معرفی
Penny Wieser is an Assistant Professor at the University of California, Berkeley, specializing in igneous petrology and volcanology. Her research focuses on understanding volcanic systems through analysis of erupted materials (melts, crystals, gases, aerosols) and advanced analytical techniques like Raman spectroscopy, SEM, and LA-ICP-MS. She leads a research group investigating magma storage depths and volatile release mechanisms in volcanoes, particularly in Hawaii and other oceanic island systems. Her work emphasizes rapid-response methodologies and open-source Python tools for data analysis, such as VolFe and pyMELTScalc.
Key research areas include magma reservoir geometry, volatile degassing processes, and the interplay between petrological data and volcanic monitoring. Recent studies have addressed the plumbing systems of Mauna Loa, Kīlauea, and La Palma, with a focus on magma storage depth estimation using fluid inclusions and microstructural analysis. Wieser’s contributions bridge laboratory-based petrology with field observations, enhancing understanding of volcanic hazards and Earth’s dynamic processes.
Her office is located in Room 449 McCone Hall, and she maintains an active research group at her academic website. Notable tools developed include VESIcal and Thermobar for thermodynamic modeling of magmatic systems.
