Junjiao

Hi, I am Junjiao Tian!

I am a PhD student in the Robotics Perception and Learning Lab (RIPL) at Georgia Tech and advised by Prof. Zsolt Kira. I previously worked as a research assistant in the Bot Intelligence Group (BIG) at CMU, supervised by Prof. Jean Oh. My research interest is computer vision with applications to AR/VR.
