Kay Pompetzki (fmr Hansel)

Kay joined the Intelligent Autonomous Systems (IAS) Lab as a Ph.D. student in May 2021. He is interested in experimenting and researching with robots, exploring new concepts in artificial intelligence such as machine learning, reinforcement learning or deep learning, and thereby discovering interdisciplinary connections between various academic disciplines.

Before starting his Ph.D., Kay completed his Bachelor's degree in Applied Mathematics at the RheinMain University of Applied Sciences and his Master's degree in Autonomous Systems at the TU Darmstadt. His thesis, "Probabilistic Dynamic Mode Primitives", was written under the supervision of Svenja Stark and Hany Abdulsamad.

During his academic research, Kay had the invaluable opportunity to visit the Intelligent Robotics and Biomechatronics Laboratory led by Prof. Hasegawa as a visiting scholar from May 2023 to July 2023. Part of the Department of Micro-Nano Mechanical Science and Engineering at Nagoya University, the lab is renowned for its fundamental and applied studies on mechatronics technologies for advanced human assistance systems. In November 2024, Kay joined the German delegation for the Junior Expert Exchange (JEX) program, engaging in high-level discussions on robotics and AI policy with Japanese ministries and academic institutions. Building on these experiences, he served as lecturer in the Physical AI lecture series, sharing insights on machine learning in robotics at the Matsuo-Iwasawa Lab of the University of Tokyo in spring 2025.
