Respiratory Medicine Research

We have been conducting research into paediatric respiratory conditions since 1998, when our research unit was established as The Children's Chest Research Centre. Located at The Children's Hospital at Westmead, our clinical research team conducts research projects which have changed the way children with respiratory illnesses are treated.

A particular strength of our research team is undertaking clinical trials of new ways of diagnosing, investigating and treating diseases of the respiratory system. We have also established a number of important internal and external research collaborations.

Respiratory medicine is led by Associate Professor Hiran Selvadurai. For general enquiries please contact the department secretary, Debra Roberts-Jones:
