Key Areas of Interest: Geophysics, Paleomagnatism

Teaching Areas: Geophysics

Research Interests: Most of my research centers around the field of paleomagnetism—the study of Earth’s magnetic field as recorded in rocks and sediments. My work can be subdivided into three main areas: understanding how Earth’s magnetic field has changed over time; using these “rock records” of changing magnetic fields and magnetic properties to interpret volcanic processes; and understanding how and how well magnetic minerals record the field.
