Puze joined Intelligent Autonomous Systems in Aug 2019 as a Ph.D. student. He work with Davide Tateo and Jan Peters within the research group Safe and Reliable Robot Learning. His research interests include robotics, reinforcement learning, controlling, and human-robot collaboration. Puze is looking for new approaches for robots to learn collaborative tasks that enable robots to assist humans in different scenarios.
Before starting his Ph.D., Puze completed his Master's degree in Computational Engineering Science at the Technische Universitaet Berlin. During his study, Puze's previous work focused on robot fundamental algorithms and safety problems during human-robot interaction. His master thesis "Industrial Robot Motion Control depending on the Distance between Human and Robot" was under the supervision of Prof. Dr-Ing. Jörg Krüger and Martin J. Rosenstrauch.
