My primary research interests focus on tectonic processes in the offshore regions surrounding Taiwan. Key topics include the Western Taiwan Foreland Basin in the Taiwan Strait, rifting and seafloor spreading in the South China Sea, and gravitational collapse of the Taiwan orogenic belt.

Our main research tool is multichannel seismic (MCS) data acquired by the research vessel Ocean Researcher I operated by National Taiwan University. Multichannel seismic data allow us to image subsurface geological structures and identify the distribution of features such as faults, volcanic bodies, and sedimentary architectures, thereby providing insights into regional tectonic frameworks and their evolutionary processes.

In addition, we integrate complementary datasets that constrain seafloor morphology and shallow subsurface structures, including bathymetry and subbottom profiler data (SBP). To investigate deeper crustal structures, we further incorporate gravity and magnetic anomalies as well as ocean-bottom seismometer (OBS) observations. Through this multiscale observational approach, we aim to achieve a more comprehensive understanding of geological structures and the processes that shape them.
