I am a final year PhD student in the Advanced Interactive Technologies group of the Institut für Pervasive Computing at ETH Zurich. My PhD supervisor is Professor Otmar Hilliges. I received my Master's degree in Information Engineering from University of Konstanz with a focus on interactive systems. Before joining the Advanced Interactive Technologies Lab I worked as a research assistant at the HCI group of University of Konstanz. My research interest lies in the area of optimization algorithms that improve human machine interaction. During my PhD studies, I was working on the optimization of quadrotor camera trajectories according to user goals, learning Mixed Reality labeling according to users' preferences or tasks and modeling human task interleaving for intelligent notification systems with Reinforcement Learning.
