Dr Nicholas Tiller MRes, PhD, PGCert, FHea

Senior Lecturer in Applied Physiology

Summary

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.

  • About

    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.

  • Research

    Ongoing projects relating to: pulmonary function and airflow dynamics in response to cold-water immersion; ultra-endurance physiology; cardiorespiratory responses to indoor climbing; the efficacy of CPR in the exercise training environment.

    The 100-Peaks Challenge (principal researcher and physiology consultant). This is a collaborative project between Sheffield Hallam University, University College London, Brunel University, and Anglia Ruskin University, I which we are investigating the physiological responses to extreme-endurance exercise. 

    Pulmonary function following cold-water ingestion: challenging the current guidelines on pulmonary function testing (collaborative project with Dr Louise Turner).

    Cardiovascular profiles of elite competitive rock climbers (collaborative project with NHS medics and Newcastle University).

    Influence of multi-day marathon running on pulmonary function (principal researcher).  

    Masters project supervisor: Pre-exercise hypocapnic hyperventilation as an ergogenic aid.
