Dr Yi-Chung Lin joined the SPRINT (Sprot, Performance, Recovery, Injury & New Technologies) research centre as a postdoctoral research fellow in 2022. He is currently working on a project funded by the National Football League to validate the use of inertial measurement units (IMUs) to assess lower-limb running kinematics that can be implemented in an elite sporting environment. The goal is to explore the risk factors associated with hamstring injury and re-injury in collegiate American Footballers.

Dr Lin completed his PhD studies at the University of Florida under the supervision of Professor B. J. Fregly. One of the highlights of his PhD work was to develop and implement a novel surrogate contact modelling approach to simultaneously calculate lower-limb muscle and knee-joint contact forces during gait.

Upon completion of his PhD studies, Dr Lin continued his research in biomechanical engineering as a Postdoctoral Research Fellow at The University of Melbourne under the guidance of Professor Marcus Pandy. His research focused on developing a novel computational method for non-invasively evaluating muscle function. Dr Lin has implemented this new approach to study muscle coordination during various activities, including walking, jogging, sprinting, and stair ambulation. Dr Lin also implemented an implicit method for solving optimal control problems called 'direct collocation' to predict the biomechanics of human walking and running. The direction collocation method allows researchers to predict the variables of interest simultaneously for human movement, independent of experimental data. He has used this method to investigate the effects of varying muscle-tendon parameters on the performance of maximum-speed sprinting.
