduced lung...
