Biography

I am a second year PhD student at Cornell University working with Prof. Noah Snavely. I am generally interested in computer vision, graphics, and machine learning. My recent research focuses on 3D reconstruction, motion analysis, and view synthesis.

I received my Bachelor's degree in Electrical Engineering from National Taiwan University (NTU) in 2018, and my Master's in Electrical Engineering from Stanford University in 2021. I have had the privilege to work with Prof. Li Fei-Fei, Prof. Jiajun Wu, Prof. Leonidas Guibas, Prof. Jure Leskovec, and Prof. Pan Li at Stanford. If you would like to learn more about me, please see my [ Résumé ] or contact me at yenyuchang [at] cs.cornell.edu.
