Assistant Professor (W2, tenure track) · Human-Computer Interaction
Department of Computer Science, TU Darmstadt
I lead the Human-Computer Interaction group at TU Darmstadt. My research lies at the intersection of Extended Reality, Human-AI Interaction, and the safety, security and ethics of these technologies. I study how AI-driven immersive systems can alter what people perceive, remember and decide, and I build systems and safeguards that keep this influence beneficial and under the user’s control.
Research
Perceptual manipulations and computational deception
Techniques that exploit the limits of human perception, such as redirected walking, can be misused to steer users without their awareness. We study these manipulations in XR, from false memories through source confusion to generative AI that produces deceptive designs on its own.
Engineering interaction for AI-driven XR
We build hardware and software for interaction, feedback and collaboration in AR and VR, from bringing non-HMD users into shared VR (ShareVR, FaceDisplay) to real-time generative models running on headset passthrough.
