About
Research and engineering for visual AI systems.
I am Chong Hou Choi, an AI researcher currently working on world models and real-time visual interaction. Previously, I was an AI Algorithm Engineer at Huawei's Hong Kong Research Center, where I had the opportunity to work with Dr. Rui Liu ↗. Before that, I was a Machine Learning Engineer Intern at Shanghai Artificial Intelligence Laboratory ↗ under the supervision of Dr. Yi Wang ↗.
My broader interests include visual generation, interactive AI systems, and AI infrastructure. I am particularly interested in exploring how visual intelligence can support education and learning.

Places I wander, music I love, and people I'm lucky to have beside me.
