Zan Gojcic Zan Gojcic Senior Research Manager
I'm a Senior Research Manager at NVIDIA in Zurich, leading a team focused on advancing neural reconstruction and generative world simulation for PhysicalAI. Our mission is to develop high-fidelity simulation environments that enable autonomous agents to be trained and evaluated in closed-loop systems.
