Dr Sarath Ranganathan
is an experienced paediatric respiratory physician, medical researcher and teacher.
Respiratory Physician
Since electing to subspecialise in respiratory medicine Dr Ranganathan’s posts in this
discipline have been in units with national and international reputations. His specialist training was undertaken at the
Royal Brompton and Great Ormond Street Hospitals. He took up his first consultancy in paediatric respiratory medicine at
the Royal Children’s Hospital, Melbourne, Australia, in 2004. The Royal Children's Hospital Melbourne is one of the world’s
leading paediatric hospitals. In 2008 he took up an academic position as Senior Lecturer in Paediatrics at the Brighton and
Sussex Medical School, UK before returning to the Royal Children's Hospital, Melbourne, Australia in 2010 and is now Director
of Respiratory Medicine
Areas of expertise:
- Cystic fibrosis
- Paediatric Asthma
- Allergy
- Paediatric bronchoscopy
- Tuberculosis and lower respiratory tract infection
Research
Dr Ranganathan has been invited to speak at plenary sessions of international conferences and has chaired
several international respiratory meetings. He is a member of the editorial board of the American Journal of Respiratory and
Critical Care Medicine (ranked first in both respiratory diseases and critical care medicine). He is a member of two Joint American
Thoracic Society / European Respiratory Society Task Forces: 1) ‘Standardization of Infant and Pre-school Pulmonary Function
Testing’ and 2) ‘Computer Tomography Scan and Lung Function during Childhood’. He has served on the Ethical Review Board of the
Royal Children’s Hospital Melbourne and the Executive Committee of the Thoracic Society of Australia and New Zealand. He currently
sits on the Research Advisory Committee of the Royal Australasian College of Physicians and is a member of the Stop TB New Diagnostics
Working Group, part of a joint UNICEF/UNDP/WHO collaboration.
Dr Ranganathan has extensive experience in the area of early detection of lung disease. He co-ordinated the London Collaborative
Cystic Fibrosis Study (LCCFS) of lung function and clinical status in infancy between December 1999 and November 2002 at the Institute
of Child Health, London. The LCCFS is a prospective longitudinal cohort study recruiting infants newly diagnosed with cystic fibrosis
(CF) from five paediatric centres in London, UK. The main aims of this study were to evaluate the role of new lung function techniques
in assessing the distribution of pulmonary function abnormalities at diagnosis and to examine the cross-sectional and longitudinal
associations of airway function with anthropometric measurements and clinical status in infants with CF. His research in this field has
led to the publication of several papers in high impact peer-reviewed journals (e.g. The Lancet and American Journal of Respiratory and
Critical Care Medicine) and the completion of his peer-reviewed PhD thesis entitled ‘Lung Function in Infants with Cystic Fibrosis:
Findings at Diagnosis and Changes with Time’. Dr Ranganathan has published technical and methodological papers in relation to the
development of complex pulmonary function techniques for use in infants and young children and is considered internationally to be an
expert in methods to detect early lung disease. He has written major reviews of work in this field and has been invited as guest speaker
to three international meetings in 2009/2010.
In 2006, Dr Ranganathan established the Melbourne wing of the Australian Respiratory Early Surveillance Team for Cystic Fibrosis
(AREST-CF) and founded the infant and pre-school pulmonary function laboratories at the Royal Children's Hospital Melbourne. He has
several competitively-gained research grants in clinical respiratory research.
Training
Dr Ranganathan has trained specialists in paediatric respiratory medicine from Ireland, Switzerland, Costa Rica,
Australia, Scotland and the United Kingdom. He has lectured at postgraduate sessions at international meetings, moderated symposia on
lung function testing and contributed chapters to two principal CF textbooks. He is a module leader and clinical academic tutor for
the Child Health course at the Brighton and Sussex Medical School.
