[>> Homepage]My research interests focus on applying multiple approaches, particularly high-resolution Lidar-derived digital elevation models, to better understand the development of geologic structures and surface processes that continuously shape the landscapes on Earth. The current four topics that I worked 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 in papers are as follows:

Topic I: Multi-period and multi-source high-resolution DEMs for studies of landslide and erosion processes.
