Dear colleagues, We invite you to contribute abstracts to our interdisciplinary high-pressure science session at the 2025 AGU Fall Meeting: Synergizing Across Scales and Methods: Collaborative Advances in High-Pressure Earth and Planetary Science ( https://agu.confex.com/agu/agu25/prelim.cgi/Session/250515). This session focuses on interdisciplinary studies that integrate multiple high-pressure techniques such as large-volume press, diamond anvil cell, shock compression, and computational methods like DFT and MD, to investigate the behavior of planetary materials under extreme conditions. We welcome abstracts that combine methodological integration and experimental or computational techniques, and offer new insights into how integrating these methods enhances our understanding of the structure, dynamics, and evolution of Earth and planetary interiors. Session description: Understanding the behavior of Earth and planetary materials under extreme conditions often requires more than a single method. Recent progress in various experimental methods, such as large-volume press, diamond anvil cell, and dynamic compression, have provided new opportunities to study how materials behave under high pressure and temperature. Modern density functional theory and molecular dynamics, enhanced by machine learning, now enable realistic length and time scale simulations of complex phenomena with quantum accuracy. Integrating static, dynamic, and computational methods provides a clearer understanding of phase changes, elastic properties, and transport behaviors of materials in the interiors of Earth and super-Earth exoplanets. This session invites contributions that combine different high-pressure experimental and computational methods, discuss challenges in these approaches, and demonstrate how multi-method studies advance research in mineral and rock physics for planetary interiors. Studies that combine two or more experimental and computational methods are particularly encouraged. The abstract deadline is July 30, 2025. We look forward to seeing you in New Orleans.
