James E Gardner is a Professor in the Department of Earth and Planetary Sciences at the Jackson School of Geosciences, University of Texas at Austin, holding the Third Mr. and Mrs. Charles E. Yager Professorship. His research focuses on volcanic eruptions, magmatic processes, and experimental petrology, with emphasis on bubble nucleation in magmas and caldera-forming eruptions. He leads a state-of-the-art experimental laboratory capable of simulating high-pressure magma conditions (up to 1400°C and 5000 bars).
Key research areas include studying active volcanic systems globally (USA, Mexico, Kamchatka), experimental determination of volatile solubility in magmas, and the role of pre-eruption degassing in eruption dynamics. Recent work addresses multi-component volatile solubility, bubble nucleation mechanisms, and magma ascent rates. His experimental setups include cold-seal and TZM pressure vessels for studying melt degassing under controlled conditions.
Publications span 20+ years, emphasizing bubble nucleation kinetics, pyroclastic density currents, and silicic magma evolution. His work integrates field observations with laboratory experiments and numerical models to understand volcanic hazards and eruption processes. The experimental lab under construction will advance studies on magma-volatile interactions and ore body formation linked to magmatism.
Notably, Dr. Gardner’s research bridges fundamental magma physics with applied volcanic hazard assessment, contributing to understanding explosive eruption triggers and conduit dynamics. His collaborative projects include NSF-funded studies on bubble nucleation models and lunar magma ocean processes.
