Ian is a Senior Lecturer in Sport Biomechanics in the Cardiff School of Sport and the Biomechanics Laboratory Director. He joined the School in 2006 as a postdoctoral research fellow, and became a lecturer in 2009. In the time since, Ian has made a significant contribution to the School's research profile, as well as the Sport and Exercise Science degree programme. He was included in the School's highly rated 2014 REF submission and played a key part in developing the new BSc in Sport and Exercise Science pathway in his previous role as discipline director for biomechanics.

Research / Publications

My research focuses on mechanical analysis of sporting gait, particularly sprint running. I am specifically interested in evaluating and characterising elite sprinting through the use of musculo-skeletal modelling of the lower extremity, and investigations of the step length-step frequency relationship. I also have an interest in applying these findings to other sports in which sprinting plays an important role in performance.
