Dr Grace O'Malley graduated from Trinity College Dublin in 2004 with a BSc (hons) in Physiotherapy. Since graduation she has worked clinically in the area of paediatrics, gaining experience in respiratory, neurological, musculoskeletal and endocrinological medicine. Her interests in orthopaedics and endocrinology were further distilled via a research MSc (TCD) which explored the musculoskeletal effects of childhood obesity. Thereafter, Grace was awarded a Fulbright scholarship to the Yale University School of Medicine where her research explored the pathophysiology of Type 2 diabetes in childhood obesity and the development of effective treatment strategies. Grace was awarded a HRB Fellowship to undertake a PhD in Medicine (Epidemiology and Public Health) in University College Cork and her thesis investigated the development and evaluation of childhood obesity treatment delivered via traditional and novel telehealth methods. Her post-doctoral work was undertaken at University of Southern California and the University of California, Davis in the field of telemedicine/mobile-health.

Grace works clinically at Temple Street Children's University Hospital where she has led the development and implementation of a paediatric obesity service. Her research interests encompass the assessment and management of paaediatric obesity and include: evidence-based assessment of obesity and it's related co-morbidites; the application of behaviour change theory in treatment strategies; the use of exercise therapy for the management of chronic disease; the systematic review and meta-anlaysis of incentives to promote physical fitness and the feasibility of using telehealth and mobile-health strategies to enhance the clinical effectiveness of obesity treatment. In addition to clinical responsibilities, Grace works in a voluntary research, teaching and administrative capacity with the Association for the Study of Obesity on the Island of Ireland (; the Childhood Obesity Task Force of EASO; the European Childhood Obesity Group and the Paediatric group of the World Confederation of Physical Therapists.
