Research
My research interests focus on state estimation and spatial AI for robotics, including probabilistic sensing, localization, mapping, perception and planning of autonomous ground, aerial and underwater vehicles:
Consistent Visual-inertial Navigation systems (VINS)
Simultaneous localization and mapping (SLAM)
Nonlinear state estimation and optimization theory
Information fusion, sensor calibration and system parameter identification
