I am a CS PhD student at the Empirical Inference department of Max Planck Institute for Intelligent Systems and ETH Zurich, supervised by Prof. Bernhard Schölkopf and Dr. Dieter Büchler. I work on the intersection of robotics, 3D vision, and machine learning. My current research focuses on two main areas: generative modeling for motion generation, and in-context robot learning.

I obtained my master's degree in Electrical Engineering and Information Technology at ETH Zurich. I also spent time at Microsoft Mixed Reality & AI Lab in Zurich, Tencent AI Lab and Tencent Robotics X Lab.

Outside of academics, my hobbies include music, photography, doing various kinds of sports, and playing StarCraft II and League of Legends.
