My research focuses on unraveling the timescales of magmatic processes to reconstruct the life cycle of large volcanic systems. I combine geochemistry, geochronology, and diffusion chronometry to investigate the pressure–temperature conditions, tectonic triggers, and pre-eruptive histories of supereruptions, exemplified by my work on the Pangduo Caldera in the southern Tibetan Plateau. A central theme of my current research is how magma ascent rate influences eruption dynamics, which I explore at the Rabaul Caldera through NanoSIMS mapping of volatiles in apatite and subsequent diffusion modeling. By integrating in-situ analysis with numerical modeling, I aim to reconstruct the evolution of magma storage conditions and the role of volatiles, ultimately advancing our understanding of the processes that drive Earth’s most powerful volcanic events.
