My research is currently focused on two interdisciplinary areas: (1) Coupling between the Earth's stratosphere and troposphere; and (2) mapping and interpretation of planetary crustal magnetic fields. The stratosphere / troposphere coupling work is oriented toward understanding the effects of stratospheric processes (mainly the QBO and solar forcing) on tropospheric circulation and climate. The planetary crustal magnetic field work is most recently aimed at mapping newly acquired orbital magnetometer data at Mercury and at resolving long-standing issues relating to the origin of lunar crustal magnetism.
