Research Scientist, Meta (Facebook) Reality Labs Email: cgchoe [at] fb.com
I'm a research scientist at Meta Reality Labs. Prior to joining Meta, I have spent 3 years in Samsung Research America researching and developing AI, computer vision and image processing algorithms for Samsung's flagship Galaxy smartphones. I received my Ph.D in Computer Vision from KAIST in 2018. I was a visiting researcher at Robotics Institute, CMU in 2015.
