Hi, I’m Julian. I’m an HCI Researcher and PhD Student at the Media Informatics Group at LMU Munich. My research explores how humans interact with digital systems and how we can augment this powerful synergy. I focus on enabling and enhancing collaboration in XR, with particular interest in multi-user interaction and the dynamics of human–AI collaboration within these immersive environments. I investigate how XR can enable interactions, perspectives, and experiences that are not possible in the physical world alone and how familiar real-world interactions may require rethinking when translated into immersive contexts. As XR systems increasingly blend with our physical surroundings, my work also considers the critical question: how much virtuality do we want in our (XR) reality?

My broader research interests include Perception & Interaction in XR, Human Augmentation, Virtual Design & Engineering, Interactive Media Art, and Future Applications of XR. With a background in Electrical Engineering and IT from TU Darmstadt, I bring expertise in hardware prototyping and systematic problem-solving to interdisciplinary challenges at the intersection of technology, design, and human experience.
