Nick is a BASES-accredited physiologist, Senior Lecturer in Applied Physiology, the sports sciences Laboratory Director, and Deputy-Chair of the Research Ethics Committee. He is actively engaged in research and scholarly activity.
Nick completed his undergraduate studies in Sport and Exercise Science (2005) at the University of Hertfordshire, and his Masters by Research the following year at the same institution. His thesis looked at carbohydrate metabolism and substrate utilisation during endurance cycling. After providing consultancy services to the Talented Athlete Scholarship Scheme (TASS) and England Athletics, Nick joined the English Institute of Sport at Bisham Abbey (South East), where he provided physiology support to Badminton England, UK Athletics and the Flatwater Kayak Olympic programmes. While at the EIS, he completed his BASES accreditation (2010).
In 2011, Nick won a Pro-vice Chancellor Research Scholarship to complete Doctoral studies at Brunel University London, under the supervision of Dr Lee Romer. During this time, Nick worked as a teaching fellow, won two Brunel travel grants, a BASES international conference grant, and a post-graduate prize for research. Following his Doctoral studies, Nick assumed a role at the GSK Human Performance Lab (West London), where he developed their Expert Science programme and science communication strategies. Nick joined Sheffield Hallam in 2016, where he now leads on the Applied Physiology module at level 6.
