About Me

Dr. Xiwei Bai (Member, IEEE) received her Ph.D. degree in the Department of Aeronautical and Aviation Engineering from The Hong Kong Polytechnic University, in 2023. Currently, she works as a postdoctoral researcher with the Department of Aeronautical and Aviation Engineering, The Hong Kong Polytechnic University. Dr. Bai is a member of IEEE, and she serves as a reviewer in professional journals and conferences related to her research topics. Her research interests include visual-inertial navigation systems and visual-aided GNSS positioning for autonomous vehicles in urban canyons.

Hoping our research will make things better for people, businesses, and society as a whole.
