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 interests are in the areas of machine learning and computer vision.
