Intro

About: I am a final-year Ph.D. student in the Department of Computer Science & Engineering, HKUST, advised by Prof. Long Quan. Previously, I obtained my bachelor degree from Peking University, double major in machine intelligence (EECS) and psychology. As an undergraduate research intern, I spent time at UC Berkeley and worked on Captcha recognition, hosted by Prof. Dawn Song. I also develop algorithms for Altizure from Day 1, where we are doing 3D reconstruction in an unprecedented scale. If you are interested in joining or collaborating, please drop me an email.

Research interests: My research interests lie in large-scale Structure-from-Motion, SLAM and related optimization problems. I aim to do research that accomplishes myself, enlightens peers and benefits the greater good.
