Subsurface logs and stratigraphic correlation
Pairwise correlation of cores and well logs, and basin-scale preparation of log data.
Research · Interests and projects
Research
I study the intricate interplay between near-surface processes, which shape the Earth’s topography. These processes are tightly associated with tectonic activity, climate forces, and sediment redistribution over time and space. A significant amount of my time was dedicated to studying the genesis of the Coastal Range of eastern Taiwan, from a subsiding syn-orogenic deep-marine sedimentary basin to a rapidly rising and eroding mountain. The results provide a foundation for investigating the history of syn-orogenic basin evolution, crustal mixing, and ancient topographic growth associated with regional tectonic activities. I have also been involved in multiple projects in Taiwan, the Northwest Pacific of the United States, and New Zealand, investigating sediment-related river incision processes, the origin of landslides, and the interactions and feedbacks among topographic evolution, climate change, and tectonic activities.
