Overview
Background
Cristian Riveros-Matthey is a dedicated and highly motivated researcher with a strong academic background in biomechanics and motor control, holding a PhD from the School of Human Movement and Nutrition Sciences (HMNS) at The University of Queensland.
He has demonstrated expertise in applying advanced technologies for human movement analysis, including markerless 3D motion capture systems, force sensors, surface and high-density electromyography (hdEMG), and ultrasound imaging. He is also proficient in data analysis and signal processing using MATLAB and Python.
Cristian’s research focuses on musculoskeletal simulation and optimisation to investigate the principles underlying action selection and the cost functions that drive human movement in constrained locomotor tasks, such as cycling, level walking, and uphill walking.
