My research focuses on three related topics: Landscape Evolution, Critical Zone Surface Processes, and Landscape Resilience. I investigate how tectonic activity, climate variability, extreme events, and human activities jointly influence the formation of mountain landscapes, the transport of materials, and landscape recovery after major disturbances.
I. In Landscape Evolution, I have studied the mudstone badlands of southwestern Taiwan, examining how rainfall, runoff, lithology, erosion, and tectonic settings control rapid landscape change. My research also extends to meander evolution, drainage-divide migration, and global drainage-basin geometry, with the aim of understanding whether landscape evolution across different environments is governed by common controls.
II. In Critical Zone Surface Processes, I focus on the relationships among landscape energy, hydrology, weathering, and material transport, and investigate how water, sediment, dissolved materials, large wood, and carbon are produced, stored, and transported within mountain Critical Zones. My current research at the Fushan Experimental Forest uses long-term observations to examine how landscape energy, hydrological connectivity, and solute export are related in a highly humid environment. I am also developing research on enhanced rock weathering and carbon dioxide removal. In addition, I combine deep learning with hydrological monitoring to quantify driftwood transport during typhoon-driven floods.
III. In Landscape Resilience, I investigate how mountain landscapes reorganize and recover after major disturbances. My research includes earthquake–typhoon interactions, bedload transport, landslides, and river-channel adjustment, as well as the use of environmental seismology to monitor changes in rivers and subsurface environments during and after extreme events. My goal is to better understand how extreme events alter sediment supply, river conditions, and recovery times, and to develop a framework for evaluating long-term landscape change and resilience in mountain environments.
