Since January 2025, I am a postdoc researcher at Inria Paris, Willow team. My thesis, Algorithmic and Computational Foundations of Differentiable Collision Detection, was supervised by Josef Sivic (CTU Prague), Vladimir Petrik (CTU Prague) and Justin Carpentier (INRIA Paris). Before that, I received a Master’s degree from ENPC Paris in Computer Science and Applied Mathematics.

My research focuses on (differentiable) physics simulation and mathematical optimization in the context of robotics.
