I am an Assistant Professor for Mobile Human-Computer Interaction at TU Darmstadt where I lead the Urban Interaction Lab. My research follows the vision of seamless mobile interaction in and with the physical world, where digital information, AI agents, and physical environments merge into a unified eXtended Reality. Towards this vision, I explore novel interaction techniques for mobile XR and collaboration with AI systems. My approach is informed by a deep understanding of body-centric, tangible and haptic interfaces, as well as strong technical expertise, aiming to make the interaction more efficient and accurate but also more enjoyable and fun.
