I am a second-year Ph.D. student at Intelligent Positioning and Navigation Laboratory, Department of Aeronautical and Aviation Engineering, Hong Kong Polytechnic University, supervised by Dr. Weisong WEN and co-supervised by Dr. Li-Ta Hsu. My research interests include perception-aided GNSS positioning and sensor fusion in highly challenging environments.
