Sonia Cheng

Dr. Sonia Cheng is a Lecturer in the Discipline of Physiotherapy at the School of Health Sciences, University of Sydney. She is affiliated with the Faculty of Medicine and Health and the Charles Perkins Centre. Her research focuses on chronic respiratory diseases, particularly chronic obstructive pulmonary disease (COPD), sedentary behavior interventions, and pulmonary rehabilitation strategies. She leads projects like the 'Digital Discharge Education and Secondary Prevention of Heart Disease' and investigates airway clearance techniques in bronchiectasis.

Her academic background includes studies on physical activity patterns in COPD patients during pulmonary rehabilitation and the validity of step-counting for sedentary behavior assessment. She has secured grants such as the 2022 '24-hour physical behaviours in people living with chronic disease' and the 2016 'feasibility of a sedentary time reduction intervention in COPD.'

• Current Students: Tiffany ELLIS (Heart Disease Discharge Education), Mitchell TAYLOR (Airway Clearance in Bronchiectasis)
• Key Grants: Faculty of Medicine and Health/New Academic Staff Funding (2022), Physiotherapy Research Foundation/Seeding Grant (2016)

Research interests include behavioral interventions to reduce sedentary time, physical activity epidemiology, and the application of digital tools in healthcare education. Her work spans clinical trials, systematic reviews, and observational studies in respiratory and chronic disease management.
