About me

I am currently an Applied Scientist II at Amazon Fauna Robotics. I received my PhD in Electrical and Computer Engineering from the University of Washington - Seattle in 2026, where my dissertation focused on “Building Multimodal AI Systems for Perceiving and Reasoning in 3D Space”. I also hold a Master of Science degree in Electrical and Computer Engineering from the University of Washington, and a Bachelor degree from the National Chiao Tung University in Taiwan.
