Hamilton will be a key collaborator in developing acute and chronic laboratory-based investigations in children and adults and sharing of technological/analytical expertise addressing the implications for human mechanistic research of inactivity physiology. Hamilton’s work has influenced and has been influenced by our observational study findings. His experimental approach and measurement techniques directly complement our laboratory-based investigations on the health impact of prolonged sitting.


Winthrop Professor Daniel Green

School of Sport Science, Exercise and Health - University of Western Australia

 

Green will provide opportunities for our fellows and students to extend their expertise in microvascular and macrovascular measurement methodologies with the potential to provide unique insights into mechanisms and dose response issues. Green will provide opportunities for fellows’ and PhD students’ involvement in laboratory-based investigations with children and adults, building capacities in the applications of novel vascular-function imaging approaches that can be applied to the assessment of changes related to experimentally-based variations in sedentary and physically active time.


Professor Robin Daly

School of Exercise and Nutrition Sciences - Deakin University

 

Daly will contribute to developing joint laboratory-based investigations examining the impact on markers of musculoskeletal health of interventions to reduce and break up prolonged sitting time in older adults; Daly will provide mentorship and learning opportunities for our fellows and PhD students in the applications of cutting-edge imaging modalities for examining mechanisms and markers relevant to musculoskeletal health; his guidance will be particularly valuable in interpreting and applying the broader message of sitting time and chronic disease in ways that are at relevant to older adults.


Dr Elisabeth Lambert

Human Neurotransmitters Laboratory - Baker IDI Heart and Diabetes Institute

 

Lambert provides insights and expertise as a leading expert in the assessment of sympathetic nervous function, which involves potentially significant, but as yet unexplored, factors associated with the adverse consequences of prolonged sitting. Her contributions will involve uses of microneurography and she has significant expertise in clinical investigations examining the effects of changes in posture on autonomic function and the effects of sympathetic nervous activation in the generation of cardiometabolic disturbances and end organ damage (cardiac, renal and vascular), particularly in overweight and obese adults.


Professor Nicola Lautenschlager

Department of Psychiatry - Melbourne University

 

Lautenschlager will provide opportunities for our fellows and PhD students to extend their expertise and experience in cognitive function assessment and brain function testing methodologies, including neuroimaging. This relates to the understanding of how sitting-related biological mechanisms may influence cognitive function. Leading expert in research relating to dementia, Alzheimer’s disease and prevention of age-associated cognitive decline; has recently published a state-of-the-art review on the influence of physical activity on brain ageing and dementia and underlying mechanisms with CI Dunstan’s collaborator A/Prof Kay Cox (University of Western Australia).

 

Theme 3: Interventions

Professor Ilse De Bourdeaudhuij

Department Movement and Sport Sciences - Ghent University

 

De Bourdeaudhuij will contribute her expertise in this CRE on the role of the environment as an influence on child, youth and adult sitting time and development of interventions. She is a clinical psychology and behaviour therapy researcher with expertise in interventions to promote healthy eating and physical activity and reduce sedentary behaviour, particularly among children and youth. She has been involved in 8 European Commission funded projects as partner or work package leader. She is a CI on the NIH-funded IPEN adult and adolescent projects (with CIs Owen and Salmon).


Associate Professor Mai Chin A Paw

Department of Public and Occupational Health - VU University Medical Center, Amsterdam

 

Chin A Paw will bring innovative methodologies in behavioural epidemiology and intervention mapping (a protocol for systematic development of interventions); and analysis of mediators (how does an intervention achieve its effects) and moderators (who responds to interventions). She will participate in Themes 2 and 3 through joint interventions to reduce sitting time in children and youth (FP-7 application to the European Commission pending; FP-7 International Staff Exchange Scheme funding 2010-13), and laboratory-based studies in youth (TOP grant).


Professor Stuart Biddle

School of Sport, Exercise and Health Sciences - Loughborough University, UK

 

Biddle will contribute his expertise in translation of research findings from this CRE to inform future recommendations, and will also assist with the integration of sedentary behaviour findings across the lifespan. He had a leading role in the development of sedentary behaviour guidelines in the UK. His primary expertise is in understanding the behavioural aspects of physical activity, sedentary behaviours and health. He has collaborated with CIs Salmon and Timperio in the exchange of a PhD student and post-doctoral fellow with the Deakin arm of our proposed program.


Professor Ester Cerin

School of Exercise and Nutrition Sciences - Deakin University

 

Cerin will bring expertise in applications of state-of-the-art statistical methods to the estimation of intervention effects, the identification of mechanisms and techniques of behaviour change, and the identification of person- and environment- effect modifiers of intervention-related changes. She is a behavioural scientist and biostatistician who has recently taken up a Chair at Deakin University after a mid-career phase in the USA and Hong Kong. Her contributions will involve the development and conduct of theoretically-based approaches and strategies for the analysis of data from intervention trials using advanced data-analysis methods.


Professor James F Sallis
