Justen is an Associate Professor in the School of Curriculum Teaching and Inclusive Education. Justen is also the Associate Dean Staffing and Strategy within the Faculty of Education. Justen's research aims to transform sport and physical education settings to become more inclusive, diverse and healthy sites for participation. As a sociologist, Justen achieves this by challenging the entrenched boundaries that tend to limit and marginalise. His research demonstrates a commitment to widening notions of sport and physical education participation to encompass more informal and diverse sporting forms that prioritise meaningful social connection. Justen situates problems within complex socio-ecological systems, utilises mixed-method approaches to understand these problems and works closely with industry partners and other exceptional research scholars to generate outcomes. Consequently, Justen's research continues to be supported by a range of funding partners. Recent projects supported by the prestigious and highly competitive Australian Research Council include:

• 'Informal sport as a health and social resources amongst diverse young people' ($250,000)
• 'United on the field? Enhancing equity and inclusion in community sport'  ($404,954)

Justen has particular methodological expertise in the design and validation of measures for research utilising RASCH analysis.

EDF2171 Motor Control and Skill Acquisition: This unit explores the discipline of human movement, particularly how humans acquire and refine a broad range of movement skills. The study of motor control and skill acquisition is a broad area that uses foundational biophysical knowledge together with elements of psychology, sociology and understanding of growth and development to explore how and why the human body moves.

EDF4171 Advanced Sport and Exercise Science: This unit expands upon foundational physiological, kinesiological and psychological understandings of human movement science within health and physical education.
