Peter L. Olson

Peter L. Olson is a Professor in the Department of Earth & Planetary Sciences at Johns Hopkins University. He holds a Ph.D. in Geophysics from the University of California, Berkeley (1977). His research focuses on Earth's core-mantle dynamics, geomagnetic field generation, and planetary evolution. He is a Member of the National Academy of Sciences (2007) and a Fellow of the American Geophysical Union.

Olson combines theoretical models, numerical simulations, and laboratory experiments to study core dynamics, including the geodynamo, mantle plumes, and core-mantle interactions. Recent work explores the role of nebular atmospheres in terrestrial planet formation and the impact of core stratification on magnetic field behavior. His laboratory experiments on metal-silicate mixing and magma ocean dynamics have advanced understanding of planetary differentiation processes.

• Key Research Themes: Geodynamo mechanisms, core-mantle boundary processes, mantle plumes, planetary formation, and volatile delivery.
• Awards: National Academy of Sciences membership (2007), AGU Fellow, American Academy of Arts & Sciences membership.
• Labs/Teams: Collaborations with global researchers on projects involving numerical dynamos, mantle convection, and experimental geophysics.

His publications span over 50 years, with recent contributions addressing core evolution, geomagnetic dipole decay, and the influence of mantle convection on magnetic field reversals. He maintains an active role in mentoring graduate students and postdoctoral researchers.
