He has recently led extreme heat policy development for Sports Medicine Australia, Tennis Australia (including the Australian Open), Cricket Australia, and the National Rugby League (including the 2017 Rugby League World Cup).

He is Senior Deputy Editor for Journal of Science and Medicine in Sport, and an Editorial Board member for Journal of Applied Physiology, Medicine and Science in Sports and Exercise (MSSE), and Energy & Buildings. In 2017, he was the recipient of the Vice-Chancellor’s Award For Excellence: Outstanding Research and Teaching a 2-year University of Sydney Research Accelerator (SOAR) Fellowship. In 2018 & 19, he received 2 consecutive SUPRA Research Supervisor of the Year awards.
