I am Ruofei Du,
Interactive Perception & Graphics Lead,
at Google Labs.

Welcome to ruofei's reality! Ruofei Du serves as the Interactive Perception & Graphics Lead at Google AR and works on creating novel interactive technologies for virtual and augmented reality. Du's research covers a wide range of topics in VR and AR, including XR interactions, visual programming, augmented communication, XR social platforms, digital human, foveated rendering, accessibility, and deep learning in graphics. Du serves as an Associate Chair in program committes of CHI and UIST; an Associate Editor of Frontiers in Virtual Reality and IEEE TCSVT. In their own words: I am passionate about inventing interactive technologies with graphics, perception, and HCI. See my research, artsy, projects, youtube, talks, github, and shadertoy demos for fun! bio

• 2/27/23: One paper about digital human is accepted at CVPR 2023!
• 2/24/23: Gave an onsite talk at the University of Iowa Computing Conference sponsored by ACM.
• 2/21/23: Three papers, one demo, and one LBW paper are accepted by ACM CHI 2023. More news...

Prior to UMD, I received my B.S. degree from ACM Class, Computer Science at Shanghai Jiao Tong University (SJTU). I served as the vice president of the ACM Class and a undergraduate research assistant in the BCMI Lab. From Jul. 2012 to Feb. 2013, I worked as a full-time intern at Microsoft Research Asia working on 3DVAR: From 3D reconstruction To Virtual and Augmented Reality while serving as the Chief Technology Officer at the ARD Intern Community of Microsoft Asia-Pacific Research & Development Group.
