Biography

I earned my doctoral degree from the Advanced Interactive Technologies lab within the Institute for Intelligent Interactive Systems at ETH Zurich, supervised by Prof. Otmar Hilliges and Prof. Marc Pollefeys. In February 2026, I successfully defended my thesis, "Advancing Digital Humans Toward Personalized Human-Centric AI." My doctoral committee included Prof. Marc Pollefeys (ETH Zurich), Prof. Siyu Tang (ETH Zurich), Prof. Ming-Hsuan Yang (UC Merced), and Prof. Lingjie Liu (University of Pennsylvania). Prior to my PhD, I completed my Master’s degree in Computer Science at ETH Zurich in 2021.

My research interests lie in human-centric computer vision, spanning from human perception models, such as human recognition and pose estimation, to AR/VR digital humans, including 3D human reconstruction and generative modeling. You can find my previous projects in my homepage, google scholar, or LinkedIn.

Keywords: Digital Humans, Performance Capture, 3D Reconstruction, Body Pose Estimation.
