Welcome to explore my research! My research focuses on modeling the uncertainty of GeoData, especially LiDAR point clouds, and integrating ML to improve data quality. The ultimate goal is to support uncertainty-sensitive downstream applications!

If you have an interest in LiDAR/SLAM or uncertainty, or if you're simply curious about my work, please don't hesitate to reach out. Moreover, I am open to advising Bachelor's and Master's theses, as well as discussing potential collaborations!
