Dr Dylan Cliff is an Associate Professor in the School of Education at the University of Wollongong, Australia. His area of expertise is in children's movement behaviours, including physical activity, sedentary behaviour, and digital technologies. He aims to promote healthy levels of movement behaviours among children by enhancing our understanding of how movement behaviours interact to influence children's development. This understanding can inform policies and practices that support children's movement behaviours.
Dylan has been awarded over $42 Million in competitive funding and published more than 130 peer-reviewed journal articles that have been cited more than 7,800 times. He has a h-index of 42.
Dylan currently leads the Sleep and Activity Database for the Early Years (SADEY), funded by an Australian Research Council. This is an international project to unite researchers globally to develop an analyse a pooled database of young children's movement behaviours and health and development outcomes. He is also a Chief Investigator on the ARC Centre of Excellence for the Digital Child. This centre includes six Australian universities (UOW is one of these) and 33 academic and industry partner organisations from Australia, Europe, Asia and America as they embark on a seven year, transdisciplinary research program that involves experts from education, health and digital and social connectedness.
Dylan was also a leadership group member for the development of the Australian 24-hr Movement Guidelines for the Early Years (birth to 5 years), and for the Australian 24-hr Movement Guidelines for Children and Young People (5 to 17 years).
