Yixuan Yang Hi there! My name is Yixuan Yang (杨翊玄, pronounced 'Yee-shwen Yang'). I am currently a Ph.D. candidate at DCS, University of Warwick, UK, supervised by Prof. Victor Sanchez and Prof. Feng Zheng (SUSTech, China). I received my Master degree at CSE, The Chinese University of Hong Kong (CUHK) in 2020. Previously, I obtained my Bachelor's degree in the School of Computer Science in 2019 at Northwest University, China. Now, I am an intern at Shanghai AI lab, working on 3D scene generation and 3D reconstruction. Besides, I am also a photography enthusiast, I share some of my photography works in this page.
