Courtney J. Sprain

Courtney J. Sprain serves as an Assistant Professor in the Department of Geological Sciences at the University of Florida, a position she began in fall 2020. She is establishing a dedicated 40 Ar/39 Ar geochronology laboratory within the department to support her research on Earth's historical evolution.

Her research integrates geophysics and geochemistry to investigate Earth's most dramatic historical events, employing paleomagnetism, numerical geodynamo simulations, and 40 Ar/39 Ar geochronology. Key focus areas include long and short-term trends in Earth's magnetic field and their implications for deep interior evolution, alongside developing precise geochronologic constraints for pivotal events like mass extinctions. This work bridges surface and deep-Earth processes to reconstruct planetary development timelines.

Dr. Sprain is actively recruiting graduate students for research in geochronology, paleomagnetism, and Earth History, with no current advisees named in the text. While no scientific awards or grants are specified, her laboratory development represents a significant institutional contribution. The geochronology lab under construction will enable high-precision dating crucial for understanding Earth's historical milestones and magnetic field behavior.
