Gil received his PhD in Biomedical Engineering from the Technical University of Catalonia in 2015. He did a six-month PhD stay at the University of Florida (2012-2013). He worked in optimization and synergy approaches for studying muscle redundancy during walking. In 2015 and 2016 he worked as a postdoctoral researcher at KU Leuven (Belgium) developing predictive simulations based on direct collocation to estimate foot-ground and human-exoskeleton contact parameters and predict the collaborative movement of a subject with an exoskeleton. In September 2016 he got a position at the Department of Mechanical Engineering at the Technical University of Catalonia as Assistant Professor, and in 2021 as Associate Professor. In 2017 he was OpenSim Visiting Scholar. In 2020 he got a fellowship to do a research stay at Northwestern University (Illinois, USA). His current research lines are focused on biomechanical modeling, on integrating methods to obtain faster and more accurate biomechanical motion analysis results, and biomechanical predictive simulations based on optimal control.
