The combination of more than 30 years experience as a medical practitioner (20 of which were dedicated to the health care needs of people with intellectual disability) and more than 16 years as a public health researcher (specialising in intellectual disability) underlies a strong commitment to ensuring that research findings translate into better outcomes across multiple lifestyle domains for people with intellectual disability and their families.
Main focus of research:
– Epidemiology of intellectual disability and associated syndromes (particularly Down syndrome and Rett syndrome) to better understand incidence, patterns, risk and protective factors
– Management and treatment of health conditions associated with intellectual disability (particularly conditions associated with Down syndrome and Rett syndrome) to inform individual and family decision-making and improved clinical practice
– Measurement of quality of life issues for people with intellectual disability and their families to better inform policy and practice responses
– Improved understanding of influences and issues across the life-course, including during the pre and peri-natal period and during important developmental milestones and transitions
