Dr Grant Duthie is a senior lecturer at ACU Strathfield, joining the School of Behavioural and Health Sciences in 2016 after a 15-year career in elite sport. He has held numerous roles across a range of sports, and consults to several sporting organisations. Dr Duthie specialises in the analysis of team sport player tracking data. He completed his PhD in Exercise Physiology at the University of Queensland (UQ) in 2004; prior to this undertaking his undergraduate Bachelor of Applied Science (Human Movement) at The University of Ballarat.

Dr Duthie teaches sport and exercise science in the undergraduate program, specifically coordinating functional anatomy and the science and practice of resistance training at ACU’s Strathfield Campus. In addition, he also coordinates the Contemporary Issues in Sport Science, and the Data Analysis for High Performance Sport units within the Master of High Performance Sport course. Dr Duthie is currently supervising five PhD Students undertaking research in a wide variety of sport science and strength and conditioning projects.

Dr Duthie has previously worked in strength and conditioning roles within elite sport. Most notable was being a strength and conditioning coach at the 2000 Sydney Olympics and later working in both professional Rugby League and Rugby Union at a national and international level. More recently, he has provided athletic performance guidance for the Japan Rugby Union. He is also the lead data analysis for the Federation Internationale de Football Association (FIFA) Electronic Player Tracking System validation project. Further, Dr Duthie also consults to several sporting organisations, national and international, to provide assistance in the analysis, management, and visualisation of data.
