Dr Matt Brearley

University Fellow

Dr Matt Brearley is an occupational heat stress consultant, conducting and applying research to guide industry practice. In doing so, Matt has developed a reputation as 'The Heat Guy', for his unrelenting pursuit of maximising human performance in challenging environments. He has worked with a wide range of industries including mining, construction, utilities, law enforcement, transportation, emergency response, and the military. 

His research has quantified the physiological impost of working in the heat, and examined heat acclimatisation and cooling strategies in the field. Matt introduced crushed ice ingestion to occupational settings in 2006, and continues to research the potential of this novel cooling strategy in harsh climates. Such work has been acknowledged with awards for research and innovation, best conference paper and presentations and recognition by the Australian Institute of Policy and Science.

Commencing his career in elite sport settings, Matt previously worked for the Northern Territory Institute of Sport and National Heat Training and Acclimatisation Centre, and was the heat specialist for the Australian team in the lead up to, and during the 2008 Olympic Games in Beijing, China.
