Current four topics that I work with my students range from evolving landslide topography, effective 3D geologic mapping, landslide hazard modeling, and structural geology & tectonics. The details of the research topics and recent leading contributions are as follows:

Topic I: Multi-period and multi-source high-resolution DEMs for studies of landslide and erosion processes.
[主題一：多期多源高解析度數值高程模型應用於山崩特性與侵蝕過程研究]
Two representative papers for this topic are as follows:
