I am an M.S. student in Multimedia at National Yang Ming Chiao Tung University (NYCU), advised by Prof. Yu-Lun Liu and Prof. Yu-Ting Wu in the Computational Photography Lab.

Previously, I received my bachelor's degree in Computer Science from National Taipei University (NTPU). During this time, I conducted my undergraduate project under the supervision of Prof. Yu-Ting Wu in the Multimedia & Visual Computing Lab.

Research

My research lies at the intersection of computer vision, machine learning, 3D geometry, and 4D reconstruction.


Projects

My projects span computer vision, robotics, and image processing, bridging research and real-world applications. Beyond research, I also develop and maintain production apps with Swift and SwiftUI.
