Sammy Christen

I am a postdoctoral researcher in the robotics team at Disney Resarch Zurich. I obtained my PhD at the AIT lab, ETH Zurich, supervised by Professor Otmar Hilliges and co-supervised by Professor Jemin Hwangbo. My research focuses on human-robot interaction and dexterous robotic grasping. During my PhD, I spent time at the NVIDIA AI Robotics Lab in Seattle and at Meta Reality Labs.
