Montreal, Canada

I am a PhD student at the LIO laboratory (Laboratoire d'innovation ouverte en technologies de la santé) at ÉTS Montréal, working at the intersection of computer vision and biomechanics. My research focuses on human pose estimation and its application to markerless motion analysis. I also developed some tools, like a pose estimation framework to address the reproducibility problem deep-learning tasks.
