ABOUT Me
I am currently a postdoctoral scholar at the Department of Earth and Space Sciences, University of Washington.
My research is centered on fluid-assisted mass transfer within subduction fault zones, specifically on how it impacts fault rheology and fluid dynamics along the depth of the plate interface due to its temperature- and depth-dependent nature. Ultimately, my goal is to gain insights into how these evolving factors shape the diverse fault slip behaviors that we observe.
I mainly utilize samples collected from several exhumed accretionary prisms, such as the Shimanto belt, Kodiak accretionary complex, and Olympic subduction complex to focus on three key aspects:
-
Determine the temperature range at which element transfer occurs using oxygen and clumped isotope thermometry
-
Estimate the strain magnitude and strain rate related to element redistribution via geochemical analyses
-
Evaluate the frictional behavior of ancient subduction fault rocks by performing friction experiments

I am also passionate about teaching and have been accumulating abundant teaching experience both in Taiwan and the US.
-
For geomajors, I focus on 1) developing lucid and interesting approaches to explain the theory and its application in the field and 2) introducing useful tools to cultivate students' hands-on skills.
-
For non-geomajors, I focus on introducing 1) how to see the world like a scientist, and 2) the environmental challenges that we are facing.
-
For the public, I believe outreach is crucial to 1) explain why is geology important to human society and 2) attract prospective students.
