I am a second-year PhD student in Earth and Planetary Sciences, supervised by Professor Penny Wieser. I investigate how magmas form, migrate, and erupt, with the goal of improving eruption forecasting and reducing volcanic hazards. I grew up exploring the volcanic terrains of Taiwan and the sills along the Hudson River, where minerals and fumaroles first sparked my curiosity about Earth’s inner workings. That early fascination has evolved into a scientific drive to understand magmatism from source to eruption.

I earned a B.A. in Earth Science from Columbia University and an M.Phil. in Earth Sciences from the University of Cambridge as a Euretta J. Kellett Fellow. After, I worked as a Data Science Fellow in the Geoinformatics Research Group at the Lamont-Doherty Earth Observatory of Columbia University. I now study high-threat volcanoes in the Cascade Arc. By analyzing crystals and the inclusions trapped within, I aim to constrain magma storage depths and timescales of magma mixing and ascent to better interpret signs of volcanic unrest. My approach blends geochemistry, data science, and machine learning to extract insights from complex geological records. Outside of research, I enjoy rowing, hiking, and cooking.
