About

[CV] [Google Scholar]

I am a researcher in the Interactive Media (IMG) Group at Microsoft Research Redmond. My research interests lie broadly in computer vision, robotics and computer graphics and I work on various topics related to 3d scene reconstruction from images and video. These topics include structure from motion, SLAM, visual odometry, stereo matching, optical flow and scene flow, multi-view stereo, photometric stereo, image-based localization and place recognition. I am interested in applications ranging from 3D scanning, depth sensing, augmented reality (AR) and building computer vision-aided autonomous UAVs.

I received my M.S. and Ph.D. from the University of North Carolina at Chapel Hill where I studied topics in 3D reconstruction and multi-view geometry in computer vision.
