About Me

I am a PhD student at the Sensing, Interaction & Perception Lab, ETH Zurich with Prof. Christian Holz . My research lies at the intersection of Computer Vision, Digital Humans, Mixed Reality, and Human-Computer Interaction, with a particular focus on egocentric human motion modeling and estimation.

During my research journy, I was fortunate to collaborate with Larissa Laich and Dr. Patrick Snape from Meta Reality Labs, Zurich. Before starting my PhD, I got my Master’s degree in Computational Engineering Science from RWTH Aachen University. I wrote my Master’s thesis at the Computer Vision Lab, ETH Zurich, with Prof. Kai Zhang and Prof. Radu Timofte, supervised by Prof. Luc Van Gool and Prof. Bastian Leibe. Before that, I did a visiting research with Dr. Shuang Li and Prof. Jianwei Zhang at the University of Hamburg. Besides, I also worked with Dr. Jörg Stückler at Max Planck Institute for Intelligent Systems, and with Dr. Dengxin Dai at Max Planck Institute for Informatics.

Collaboration

If you are a motivated BS/MS student and would like to write your thesis with me, you are welcome to drop me an email. The current available thesis projects can be found at our lab's website SIPLAB (inside the ETHZ network) or SiROP (for logged in users). If you have any questions about my research or would like to collaborate with me, please also reach out to me.
