I study GNSS positioning and signal processing, with interests in resilient timing, multi-sensor fusion, and the connection between algorithms and working systems. I also explore vision-language navigation and embodied intelligence.
- Positioning & timing — GNSS receiver algorithms, spoofing detection, time synchronization, and RTK.
- Signals & sensor fusion — Signal quality estimation, data compression, state estimation, and graph optimization.
- Robotics & embedded systems — Vision-language navigation, embodied AI, FPGA development, and hardware–software co-design.
