Siyun Liang

I am a PhD student in the Computer Graphics research group at the University of Tübingen and the Max Planck Institute for Intelligent Systems, supervised by Prof. Dr. Hendrik Lensch.

Prior to my PhD study, I completed my Master's degree in Informatics at the Technical University of Munich, where my thesis was supervised by Dr. Michael Niemeyer and PD Dr. Federico Tombari. I hold a Bachelor's degree in Software Engineering from Southeast University, where I completed my undergraduate thesis at SAP Labs China.

Previously, I interned at the National Institute of Informatics, supervised by Dr. Huy H. Nguyen and Prof. Dr. Isao Echizen.

My research interests include 3D/4D reconstruction and understanding, with a current focus on open-vocabulary understanding.
